What Are Bio-Active Lipids in Skincare?

Summary

  • Bio-active lipids include ceramides, fatty acids, and other lesser-known (but equally important) lipids like sphingolipids. 
  • These lipids play a vital role in maintaining healthy skin, boosting collagen and elastin, regulating inflammation, and improving hydration.
  • As we age, we naturally lose these bio-active lipids in our skin. But other factors, like sun exposure, environmental pollution, and lifestyle choices, can degrade our lipids too, leaving skin dehydrated, irritated, and prone to visible signs of accelerated aging. 
  • We can boost lipid loss with skincare products rich in bio-active lipids, seen in many formulas from serums to moisturizers. 

They are present in our skin, keep our complexions healthy and radiant, and are vital for everyday skin functions — learn all about bio-active lipids, why they are important, and how to incorporate them into your daily skincare routine.

What Are Bio-Active Lipids?

Remember the phrase bio-active lipids” because it’s likely to become much more commonplace and celebrated in the coming years. Bio-active is an umbrella term for these lipids, which include ceramides, fatty acids, and other, more under-the-radar options, like sphingolipids. These lipids play a vital role in maintaining healthy skin, boosting collagen and elastin, regulating inflammation, and improving hydration.

Why are these lipids so important? Our skin naturally produces these lipids, playing the crucial role of maintaining our skin’s health and function. Of course, we lose these bio-active lipids as we age, both naturally and via other factors (like sun exposure, environmental pollution, and lifestyle choices). This loss of lipids leads to the degradation of collagen and elastin, which, in turn, affects the structure and elasticity of the skin and accelerates visible signs of aging (along with a handful of other issues, like dehydration and a weakened barrier). This is also why skincare formulas that include bio-active lipids are so important; they help to replenish skin with a resource it knows well, recognizes and accepts easily, and already readily produces.

What Do Bio-Active Lipids Do for the Skin?

One cannot have healthy-looking skin if the bio-active lipids in the skin are depleted — that’s how vital these elements are for the skin. Here’s everything bio-active lipids do for the skin, in no particular order.

Nurture a Healthy Skin Barrier and Microbiome

The epidermis is upheld by these lipids, which form a complex matrix to keep the good in and the bad out. The barrier regulates hydration to keep skin moisturized while also preventing harmful bacteria and irritants from entering the skin. Much like a healthy skin barrier, these lipids also help regulate the skin’s microbiome. They control the types of bacteria that live on the skin, allowing good bacteria to thrive and bad bacteria to die off.

Control Inflammation

We often stress when our skin is in an inflammatory and immune response flare-up, but we can thank our lipids specifically for these issues. Bio-active lipids help regulate inflammation and the skin’s immune system, addressing everything from wounds to skin conditions (like acne and eczema). Indeed, lipids influence acne, which occurs with drastic changes in lipid composition. It’s also worth noting that sebum comes from lipids and, in part, regulates the skin’s microbiome, a vital part of healthy skin and a clear complexion.

Maintain Healthy Aging

Changes in lipid composition are linked with acne and other skin conditions. But these changes can also bring about an acceleration of visible signs of aging. These diverse and complex lipids love homeostasis and healthy skin, but when out of balance, they can lead to skin diseases, conditions, and accelerated signs of skin aging, like fine lines, wrinkles, hyperpigmentation, dehydration, and more.

Bio-Active Lipid Ingredients in Skincare

Now that your interest has been piqued in these buzzy bio-active lipids, let’s learn how they show up in our skincare ingredient lists. Here are a handful of the most common bio-active lipids that you’d find in skincare and what they do.

Ceramides

Ceramides are fats found in high concentrations in the uppermost layers of our skin. It’s estimated that up to 50 percent of our skin is composed of ceramides, and they perform the vital tasks of creating a protective barrier on the skin, preventing water loss, and restricting the entry of external stressors. Basically, ceramides help the skin function properly, working to protect and restore the skin barrier, which keeps skin looking and feeling hydrated and radiant.

Fatty Acids

Fatty acids, like essential fatty acids (EFAs), saturated fatty acids, and other forms of fatty acids, have an oddly phrased name, but they work wonders on the skin. Some of the most well-known forms of fatty acids include omegas (including omega-3 and -6), sapienic acid (a component of sebum), and lauric acid. They strengthen the barrier, improve skin hydration, give skin a more plump appearance, and reduce inflammation and redness.

Plant-Based Oils

Squalane, jojoba oil, and rosehip oil are just a few notable plant-based oils that are rich in bio-active lipids. They help to improve the skin barrier function, lock in moisture, calm irritation, plump skin, and balance the skin — qualities that almost all bio-active lipids accomplish.

The Best Bio-Active Lipid Skincare

Bio-active lipids can be found in many types of skincare products. They are often paired together to help reduce free radical buildup, which can contribute to inflammaging, boost collagen and elastin production, and reduce the appearance of fine lines and wrinkles. Here are just a few of our favorite forms of bio-active lipids, starting with our newest formulation.

A Lipid-Fortified Serum

While bio-active lipids are celebrated in many of Tatcha’s formulas, they play a key role in our new serum.

The Longevity Serum boosts skin resilience to visibly delay signs of aging, boosts surface cell turnover for smoother skin, visibly firms, and strengthens the skin. The formula works well with other serums, can be used morning and night in your existing skincare routine, and is ideal for anyone looking to boost their skin’s longevity.

To accomplish these impressive benefits, a super-concentrated extract of sashi-kusa, a herbaceous flowering plant, which is naturally rich in flavonoids, lipids, and phyto molecules, is steeped in nutrient-dense botanical butters and oils (murumuru butter, cottonseed oil, and linseed oil) that support natural collagen and elastin, visibly firming and reducing the appearance of fine lines.

Additionally, the Tatcha Institute uncovered a new benefit of glycerin through tireless research. An often uncelebrated ingredient prevalent in some of your favorite products, glycerin has been shown to work with the skin’s microbiome to activate a gradual release of key skin-renewing and -protecting nutrients – AHAs (like lactic acid) and fatty acids – that shield the skin from environmental aging factors.

A Redness-Soothing Barrier Cream

We can’t mention reducing redness and calming the skin without highlighting the bestselling and one-of-a-kind Indigo Overnight Repair treatment.

It’s earned the prestigious National Eczema Association seal of acceptance for its ability to soothe visibly irritated, eczema-prone skin, balance the microbiome, and cultivate good bacteria so skin performs at its optimal, symbiotic level. Featuring Japanese indigo, red sage root, ceramides (hello bio-active lipids!), hyaluronic acid, and mondo grass root for an immediate improvement in softness, smoothness, and radiance.

A Moisture-Locking Lip Mask

One area of the skin that especially needs a dose of moisture? The lips, which are where this iconic mask steps in to save the day.


The Kissu Jelly Lip Mask is more than just a balm, and can be used overnight to improve moisturization, plumpness, and smoothness, or it can be used any time of the day, too. With continuous use, the mask improves the lips' ability to retain moisture. It includes a few bio-active lipids, including squalane and camellia oil, too.

Frequently Asked Questions

Are bio-active lipids suitable for oily or acne-prone skin?
A common question is whether bio-active lipid formulas can clog pores and lead to breakouts. It’s a worthy question, but unfortunately, one that is not straightforward and easy to answer. In general, these lipids will do the opposite of breaking you out. Instead, supporting the lipid reserves of the skin and balancing them leads to equilibrium and a clearer-looking complexion. However, if some of the botanical stabilizers often paired with these lipids are not non-comedogenic, it could lead to breakouts. The Longevity Serum is non-comedogenic and is designed to work for all skin types, even oily and acne-prone.
Can bio-active lipids be layered with strong actives like retinol, vitamin C, or exfoliating acids?
Most bio-active lipid products play nicely with others, although ask your dermatologist if you have specific questions. As far as The Longevity Serum, it was designed to be used with all other skincare products, including actives like retinoids, vitamin C, and exfoliants. Because it works on strengthening the skin with nourishing ingredients, it can pair quite nicely with these formulas.
How do bio-active lipids compare to occlusive ingredients like petrolatum for repairing the skin barrier?
Great question! These are two different categories of skincare, but they enjoy working together to accomplish the same task (with the task being giving you the healthiest-looking skin possible). Bio-active lipids are present in the skin and are needed to support its overall wellness and appearance. Occlusives usually do not repair or support, but create a barrier on top of the skin, helping to shield external factors from entering and internal factors like moisture from leaving the skin. These two are best friends because bio-active lipids will get to work repairing and supporting the skin, and the occlusive on top of it will ensure that it is undisturbed while doing its job.
How can I tell if my skin is low on bio-active lipids—are there visible signs to watch for?
Damage can occur quite slowly, over time, until one day you realize there are visible signs of accelerated skin aging. Which is perfectly fine—we all age, and it is a privilege. But if you’d like to be more proactive, using a formula like The Longevity Serum will address low bio-active lipid levels before you notice the drastic changes in your complexion. But visible signs that you might be low on bio-active lipids are excessive dehydration, irritation, an inability to balance the skin, accelerated signs of skin aging, and common skin issues like eczema and acne. They could all be communicating an issue to you without you picking up on it.

The Best Foaming Facial Cleanser

Foaming cleansers can be effective for all, but the secret to using them correctly is discovering a formula that is ideal for your skin type. A creamy foaming cleanser, which imparts a soft hydration onto the skin as cleansing, is more ideal for dry skin, while a refreshing foaming cleanser that includes oil-balancing ingredients is more ideal for combination and oily skin tones. Some formulas work by allowing the dense bubbles to grasp onto debris, sebum, and makeup, washing away in a single step. While other formulas might need an oil cleanser first to break down these trickier long-lasting ingredients.

The Best Blemish Begone Skincare Products

Blemishes can be caused by a variety of things, and are a fact of life. But choosing the right skincare products can help you keep breakouts at arm’s length. Blemishes happen to all of us. But to some of us, they happen more often than not. We call ourselves blemish-prone. And in addition to our usual skincare routines for morning and night, we make active choices about the products we use to make sure blemishes stay away. The word blemish, from the French blessmiss—to make angry—might be the most polite way to refer to many types of skin blemishes like acne, pimples, zits, and all of the other names we ascribe to those skin reactions that cause small unusual bumps. A bit ironique, considering that the word we now associate with acne connotes an imperfection or something else wrong. And while acne can be caused by imbalances in the skin, it’s common enough for all of us not to make it such a big deal. These are not mountains. They’re even much smaller than molehills. Still, those who deal with blemish- or acne-prone skin know that not all skincare products are created for the same skin type. All of us need to choose the right cleanser and moisturizer for our skin, but how we do so is up to us—and, usually, to the specifics of our skin’s behavior. A dermatologist should be your first stop on your skincare journey, but the following guide can help shed a little light on the acne-prone skin type, and some of the common skincare choices (and the optimal acne skincare routine!) made by those who have it. What is blemish-prone skin? Blemish-prone skin is another term for oily skin, which is one of the major skin types. Oily skin is usually categorized by skin that produces more sebum than so-called “normal” skin, but there are a few ways to glean more information about how your skin behaves at baseline. “Oil” is a poetic name for sebum, the waxy substance made of lipids like cholesterol, squalane, and glycerides that is secreted from sebaceous glands that sit within pores and hair follicles. Sebaceous glands are an important mechanism that our skin uses to moisturize and protect itself. Many of our sebaceous glands can be found on our faces and scalps, though there are a few places we don’t have sebaceous glands—like on our lips, or the bottoms of our feet. Sebum is a protective substance that helps to seal moisture by shoring up our skin barrier. In other words, it’s a good thing to have. But those with oily skin can have too much of it, and too much can lead to a higher incidence of breakouts. While oily skin can be a genetic trait, it can also be influenced by the environment around us—the climate, for instance—and our own behaviors—like how we take care of our skin. How do blemishes occur? You’re unlikely to find the term “blemish” in dermatology coursework. Generally, when we’re talking about a blemish, we’re talking about a form of acne, which is described most concisely as a blocked hair follicle. The pores that dot our skin are small channels that house sebaceous glands and hair follicles; they help traffic sebum up and out of skin. When sebum and dead skin clogs a pore, it may become what is called “common acne”, though there are a few types. Blackheads and whiteheads are caused by sebum buildup, and are distinguished by whether or not they’re open (and black) or closed (and white). When an infectious bacteria is introduced, it can cause a more robust infection, resulting in other forms of acne like papules and pustules that are painful to the touch. If you need help identifying what kind of blemish has popped up on you, head to your nearest dermatologist’s office to find out. What are the most important blemish skincare steps? Perhaps the most important thing to do in the face of acne is: Not panic! Breakouts happen to all of us, and usually fix themselves on their own. But if you identify with the oily skin type, and find yourself devoting more time to quelling breakouts than you’d like, you might want to consider some of the skincare products for oily skin, which are popular among those with acne-prone skin. A few common switches include: Cleansing with a gel. Dermatologists at the University of Florida Health once proclaimed that “the most important thing you can do for oily skin is to keep your skin clean.” Those with oily skin may want a cleansing formula with more reach than surface-level face washes—something that can cleanse pores deeply, ensuring they remain clear of acne-causing buildup. Gel cleansers are usually the ones for the job. Water-based gel cleansers are slippery, clear, and tend to foam up. Tatcha’s brand new Matcha Cleanse is a soapless gel that deeply decongests pores— thanks to a unique gel-to-foam texture—to reduce oil, and visibly calm skin without stripping. The Matcha Foam Cleanser takes on oiliness with a gentle touch: balancing the microbiome, soothing, and calming. Exfoliating with acids. There’s a reason that the inventors of alpha hydroxy acids have been honored all over the world. Their contribution to skincare includes one of the most popular exfoliating acids of all time—and it’s a boon for those with oily skin. AHAs, as they’re known, help to “peel” the skin by breaking down the bonds between old and new skin cells. Exfoliation is essential for all skin types, but the ease of AHAs and their efficacy in removing dead skin makes them great for oily skin. They’re commonly recommended to those with oily and acne-prone skin, especially in the form of a daily treatment. A product like the Texture Tonic, which takes the form of a lightweight daily toner, allows you to fit gentle exfoliation into your regular skincare routine—right between cleansing and moisturizing. Its AHAs come from a cornucopia of fruit sources proven to resurface uneven and dull skin—leaving it smooth and radiant. Moisturizing with water Sure, the idea of moisturizing with nothing but water may sound counterintuitive, or downright impossible. And yet it's the animating idea behind the Water Cream, Tatcha’s best-selling moisturizer for oily skin. This lightweight, oil-free cream has a bursting effect when applied, flooding the skin with vital and necessary hydration. It’s also beloved for its powerful superplant ingredients that address traits commonly found in oily skin, like antioxidant-rich wild rose (which has the benefit of smoothing the appearance of large pores) and anti-inflammatory heartleaf extract (a natural azelaic acid alternative). Masking with clay When it comes to natural ingredients that help oily skin, you can’t beat clay. Clay helps absorb excess oil, and is said to also draw impurities out of the skin. Anyone who has used a clay mask can attest to its drying powers, which is why it’s not usually a daily ingredient. Instead, it's suited for more irregular use, like in a face mask. The Clarifying Clay Mask, formulated as a treatment for oily skin, uses marine mineral-rich kucha clay sourced from the islands of Okinawa. For centuries prior, Okinawan women have cherished kucha clay for its superb oil-absorbing properties, using it as a hair powder or face mask. When mixed with volcanic ash and exfoliating Japanese konjac, it makes for smoother, clearer skin in no more than three minutes. 180 seconds per week may not alone calm oily or blemish-prone skin, but good holistic skincare habits will.
