Why your skin feels dry even after moisturizing? The role of ceramides in melanin-rich skin 👉🏾

If your skin feels dry, tight, or dull, even after a full routine,the issue may not be hydration. It may be retention.

‍

QUICK READ

Hydration is easy. Retention is the real game.

Studies suggest that melanin-rich skin may have a different ceramide profile or lipid balance, which can affect how well it retains moisture and may contribute to increased water loss.

Ceramides play a key role in the skin barrier by helping limit moisture loss, while niacinamide has been shown in studies to increase ceramide synthesis, helping improve the skin’s ability to retain hydration over time.

GALSKIN BARRIER+ combines these two K-beauty–favored ingredients to support immediate barrier function and long-term moisture retention in melanin-rich skin.

Ceramides are not a trend. They are part of your skin’s infrastructure.

When people talk about “hydration,” they often think only about water. But skin does not stay hydrated just because it receives water. It stays hydrated when it can hold on to that water.

That is where ceramides matter.

Ceramides are among the key lipids in the stratum corneum, the outermost layer of the skin barrier. Together with cholesterol and free fatty acids, they help create the lipid matrix that limits water loss and supports barrier integrity.

Ceramides help form the lipid matrix that limits water loss and supports the skin barrier.

So what happens when skin has fewer ceramides?

Some comparative studies and reviews have reported that Asian skin tends to show the highest ceramide levels or ceramide/cholesterol ratio, while Black skin may show lower levels or a less favorable lipid balance.

NB: This should be presented as a documented tendency, not an absolute rule for every individual.

What that can mean in practice for black and brown skins:

• • A barrier with fewer ceramides may be less efficient at limiting water loss.
  • Skin may experience more dryness or “invisible dehydration” ( sometimes associated with oiliness, as the skin attempts to compensate for a lack of water by increasing sebum production ).
  • It may become more reactive to stress, irritation, weather changes, over-cleansing, or active ingredients

For melanin-rich skin, this matters even more:
barrier stress is more likely to be followed by visible uneven tone or post-inflammatory marks

Water hydrates. Lipids keep hydration in.

If the lipid structure is not optimal in melanin-rich skin, skin can feel dry even when the routine looks hydrating on paper.

Show me the research!

This isn’t marketing. It’s science

A 2003 review published in Dermatologic Clinics summarized evidence that stratum corneum ceramide content differed across ethnic groups, reporting higher levels in Asian skin and lower levels in Black skin. The same review also noted that findings on TEWL and other barrier parameters were mixed across studies.

A later review on racial and ethnic variations in skin barrier function reached similar conclusions, suggesting that ceramide content, stratum corneum structure, and overall barrier behavior may vary across populations, while emphasizing that the evidence remains heterogeneous and should be interpreted carefully.

Another review discussing moisturization across different skin types highlights studies showing higher ceramide levels in Asian skin and explores how these lipid differences may contribute to variations in barrier function and xerosis patterns.

More recently, a 2021 review in the Journal of Drugs in Dermatology reported that, in one comparative study of healthy volunteers, the highest ceramide-to-cholesterol ratio was observed in Asian skin and the lowest in African skin.

Why that matters for hydration

A skin barrier that is lower in key lipids or less optimally organized may be less effective at preventing transepidermal water loss, known as TEWL. TEWL is a standard way to assess how much water escapes through the skin barrier.

Higher TEWL generally reflects a weaker barrier.

This is important because many people assume melanin-rich skin is naturally “stronger” simply because it may appear more resilient. But barrier efficiency and visible skin appearance are not the same thing.

Reviews on skin of color note lower ceramide levels and greater TEWL in Black skin, which helps explain why dryness, ashiness, and barrier discomfort can coexist with skin that does not always look traditionally “dry” at first glance.

Why GALSKIN BARRIER+ focuses on two K-beauty–favored ingredients for melanin-rich barrier support

Hydration is not a single step. It’s a system.

At K+BROWN, we don’t just add water to the skin.
We focus on what melanin-rich skin often needs most: the ability to retain it.

Ceramides: seal the hydration NOW

Ceramides are essential lipids naturally found in the skin barrier.

• help support the skin barrier
• help reduce moisture loss
• help replenish essential skin lipids
• help improve the look of dry, stressed skin

They work at the surface level to help limit water loss and support immediate skin comfort.

Niacinamide: seal the hydration OVER TIME

While niacinamide is often highlighted in K-beauty for brightening, it plays another key role for melanin-rich skin: supporting ceramide synthesis and barrier function.

Studies have shown that it can:

• help support ceramide synthesis
• help reduce transepidermal water loss (TEWL)
• help improve overall barrier function

Over time, it helps support the skin’s own ability to retain hydration.

💧 A complete hydration system (beyond the barrier)

While barrier support is essential, hydration also depends on how much water the skin can hold.

That’s why GALSKIN BARRIER+ also includes:

• humectants (panthenol, betaine, trehalose) to help attract water
• polysaccharides (Mycomucin™) to help limit evaporation

Hydration levels, however, are a separate question.
