Melanin-rich skin , found in people with dark or mixed-race skin, possesses unique characteristics. Contrary to popular belief, melanin doesn't just offer natural protection against the sun; it also influences skin sensitivity and how the skin reacts to external aggressors. This is why, regardless of skin type— dry, combination, oily, or normal—melanin-rich skin can be naturally sensitive .
1. A naturally more reactive skin barrier
The skin barrier of melanin-rich skin has a slightly different structure. Although thick and resilient, it may be less effective at retaining moisture . This susceptibility explains why dark skin is often prone to:
- dehydration
- tensions
- reactions to cosmetic products
- mild but persistent inflammation
A weakened skin barrier also means increased reactivity , even in oily skin.
2. A rapid reaction to melanin production
Melanin is a powerful protector, but it is also highly reactive to irritation . Even the slightest inflammation can cause the skin to produce more pigment. This explains why skin rich in melanin is more prone to:
- hyperpigmentation
- brown spots
- post-inflammatory spots
- persistent marks after pimples or irritations
The skin therefore reacts more to friction, aggressive exfoliants or certain poorly dosed active ingredients.
3. Increased sensitivity to irritants
Black and mixed-race skin can be particularly sensitive to certain ingredients frequently found in facial care products :
- drying alcohol
- perfumes
- exfoliating acids that are too concentrated
- poorly suited retinoids
- irritating skin-lightening agents
This sensitivity is not due to fragility, but to a more pronounced inflammatory response , which increases the risk of hyperpigmentation.
4. Sebaceous glands that react differently
Skin rich in melanin often produces more sebum, giving the illusion of less sensitive skin. However, sebum does not prevent:
- irritations
- micro-inflammations
- internal dehydration
It is therefore common to have oily and sensitive skin at the same time.
5. Impact of external aggressions
Pollution, sun, cold, or mechanical friction (such as from cotton clothing, scarves, and pillowcases) can cause:
- invisible irritations
- micro-inflammations
- pigment spots
- sensations of discomfort
Skin rich in melanin therefore requires a suitable routine that respects its unique physiology.
Conclusion
Melanin-rich skin is beautiful, complex, and resilient, but it can also be naturally sensitive . Its specific function makes it more reactive to inflammation and more prone to developing hyperpigmentation. Understanding these mechanisms allows you to choose the best skincare for Black and mixed-race skin : gentle, hydrating, non-irritating formulas designed to maintain the skin barrier and prevent dark spots.
A suitable routine = radiant and healthy skin.
