Understanding melanin is not only a question of aesthetics, but also of health and wellbeing, because plays a crucial role in protecting against UV damage. and in defining our specific skin care needs.
As we move into an era of inclusivity and recognition of diversity, the cosmetics industry has been forced to evolve, embracing a wider range of skin tones than ever before. In this post we look at how cosmetic products can enhance and protect melanin in all its forms.
What is melanin?
Melanin is the natural pigment that colours our skin, hair and eyes, and plays a crucial role not only in our appearance, but also in our protection against external damage.
It is produced by specialised cells known as melanocytes.located in the lowermost layer of the epidermis. The amount and type of melanin determines the variation in skin tones between different individuals and populations.
Types of melanin
There are mainly two types of melanin: eumelanin and pheomelanin.
Eumelanin, which is dark brown or black, is responsible for darker skin and hair tones.
On the other hand, pheomelanin, which is red or yellow, contributes to lighter skin tones, red hair and freckles. The ratio between these two types of melanin varies between individuals and is what ultimately determines the specific range of skin and hair colour.
Melanin functions
The primary function of melanin is to protecting the skin from damage caused by ultraviolet (UV) radiation from the sun.
By absorbing and scattering UV rays, melanin prevents them from penetrating deep into the skin, where they can damage the DNA of cells, causing premature ageing and increasing the risk of skin cancer. This is why people with a higher concentration of melanin in their skin have an increased risk of skin cancer. slightly lower risk of developing skin cancerThis does not eliminate the need for sun protection.
How to take melanin into account in skin care?
Melanin, more than just a pigment that determines the tone of our skin, is a natural strength against external aggressionsparticularly ultraviolet (UV) rays from the sun.
This biological shield, however, does not exempt anyone from essential skin care; rather, it underscores the need for a personalised approach to beauty routine and skin care for every shade.
Yes, sunscreen is for all skin types.
The first myth to debunk is thehe false belief that darker skins do not need sun protection.
Although melanin provides a natural barrier against sun damage, it is not foolproof. UVA and UVB rays can cause damage to any skin tone.including premature ageing, loss of elasticity and, most seriously, the risk of skin cancer.
For this reason, the choice of a suitable sunscreen with a SPF factor high is essential, preferably those formulated without white residue, which blend perfectly with all skin tones, celebrating natural beauty without compromising protection.
Specific care according to skin type
Melanin also influences the characteristics of the skin, such as its texture and the tendency to certain conditions, such as hyperpigmentation or post-inflammatory scars.
Products designed to address these concerns, ranging from topical treatments with ingredients such as vitamin C, kojic acid and niacinamideEven personalised routines that include gentle exfoliation and deep hydration can help keep skin radiant and healthy.
The most favourable ingredients for stimulating melanin
The choice of ingredients in cosmetic products can make a significant difference in the maintenance and health of melanin-rich skin.
Some components are particularly beneficial, helping to enhance natural luminosityto combat hyperpigmentation and protect against environmental damage. Below, we will highlight those ingredients that have proven to be particularly melanin-friendly:
Hyaluronic acid
Hyaluronic acid is a moisturiser par excellence. Capable of holding up to 1000 times its weight in waterThis ingredient is key to keeping skin hydrated, elastic and firm. For melanin-rich skins, which can sometimes show signs of dryness or roughness, incorporate hyaluronic acid products can help to achieve a smoother and juicier appearance.
Vitamin C
Recognised for its ability to brighten the skin and combat hyperpigmentation, the vitamin C is a powerful antioxidant which works to curb excessive melanin production in areas where uneven pigmentation has formed. It also fortifies the skin against exposure to pollutants and free radicals, contributing to a more even and radiant skin tone.
Niacinamide
The niacinamidevitamin B3, or vitamin B3, is a versatile ingredient that benefits all skin types, but is particularly effective on skins with high melanin concentration.
It helps reduce the appearance of dark spots, improves the skin barrier, reduces inflammation and increases skin elasticity. Its soothing and balancing action makes it an essential component in treating a variety of dermatological concerns.
Mild exfoliating acids
Acids such as glycolic, lactic and mandelic acids are excellent for promoting cell turnover and improving skin texture. However, the key with melanin is opt for mild formulations that do not irritate or cause post-inflammatory hyperpigmentation. Regular exfoliation with these acids can help reveal brighter, more even skin, minimising the appearance of scars and blemishes.
Retinol
The retinol is well known for its ability to accelerate cell renewal and stimulate collagen production. For melanin-rich skin, the use of retinol may help in the combating premature ageingIt is important to start with low concentrations and increase gradually. It is important to start with low concentrations and increase gradually, as retinol can be irritating if used incorrectly.
Sunscreen with physical filters
For melanin-rich skin, choose a sunscreen with physical filters. (such as zinc oxide and titanium dioxide) that does not leave a whitish residue is crucial. Not only do these ingredients effectively protect against UVA and UVB rays, they are also less likely to irritate the skin or cause hyperpigmentation.
