A very common question asked is “if I have more melanin, do I still need sunscreen?”. It is actually a very fair thing to wonder. Much of the material written about sun protection treats skin as if it’s all the same. But what melanin is doing is something remarkable underneath the surface of the skin and understanding it changes how you think about SPF entirely.
What Melanin Actually is (and What it’s doing All Day)
Melanin is a pigment which is produced by cells called melanocytes which are situated in the lower layer of the epidermis. Its job is much more than just giving our skin, hair and eye their colour. Melanin is also a natural defence mechanism. It can absorb and scatter ultraviolet radiation before it can damage the DNA inside the skin cells. You can think of melanin as a filter that has been evolving for thousands of years much before anyone had heard of SPF numbers.
When UV light hits the skin, melanocytes respond by producing more pigments and distributing it to the surrounding keratinocytes, which is the tanning process you see happen over a few days of sun exposure.
Eumelanin vs Pheomelanin
Not all types of melanin are the same. The two main types of melanin are eumelanin & pheomelanin. Eumelanin is brown-black and offers stronger UV protection. Pheomelanin which is reddish and yellow offers much less UV protection. Individuals with darker skin tones generally tend to produce more eumelanin, which is part of why deeply pigmented skin has a naturally higher built-in SPF. This higher SPF is estimated in reach to be around 13 or higher. In contrast those with fair skin who have more pheomelanin have much less protection and burn more easily.
How UV Radiation Reaches Your Skin
The sun sends down to earth a spectrum of radiations, but the two types that matter most for the skin are UVA and UVB rays. UVA rays have a longer wavelength and can penetrate deep into the dermis. When they have penetrated the dermis, they break down collagen and elastin over time which is largely responsible for the appearance of fine lines and sagging. UVB rays are shorter and are more intense and they are the ones primarily responsible for sunburn and can cause direct DNA damage to surface skin cells.
Melanin is able to absorb both, but its efficiency is not infinite. Once UV exposure exceeds what your existing melanin can neutralize is when you will see redness, inflammation and burn.
The Sunburn Response: what’s Happening Beneath the Surface
A sunburn is the visible signs of cellular injury. When UVB radiation overwhelms the
skin’s melanin defence it damages the DNA in Keratinocytes. The body responds to this by triggering inflammation and dilating blood vessels near the surface. This is why skin turns red and feels hot. In certain sever cases those cells which are too damaged to repair self-destruct in a process called apoptosis. That is the peeling you see days later. It is the skin clearing out cells it could not save.
This is also why sunburn is not just a short-term discomfort. Repeated UV damage accumulates over a lifetime, and it is one of the clearest, most well documented risk factors for premature aging and skin cancer.

Why Melanin Alone Isn’t Enough
Skin Tone, Sun Sensitivity and Fitzpatrick Scale
The Fitzpatrick scale is used by many dermatologists to classify how skin responds to UV exposure. This scale ranges from typed 1 which burns easily and never tans to type 5 which rarely burns and can tan deeply. It is useful framework. However, there is an important misconception to address. Higher melanin levels do not mean sun protection is not necessary. It genuinely is not true. Melanin can reduce the risk, but it does not eliminate it. UVA damages does not discriminate nearly as much by skin tone. Hyperpigmentation, dark spots and uneven texture can affect any complexion when sun exposure goes unmanaged.
How to Protect Your Skin Using CHOLLEY Sun Protection
To understand the protective role of melanin is important but do not use it as a reason to rely on pigmentation alone. At CHOLLEY we believe daily sun protection should complement the skin’s natural defences.
For higher levels of everyday UV exposure, we recommend CHOLLEY Alpine Solar Défense SPF 50. It provides both UVA and UVB protection while helping to provide protection to the skin from the effects of environmental exposure. We find it particularly useful on sunny days, during prolonged outdoor exposure or when spending a lot of time near windows.
For a lighter daily skincare routine, CHOLLEY Edelweiss Cream SPF 20 combines moisturizing skincare with SPF protection. It is designed as a daytime cream and can be a convenient option when you want hydration and daily UV protection in one step.
Why Daily Sun Protection Still Matters
Even when the skin contains higher levels of eumelanin, it is still exposed to UV radiation. Melanin can provide natural protection to the skin, but it does not block all UVA and UVB rays.
That is why we prefer to look at sunscreen as an additional layer of protection, rather than something that replaces the skin’s natural defences. Using an appropriate SPF, seeking shade and limiting prolonged exposure can all help to reduce cumulative UV damage.
At CHOLLEY our approach is simple: work with the skin’s natural protection but do not reply on it alone.
Frequently Asked Questions
Does melanin protect your skin from the sun?
Yes. Melanin absorbs some UV radiation and provides natural protection. However, it does not block all UVA and UVB rays, so sunscreen remains important.
Do people with darker skin need sunscreen?
Yes. Higher levels of eumelanin provide greater natural UV protection, but darker skin can still experience sunburn, hyperpigmentation, photoageing and UV damage.
Does eumelanin protect better than pheomelanin?
Yes. Eumelanin generally provides stronger UV protection than pheomelanin, which absorbs less UV radiation and may contribute to oxidative stress.
Can people with dark skin get sunburned?
Yes. Darker skin is generally more resistant to sunburn, but prolonged UV exposure can still cause burning and long-term skin damage.
Does tanning increase melanin?
UV exposure can stimulate melanin production, causing the skin to tan. However, tanning is still a response to UV exposure and should not be considered a safe form of sun protection.
Does melanin protect against UVA and UVB?
Melanin provides some protection against both. However, it cannot completely prevent UVA-related photoageing or UVB-related sunburn and DNA damage.
What SPF should people with more melanin use?
Everyone should use appropriate broad-spectrum sunscreen. The ideal SPF depends on factors such as skin type, UV levels and exposure time. CHOLLEY Alpine Solar Defense SPF 50 provides higher SPF protection.
Can melanin prevent premature skin ageing?
Melanin offers some protection against UV damage, but it cannot completely prevent photoageing. UVA exposure can contribute to wrinkles, pigmentation and collagen damage.
Does sunscreen work if you already have more melanin?
Yes. Sunscreen adds another layer of protection and should not be considered unnecessary because of naturally higher melanin levels.
What is the difference between CHOLLEY Alpine Solar Defense SPF 50 and Edelweiss Cream SPF 20?
Alpine Solar Defense SPF 50 provides higher SPF protection for greater UV exposure. Edelweiss Cream SPF 20 combines daily moisturising care with SPF protection.
