Contrary to popular belief, pigmented skin is not naturally protected against the harmful effects of the sun. Yes, it tans more slowly, but it can still burn, age prematurely… and especially hyperpigment. UV exposure is one of the main triggers and aggravators of pigmentation spots. That’s why sun protection is a crucial part of any dermocosmetic routine.
Why does dark skin pigment more when irritated?
Melanin acts as a double-edged sword: it protects against UV rays… but it also reacts intensely to any kind of stress. Sun, pimples, wounds, even irritation can lead to excessive localized melanin production—this is known as post-inflammatory hyperpigmentation (PIH).
This phenomenon is amplified without sun protection because:
- UV rays fuel inflammation,
- they oxidize skin cells,
- they lock in pigmentation over time.
Recent studies show that darker skin develops more low-grade inflammation when exposed to the sun without UV filters, which promotes chronic pigmentation (source: J Am Acad Dermatol, 2022).
What to expect from a suitable sunscreen
Not all sunscreens are created equal—especially for pigmented skin. The right product should:
- offer high SPF (minimum 50) to block both UVB and UVA rays,
- be non-whitening, for an invisible finish on dark skin,
- hydrate without clogging pores, with light, mattifying textures,
- be photostable, meaning it remains effective after several hours of sun exposure.
Laboratoire IN’OYA has developed an SPF 50 sun fluid specifically for Black, brown, and mixed skin: invisible, non-comedogenic, and non-whitening, it protects without disrupting your complexion.
Sun protection: apply even in the city
Many people think sunscreen is only for vacations or beach days. That’s a mistake. Even in the city or under clouds, UVA rays pass through windows and penetrate the skin.
On pigmented skin, this silent urban exposure is enough to reactivate old pigmentation or set in existing dark spots.

It is recommended to apply sun fluid every morning, even for short outings, and to reapply in case of sweating or prolonged outdoor activity.
Sun protection & dark spot treatment: an inseparable duo
No dark spot treatment, no matter how effective, works fully without sun protection. Worse: some depigmenting actives (kojic acid, vitamin C, retinoids…) can increase photosensitivity.
Without SPF, new spots may appear, or existing ones may worsen.
To optimize an anti-dark spot routine, you must:
- apply SPF 50 every morning,
- avoid direct sun between 11 a.m. and 4 p.m.,
- wear a hat or sunglasses when needed.

What about children, men, oily skin?
Sun protection is for everyone. On young skin, it prevents early spots. For men, it helps with pigmented ingrown hairs. On oily skin, it reduces post-acne spots.
The key is to adapt the texture:
- Mattifying fluid for oily skin,
- Protective moisturizing cream for dry skin,
- Water-resistant formulas for children.
The texture of sunscreen is essential to ensure regular use: when pleasant, application becomes a daily habit.
In summary
- Sun protection is essential to prevent hyperpigmentation in Black, brown, and mixed skin.
- It’s not just for vacations or summer: it’s a daily need.
- A good sunscreen should protect without leaving white residue or causing irritation.
Subtle note: IN’OYA’s SPF 50 sun fluid is specifically formulated for pigmented skin. Invisible and highly tolerated, it fits all routines—even those targeting spots, pimples, or imperfections.
