Melasma Causes And Treatment

Melasma is those stubborn brown or gray patches that show up on your face, usually on your cheeks, nose, or forehead. It's super common and totally treatable, but understanding what triggers it is the first step to getting your skin back.

How hard is this to fix?

Depends on the cause, but with the right routine it almost always improves.

High — takes months

Why it happens

Sun exposure is the biggest culprit—UV rays trigger your skin to make extra pigment. Hormones from birth control or pregnancy can also spark it. Genetics play a role too; it's more common in people with darker skin tones.

Sun exposureThe sun is the main cause of dark spots. Even a few unprotected minutes daily add up over time.
HormonesPregnancy and birth control pills can cause melasma-type pigmentation.
Post-inflammatory marksSpots left by pimples and wounds, especially on darker skin tones.
Skin agingOver time skin distributes pigment less evenly.

What makes it worse without you realising

Skipping sunscreen daily won't help it fade. Using too many strong products at once can actually irritate your skin and make patches darker. Also, expecting overnight results sets you up for disappointment—this takes patience.

Always check the ingredients

Many products sold as gentle contain fragrance. Look for parfum or fragrance in the ingredient list.

What to do about it

Daily SPF 30+ is non-negotiable. Look for brightening ingredients and consider talking to a dermatologist about professional treatments. Consistency matters more than trying every trendy product at once.

Frequently asked questions

Do sun spots disappear?
With the right products they fade significantly, but it takes 2-3 months of consistent use. SPF is essential to prevent them coming back.
Vitamin C or niacinamide for dark spots?
Both work but differently. Vitamin C is more direct, niacinamide is gentler. For sensitive skin, start with niacinamide.
Does sun bring back dark spots?
Always. Without SPF 50, any anti-pigmentation treatment is pointless.
Do pregnancy marks fade on their own?
Sometimes they fade after birth, but often stay. Melasma responds well to niacinamide and sun protection.
