Dark Spots on Your Face: Where They Come From, How to Fade Them
A dark spot appearing on your cheek, cheekbone or the back of your hand isn't dirt you can scrub off. It's a deposit of melanin — the skin's natural pigment — that has concentrated in one place. Understanding why it concentrated there changes the answer entirely.
Where a dark spot comes from
The sun, in the large majority of cases
This is the most common origin. Under UV, the cells that make melanin overreact locally and deposit excess pigment. These spots — often called solar lentigines — appear on the most exposed areas: cheekbones, forehead, bridge of the nose, chest, backs of hands. They rarely arrive overnight: they're the bill for exposure accumulated over years.
Hormonal shifts
Pregnancy, hormonal contraception, certain treatments: hormones can trigger broader, blurrier pigmented patches, usually symmetrical, across the forehead, cheeks and upper lip. This type is particularly stubborn and returns at the slightest lapse in sun protection. If this sounds like you, a dermatologist's opinion beats an improvised routine.
Marks left by a blemish
After inflammation — a spot, a scratch, a reaction — skin can leave a brown mark where the lesion was. This is called a post-inflammatory mark. The good news: it's the type that fades best, provided you don't pick and you protect the area from sun while it resolves. See also our piece on blackheads, where the urge to squeeze causes exactly these marks.
What genuinely fades their appearance
1. Sunscreen — without it, nothing holds
Let's be blunt: this is the one non-negotiable item on the list. A brightening product used without daily sun protection is emptying a bath without turning off the tap. Pigment redeposits faster than it fades. TORVIA doesn't sell sunscreen — we'd rather tell you that than sell you something else instead. Get one, SPF 30 minimum, every day, including winter and overcast weather.
2. Gentle chemical exfoliation
Pigment sits partly in the surface layers of the epidermis. By speeding up the turnover of those layers, an alpha hydroxy acid like glycolic acid helps bring pigmented cells up and out faster. This is background work, not an eraser.
Glycolic Acid Serum
At night, twice a week to start. A night-cream version is available if your skin tightens easily.
3. Niacinamide
Niacinamide (vitamin B3) works differently: rather than exfoliating, it limits the transfer of pigment to surface cells. It's one of the best-documented actives in skincare, and one of the best tolerated — including by sensitive skin that can't handle acids. Details in our piece on it.
Niacinamide Brightening Serum
Morning, under moisturiser. Pairs fine with an acid at night.
4. Occasional physical exfoliation
A gentle scrub once a week can support the work, never replace it. Scrubbing harder speeds up nothing: the resulting irritation can even trigger fresh post-inflammatory marks.
Mint Exfoliating Facial Polish
Once a week, never the same night as the acid.
A realistic routine
- Morning: gentle cleanse, niacinamide serum, moisturiser, sunscreen.
- Night: makeup removal, cleanse, then glycolic acid serum two nights a week to start — never the same night as the scrub.
- Once a week: gentle scrub, on clean skin, without pressing.
Introduce one new active at a time, two weeks apart. It's the only way to know what suits you and what irritates you.
How long before you see a difference
Be honest about timeframes. A recent post-inflammatory mark can fade in weeks. A sun spot that's been there for years takes months of consistency, and won't disappear completely with topical products alone. No serum removes a spot in a week; any promise of that should send you running.
Give it eight to twelve weeks before judging — and take a photo at the start, in the same light. The change is too gradual for memory to measure accurately.
Frequently asked
Does lemon juice work on dark spots?
No, and it's actively risky. Lemon juice is photosensitising: applied to skin and then exposed to sun, it can cause a reaction that leaves darker pigmentation than what you were treating.
Can you use glycolic acid and niacinamide together?
Yes, by separating them: niacinamide in the morning, acid at night. Applying them back to back isn't dangerous, but it's the best way to irritate skin for no extra benefit.
What if the spot changes?
A spot that changes shape, colour or size, develops irregular edges, itches or bleeds has nothing to do with a skincare routine. Have it examined by a doctor without delay.
