Pigment guide
Hyperpigmentation is excess melanin left behind after inflammation, hormones, or UV exposure. Fading it takes two things in parallel: an ingredient that slows new pigment production, and sunscreen that stops the spot being re-triggered every day. Everything else is optional.

A skincare routine for hyperpigmentation needs two things every day: broad-spectrum SPF 30 or higher in the morning, and one pigment-fading active used consistently, such as azelaic acid, tranexamic acid or a retinoid. Vitamin C is a supporting option. Post-acne marks often take months to fade, and the AAD says melasma usually takes 3 to 12 months to improve.
Start here
The three common types look alike but respond differently. Knowing which one you have decides how gentle to be and when to get help.
| Type | What it looks like | What usually helps | See a dermatologist |
|---|---|---|---|
| Post-acne marks (post-inflammatory hyperpigmentation) [7] [8] [11] | Flat brown, gray or dark marks where a spot, rash or irritation was. They tend to last longer on deeper skin tones. | Daily sunscreen, a gentle routine with no picking, and one active such as azelaic acid or a retinoid. | When marks keep appearing, keep spreading, or have not changed after several months. |
| Melasma [1] [2] [12] | Brown or gray-brown patches, often on both cheeks, the forehead or the upper lip. Sun and hormones are common triggers. | Strict sun protection with a tinted, iron-oxide sunscreen. Prescription options such as hydroquinone, the triple cream or tranexamic acid come from a dermatologist. | Get a diagnosis. Peels, lasers and microneedling can make melasma worse, so leave them to experts. |
| Sun spots [1] [2] | Small flat spots on the face, hands and other places the sun hits most. | Daily broad-spectrum sunscreen first. Our sources hold little review-level evidence for home actives on sun spots. | Any spot that changes shape, border or color, or looks different from the others. |
Evidence check
A means strong trials or guideline support, B means some trials, C means limited or mostly lab evidence. Each grade names the condition it applies to, because most of the strong evidence is for melasma. Graded Oct 2026, reviewed by Maria Alejandra. Read how we research.
| Ingredient | What it does | Grade, by condition | Safety and access | Sources |
|---|---|---|---|---|
| Broad-spectrum SPF 30+ and tinted iron-oxide SPF | Blocks the UV that re-darkens pigment. Tinted iron-oxide formulas also block visible light. | Melasma: A. The base step for post-acne marks and sun spots too. | Zinc oxide, titanium dioxide and iron oxide are the filters the AAD lists. | [1] [2] |
| Hydroquinone | Lowers pigment production. Part of the triple cream. | Melasma: A. | Prescription only in the US. Use it only under a dermatologist's care. A systematic review lists ochronosis, a bluish-gray darkening, as a theoretical risk. | [1] [2] [3] [4] |
| Azelaic acid | Slows excess pigment production and is well tolerated. | Melasma: B, close to B+. Comparable to hydroquinone in a meta-analysis of 3 studies. | The AAD lists it as a gentler prescription option. 20% is a strength quoted in the sources. | [1] [3] [6] |
| Tranexamic acid, topical | Applied to the skin to reduce melasma patches. | Melasma: B. Better than placebo and similar to hydroquinone, not as strong as the triple cream. | Lowest irritation rate (0.8%) in the meta-analysis. | [3] [4] [5] |
| Tranexamic acid, oral | A pill a dermatologist may add when melasma does not respond to other treatment. | Melasma that has not responded: A. | Prescription only. A clinician reviews your health and any blood-clot history first. We do not give dosing. | [1] [2] [4] |
| Retinoids (tretinoin, adapalene) | Speed up cell turnover so pigmented cells shed sooner. | Post-acne marks: tretinoin B, adapalene C to B. Melasma: A only as part of the triple cream. | In one 40-week randomized trial of 54 people, tretinoin lightened marks in 40% versus 18% on placebo, and half had retinoid dermatitis. Check pregnancy use with your clinician. | [9] [7] [8] [1] |
| Vitamin C (ascorbic acid) | Antioxidant. A supporting option, not a lead treatment. | Melasma: C. | Poor skin penetration. In one split-face trial, 15% of people with melasma improved. | [6] [1] [2] |
| Niacinamide | Studied for reducing pigment transfer to surface skin cells. | Melasma: C, close to C+. Small studies, mostly in combinations. | Generally well tolerated. No pooled evidence yet. | [6] |
| AHAs (glycolic acid) | Exfoliate so pigmented cells shed faster. | Post-acne marks: C for home products, B only as in-office peels, from small studies (one with 19 people). | Peels can worsen melasma or post-acne marks, so they belong with an expert. | [10] [2] |
| Kojic acid | Lowers pigment production. | Melasma: B- to C. The weakest effect among the agents that worked, across 6 studies. | Irritation in 5.3% of people in the meta-analysis. | [3] [1] |
| Arbutin and licorice | Plant-derived pigment inhibitors. | Melasma: C. No review-level data found for licorice on its own. | Arbutin lowered melasma scores in trials but can cause redness and itch. | [6] [4] |

Ramp-up
Weeks 1 to 2
Sunscreen every morning, a gentle cleanser and moisturizer. Patch test one pigment-fading active and start it two or three nights a week.
Weeks 3 to 6
If skin stays calm, use a simple rotation: azelaic acid or topical tranexamic acid one night, a retinoid the next, then a plain recovery night. Back off at any stinging or peeling, since irritation can create new marks.
Weeks 7 to 12
Keep the same products. Take a photo every two weeks in the same light so you compare like with like, and do not switch serums mid-plan.
After week 12
Post-acne marks often take months. The AAD says melasma treatment usually takes 3 to 12 months to show results, and longer if it has been there a long time. If nothing has changed, or your skin is irritated, see a dermatologist.

Variations
Same two jobs in lighter textures: a gel cleanser, a fluid sunscreen and a gel moisturizer. Azelaic acid and adapalene both fit breakout-prone skin. Add one at a time so new breakouts do not leave fresh marks.
Oily skin routineStart with sunscreen and azelaic acid or topical tranexamic acid, which had the lowest irritation rate in the meta-analysis. Leave retinoids and acids until skin has been calm for several weeks.
Sensitive skin routineMarks last longer, and harsh scrubs or strong peels can leave new ones. Choose gentle actives, introduce them slowly, and pick a sunscreen with no gray cast so you wear it daily.
Routine for deeper skin tonesSome actives on this page are not suitable in pregnancy and others need advice. Check every active with your clinician before you start.

Dark spots respond slowly and only to consistency. Three jobs matter:
Vitamin C, niacinamide, azelaic acid, tranexamic acid, and alpha arbutin each slow the enzyme pathway that creates pigment.
A retinoid or gentle acid moves already-pigmented cells to the surface so the spot fades faster.
Daily broad-spectrum SPF 30+ is non-negotiable. Without it, UV re-darkens spots faster than actives can fade them.
Morning ritual
Mornings are about antioxidants and protection — the half of the routine that prevents new pigment.
Gentle non-foaming cleanser. Harsh surfactants cause the inflammation that drives more pigment.
Vitamin C 10 to 15% (L-ascorbic acid or a stable derivative) to brighten and defend against UV damage.
Lightweight moisturizer with niacinamide 5% to support the barrier and reduce pigment transfer.
Broad-spectrum SPF 30 to 50 every morning, reapplied at midday. Tinted mineral SPF also blocks visible light, which worsens melasma.
Evening ritual
Evenings are for turnover. Introduce one active at a time. Dark marks left after acne or irritation usually fade within 6 to 12 months once the cause is stopped, and deeper marks can take longer; melasma usually takes 3 to 12 months of consistent treatment to improve (American Academy of Dermatology). Creams for sun spots need daily use for weeks or months (AAD).
Oil or balm cleanser to remove SPF fully, then your gentle cleanser.
Azelaic acid 10% or tranexamic acid on alternate nights — both are safe for melasma and darker skin tones.
Retinol or adapalene can support turnover; follow the product or prescriber directions, start cautiously, and use moisturizer if it improves tolerance.
Ceramide moisturizer. A calm barrier means less inflammation, and less inflammation means less new pigment.
Antioxidant studied for tone evenness and for supporting sunscreen against UV-driven pigment.
Why I suggest itI pair it with SPF rather than treating it as a standalone brightener, because the daytime benefit reported in the literature is protective as much as corrective.Cosmetic Ingredient Review — ingredient safety assessments
Studied for interrupting pigment transfer to surface skin cells, and for visible redness.
Commonly used for post-acne marks and melasma, and generally considered suitable in pregnancy.
Why I suggest itIt is the option I reach for first when someone is pregnant or reacts to retinoids, since obstetric guidance treats topical azelaic acid as a reasonable choice.ACOG — skin conditions during pregnancy
Studied for stubborn melasma and hormonal pigmentation.
Increase turnover so pigmented cells shed sooner.
The step treatment starts with — fading products tend to work better once skin is protected from the sun.

Reality check
| What it can do | What it cannot do |
|---|---|
| It can sit in a routine aimed at uneven tone and a less shiny look. | It cannot bleach a mark, and a higher percentage is not automatically a better one for your skin. |
Pigment routines run several actives at once, so the cleanser's only job is to be gentle and get out of the way.

Keep pores open with one consistent active, calm inflammation, and never strip the barrier, because irritated skin breaks out more.
Roughly 80% of visible facial aging is caused by UV exposure, not time. That makes the routine simple in principle: protect during the day, use a retinoid at night (the most studied topical for the look of fine lines), and keep the barrier hydrated so lines look softer immediately.
Dullness is usually light, not pigment. A build-up of dead cells scatters light instead of reflecting it, and dehydrated skin makes it worse. Smooth the surface, saturate it with water, and brighten tone — glow follows.
Glass skin is a surface condition, not a product. Layer water into damp skin, seal it with a barrier cream, exfoliate gently once or twice a week, and light reflects evenly instead of scattering.
A rosacea routine that helps is short, fragrance-free and consistent. Fewer, gentler steps almost always beat a longer regimen.
A short, consistent routine works remarkably well on thicker, oilier, often-shaved skin. Four steps, twice a day, is enough.
Gentle cleansing and one pore-clearing active handle most teenage skin, even with hormones pushing oil into overdrive. Keep it short and consistent.
Pregnancy brings breakouts, melasma, and new sensitivity just as retinoids come off the table. Azelaic acid, niacinamide, vitamin C, and tinted mineral SPF cover almost all of it safely.
A daily cast-free SPF, gentle actives and no scrubs stop dark marks and melasma before they start. Preventing inflammation matters more than any brightener.
Fair skin has the least natural UV protection, so sun damage drives most visible aging. Protect hard by day, rebuild at night, and introduce actives slowly to avoid lasting redness.
Control shine and clear pores without stripping your barrier.
Rebuild a comfortable moisture barrier with layered hydration.
Balance an oily T-zone and drier cheeks with zone-aware layering.
