Got dark spots after a breakout? Post-acne hyperpigmentation (PIH) happens when skin makes extra pigment while healing. Good news: most marks improve with the right routine and a little patience. Below are clear, practical steps you can start today.
Sun protection is the single biggest thing that speeds fading. Use a broad-spectrum sunscreen SPF 30 or higher every morning, and reapply if you’re outside. Sunscreen stops existing marks from getting darker and prevents new ones. Next, keep your cleanse–treat–moisturize routine simple: a gentle cleanser, a targeted treatment for PIH, and a non-irritating moisturizer. Avoid scrubbing or strong physical exfoliants that can inflame skin and worsen pigment.
Try these easy, effective actives: azelaic acid (10–20%) reduces pigment and calms acne; niacinamide (2–5%) lightens spots and strengthens the skin barrier; vitamin C (10–20%) brightens and protects against future sun damage. Introduce one product at a time and patch-test for irritation.
Topical retinoids (adapalene or tretinoin) help by speeding cell turnover and fading pigment. Use them at night and pair with moisturizer to reduce dryness. Hydroquinone is a strong brightener often used short-term (2–4%) under a doctor’s guidance; it works fast but needs careful use. Chemical exfoliants like glycolic acid or low-strength salicylic acid can help, but don’t overdo them—2–3 times a week is enough for many people.
Professional options work faster but cost more: medical chemical peels, microneedling, and certain lasers can significantly reduce PIH in fewer sessions. These are best for stubborn marks and should be done by a licensed dermatologist or aesthetician who has experience treating darker skin tones—wrong settings can make pigmentation worse.
Important do’s and don’ts: don’t pick or pop pimples; that pushes pigment deeper and prolongs fading. Always patch-test new actives. If you have darker skin, be conservative with aggressive treatments and ask for a provider skilled in treating hyperpigmentation in your skin type.
How long until you see change? Mild PIH can fade in 2–4 months with consistent care. Stubborn spots may take 6–12 months or longer. Combining sunscreen, a brightening topical, and a retinoid usually gives the best results without risking more damage.
If marks get worse, spread, or you’re unsure about a product, see a dermatologist. They can suggest prescription options and safe in-office treatments tailored to your skin.

As someone who has struggled with acne, I've discovered the incredible role benzoyl peroxide can play in treating post-acne hyperpigmentation. This powerful agent not only fights acne-causing bacteria, but also helps to fade those stubborn dark spots left behind. By increasing cell turnover, benzoyl peroxide encourages the skin to heal, revealing a more even complexion. However, it's essential to use it cautiously and follow the recommended guidelines to avoid irritation or further skin damage. Overall, incorporating benzoyl peroxide into my skincare routine has been a game changer in helping me achieve clearer, more radiant skin.
