How to Fade Acne Marks: Niacinamide, Azelaic Acid & PAD Explained
- by CurePik
If a pimple heals but leaves a brown or red mark behind, you're dealing with post-acne hyperpigmentation — one of the most common skin concerns in India, especially for medium to deep skin tones. The good news: unlike true acne scars, most marks fade with the right ingredients and consistency.
Acne marks vs. acne scars — know the difference
A mark is a flat patch of discolouration (brown, black or red) where a pimple used to be. It sits on the surface and responds well to topical actives. A scar is a change in skin texture — a pit or a raised bump — caused by deeper damage, and usually needs in-clinic treatment. This guide is about marks.
The ingredients that actually fade marks
Niacinamide
A form of vitamin B3 that helps reduce the look of dark spots, supports the skin barrier and helps control oil. It's gentle, suits most skin types and pairs well with almost everything — a great daily starting point. A 10–12% niacinamide serum is a popular choice.
Azelaic acid & PAD (potassium azeloyl diglycinate)
Azelaic acid helps fade pigmentation and calm acne-prone skin at the same time. PAD is a gentler, more soluble derivative often found alongside niacinamide in brightening serums — a good option if stronger acids irritate you.
Vitamin C
An antioxidant that helps brighten overall tone and fade marks while protecting skin from daily damage. Best used in the morning, followed by sunscreen.
Alpha arbutin & kojic acid
Both target the pigment-making process to help lighten stubborn spots. They work well layered with niacinamide for uneven tone and melasma-type pigmentation.
A simple routine to fade marks
Morning: gentle cleanser → vitamin C or niacinamide serum → moisturiser → sunscreen SPF 50.
Night: cleanser → niacinamide or azelaic/PAD serum → moisturiser.
Introduce one new active at a time, give it 4–6 weeks, and don't mix too many strong acids at once.
The step most people skip: sunscreen
Sun exposure darkens existing marks and undoes weeks of progress. Daily SPF 50 PA+++ is non-negotiable if you actually want marks to fade — see our guide to sunscreens for oily and acne-prone skin.
How long does it take?
Surface marks often start improving in 4–8 weeks; deeper or older pigmentation can take 3–6 months of consistent use. Patience and daily sunscreen matter more than any single product.
