If you’ve ever been happy with a disappeared pimple, only to be greeted with the dark spot where it used to be, welcome to the acne + pigmentation cycle no one warned you about!
Did you know acne and pigmentation, both are closely connected. And they frequently occur together. The pigmentation that occurs post the breakout is Post-Inflammatory Pigmentation (PIH).
Getting rid of acne is only half the battle. What it leaves behind can stick around for months, sometimes even longer. But guess what, you don’t have to treat them separately. With the right routine, you can address them both at the same time.
What Causes Acne Pigmentation?
Post-Inflammatory Hyperpigmentation (PIH)
The pigmentation that occurs post the breakout is Post Inflammatory Hyperpigmentation (PIH). When an acne lesion forms, it causes significant inflammation in the skin. As a response to this inflammation, your body’s immune system triggers melanocytes (pigment producing cells), as a natural defence mechanism, into overdrive. Due to this, the cells produce excess melanin. Once the pimple is healed, it leaves behind a flat,dark mark or red spots. This is PIH.
Sometimes, a healing pimple can still be swollen, while the pigment cells in the exact same spot have already started darkening.
This is all the more evident on Indian and darker skin tones, where melanocytes are more reactive.
The difference between scarring and PIH
-
Its fundamental difference is purely just a colour change.
-
Acne scarring causes actual changes to the skin’s structure such as piling, rolling or raised tissue. It needs targeted treatments and often dermatologist intervention.
-
PIH on the other hand, can fade with the right skincare and consistency.
-
Managing skin barrier health is the most critical factor, when it comes to both acne and pigmentation. When you have acne and pigmentation, your skin barrier which is the outermost layer that absorbs moisture and keeps irritants out, is compromised.
Best Ingredients for Acne + Pigmentation
Salicylic Acid
-
A BHA that is oil soluble, meaning it dissolves in lipids and oils, sinking deep into your pores. It can cut through sebum to clear dead skin, dirt and impurities and oil, and unclog pores from within.
-
It has anti-inflammatory properties which help reduce inflammation and prevents further breakouts
-
It is regarded the gold standard in treating mild acne (blackheads,whiteheads) and active acne scars
Niacinamide
-
Niacinamide (Vitamin B3) serums for acne help control sebum production
-
It inhibits the transfer of melanin to skin cells, helping fade dark spots faster as it stops it from showing up on the skin’s surface (National Library of Medicine).
Azelaic Acid
Considered one of the most versatile, multitasking ingredients.
-
Helps target acne and pigmentation simultaneously
-
Helps reduce acne causing bacteria,
-
Reduces inflammation and redness
-
Targets post-acne discolouration
Retinol
-
It accelerates cell turnover (pigmented cells shed faster, making pigmentation fade faster).
-
They improve uneven skin texture
-
Keep pores clearer over time by preventing dead skin buildup
-
It is best used at night and should always be paired with an SPF during the day.
-
Beginners should start introducing retinol twice a week,building gradually from there.
Vitamin C
-
Brightens post-acne marks
-
Inhibits tyrosinase, the pigment producing enzyme, fading existing dark spots over time
-
Proven brightening agent with potent antioxidant protection, meaning it provides protection against environmental damage such as UV & pollution.
-
Boosts SPF efficacy, making it a bonus for pigmentation- prone skin
Simple Skincare Routine for Acne-Prone Pigmented Skin
Morning Routine
-
Gentle cleanser: Such as Deconstruct’s Salicylic Acid Face Wash to effectively remove buildup and excess sebum(oil)
-
Antioxidant serum: Such as Deconstruct’s Vitamin C Serum to reduce oxidative stress and environmental damage, while also protecting your skin against UV- induced pigmentation and dark spots
-
Moisturizer: Using a lightweight hydrating moisturizer with non-comedogenic ingredients to not clog your pores
-
Sunscreen (most crucial step): A broad-spectrum SPF 50+ sunscreen for effective UV protection
UV acts as a fuel for acne and pigmentation marks. When UV light hits unprotected skin, it triggers your melanin producing cells (melanocytes) into overdrive as a natural defence against UV. So SPF is a non-negotiable for acne and pigmentation!
Night Routine
-
Gentle cleanse: Wash away your SPF, pollution and excess oil
-
Acne treatment: Use ingredients like salicylic acid and niacinamide, azelaic acid, retinol, depending on your skin type

Common Skincare Mistakes
-
Picking pimples: It deepens inflammation causing PIH, guarantees a dark mark

-
Skipping sunscreen: Can promote UV-induced darkening and make pigmentation, dark spots and acne marks worse
-
Using too many active ingredients: Can trigger skin sensitivity and increase chances of further breakouts + melanin overproduction, causing more pigmentation
