PIH is what happens when skin gets inflamed and then leaves a stain behind. The original trigger can be acne, a rash, a burn, an aggressive peel, friction, or even one badly timed extraction. The skin responds to injury by sending inflammatory signals to pigment-producing cells, called melanocytes. Those cells can overproduce melanin, which leaves a brown, grey-brown, or reddish-brown mark after the bump or irritation is gone. Very rude. Very common. The important distinction: PIH is colour, not a dent. If the skin is flat but darker, that is pigment. If there is a hollow, pit, raised edge, or changed texture, that is scarring or texture damage. The two can happen together, which is why acne recovery can feel endless: the spot goes down, then the mark moves in like it pays rent. Medium, pigment-prone skin tends to show PIH more stubbornly because melanocytes are more reactive. Sun exposure, heat, picking, over-exfoliation, and using too many strong actives at once can all keep the pigment cycle switched on. The most useful approach is boring but effective: reduce new inflammation, protect from UV every day, and use pigment-regulating ingredients consistently without irritating the skin into making more marks.

Find Your Cause

Not every cause is treated the same way — find the one that matches you.

Acne and breakouts

Inflamed spots can trigger pigment cells to overproduce melanin, especially if the spot is deep or repeatedly irritated.

This one's more about routine than a specific product — gentler handling helps more than any ingredient.

Picking or squeezing

Mechanical trauma adds a second injury on top of the original breakout, which can deepen or prolong the mark.

This one's more about routine than a specific product — gentler handling helps more than any ingredient.

Aggressive exfoliation

Too many acids, peels, or scrubs can inflame the skin and keep pigment production active.

This one's more about routine than a specific product — gentler handling helps more than any ingredient.

UV exposure

Sunlight can darken existing marks and make fading slower, even when the original inflammation is gone.

Heat and friction

Heat, rubbing, tight masks, and repeated irritation can keep pigment-prone skin reactive."
