“Acne scars” cover two very different things, and it’s worth being honest about which is which. Flat dark or red marks left after a breakout — post-inflammatory hyperpigmentation or erythema — often fade over time and respond to tone-evening skincare. True textured scars (pitted or raised) are changes in the skin’s structure that topical products generally can’t flatten; those are best assessed by a dermatologist, who may suggest in-clinic options. For the marks skincare can help, the single most important daily step is sunscreen, since UV makes discolouration darker and more stubborn. Below are the product types people reach for, with honest notes. Patch test, and see a dermatologist for raised, pitted or spreading scarring.
