Maskne is the informal name for breakouts and irritation that show up where a mask sits on the face — usually the cheeks, chin, jawline and around the nose. It happens because fabric rubs the skin, breath and sweat get trapped underneath, and that warm, damp environment disrupts the skin’s normal balance. What exactly is … Read more
Exercise itself does not cause or clear acne. What matters is what happens around the workout — sweat sitting on skin, tight fabric rubbing against the face or back, shared equipment, and how skin is treated afterwards. Movement is generally fine for skin; the details around it are what can tip things one way or … Read more
Yes, sleep can affect skin, but indirectly. Poor or short sleep is linked to higher stress hormone activity, more inflammation, and slower repair — all of which can make existing acne look worse or feel more irritated. Sleep alone does not cause or cure acne, and there is no research showing a fixed number of … Read more
Yes, stress can genuinely affect skin, and the link is not imaginary. Stress hormones can push oil glands to produce more sebum, slow down how quickly skin heals, and disrupt sleep and habits in ways that make existing acne more noticeable. Stress does not create acne from nothing, but it can make an already-present tendency … Read more
Dairy has a plausible but not fully proven link to acne. Some research finds an association between milk — particularly skimmed milk — and breakouts in certain people, likely through its effect on hormones and insulin-like growth factor. It’s not a confirmed cause for everyone, and cutting dairy isn’t a guaranteed fix. Is there actually … Read more
The honest answer is: diet probably plays some role for some people, but it is not the main driver of acne for most, and no food reliably causes or clears it across the board. A few dietary patterns — particularly high-sugar, high-glycemic-index eating — show a modest, inconsistent link in research. Nothing here is settled … Read more
Microneedling is a procedure that uses very fine, short needles to create controlled micro-injuries in the skin’s surface. It’s mainly used to help improve the texture of acne scars, and sometimes for general skin texture or fine lines, by prompting the skin to produce new collagen as it heals. What actually happens during microneedling? A … Read more
Sunscreen doesn’t fade dark marks by itself, but it changes how quickly they fade — or whether they fade at all. UV exposure stimulates the pigment-producing cells that cause post-acne marks to form, so unprotected sun tends to keep marks darker for longer, while consistent sunscreen use lets other fading processes work as intended. What … Read more
The biggest levers are getting inflamed spots calmed down sooner rather than later, leaving them alone while they heal, protecting the skin from sun while a mark is fresh, and asking a doctor about treatment before things become severe. None of this guarantees scar-free skin, but it meaningfully shifts the odds. What actually causes scarring, … Read more
Textured acne scarring — the pitted, uneven kind rather than flat dark marks — can be softened but rarely erased completely. The most effective options are in-office procedures like microneedling, certain lasers, subcision or filler, chosen by a dermatologist based on the specific scar shape. At-home products can help skin quality generally but have limited … Read more
