In HLN, Dr Griet Voet assesses ten popular acne treatments and explains when medical treatment is needed.
In HLN, Dr Griet Voet takes a close look at ten popular acne treatments. She explains that acne is an inflammation of the pilosebaceous unit, with blackheads, bumps and spots. It is common among young people, but also affects some adults. Sebum production, hormones and genetics play a role, as do stress, smoking, greasy cosmetics and possibly diet.
Products containing salicylic acid, niacinamide or azelaic acid, among others, can help, while patches and masks are more of an extra. The basis remains mild, consistent skincare and not squeezing spots. For moderate to severe acne, Dr Voet recommends medical treatment via a GP or dermatologist, with patience, as results take a few weeks.
Key advice
Cleanse gently every day and choose products for acne-prone skin.
Don't squeeze spots; it increases the risk of scarring.
See patches and masks as an extra, not a solution.
For moderate to severe acne: seek medical treatment and be patient.
“So you can't prevent acne completely, but you can reduce the chance of flare-ups.” — Dr Griet Voet
