Why can acne be worse in adulthood than the teenage years?
It’s really random, though sometimes it's more hormonal. The reason it seems worse is that the majority of adults are not expecting it the way they were at 13.
Do at-home remedies or over-the-counter treatments really work?
Some that work well are topical salicylic acid as a spot treatment and benzoyl peroxide as a wash.
I have heard before that acne on the chin is hormonal. Is this true? If so, what does acne on this and other areas of the face — like the cheeks, forehead, and mouth area — indicate?
Acne on the chin and jawline is hormonal, but there is no other area with that type of correlation.
How can we reduce the appearance of acne scars and red marks left behind by acne?
Stop picking at the acne and that will reduce the chances of scarring. Make sure you also use daily sunscreen — or if it’s enough of an issue for you to seek professional assistance, your doctor can use lasers to diminish their appearance.
What's the best way to safely get rid of blackheads and whiteheads?
Biore strips work well. You can also warm the skin and then gently exfoliate.
