How to Get Rid of Blemishes

THE PROBLEM

Excess oil production creates a breeding ground for bacteria and leads to clogged pores. Fend off breakouts by using a cleanser with salicylic acid; it will control greasiness as it exfoliates, so pores are less likely to get blocked. To zap existing pimples, apply a 10 percent benzoyl peroxide treatment. Though it can be drying, most people at this age can handle the maximum strength.

THE PROBLEM

Skin-cell turnover begins to slow down; as a result, dull flakes get trapped deep inside pores. Manual exfoliation can help flush out your pores to keep skin smooth, while gentle, sulfur-based treatments dry out pimples without irritating your complexion.

THE PROBLEM

As estrogen levels decrease, testosterone takes over, which can trigger acne flare-ups. Collagen production also diminishes, causing skin to become thinner and more vulnerable to bacteria. Restore balance and firmness with a moisturizer that contains soy, a phytoestrogen. Treat current blemishes with an exfoliating 2 percent salicylic-acid gel, which is milder than both benzoyl peroxide and sulfur.

THE PROBLEM

Accumulated sun damage breaks down collagen and further weakens skin, making it red, inflamed, and even more susceptible to bacteria. Apply a gradual-release retinol to gently exfoliate and rebuild collagen. Calm blemishes with a mix of salicylic acid and anti-inflammatory ingredients like bisabolol or lycopene.
