You’ve probably heard of the benefits of retinoid creams for anti-aging, but vitamin A is also efficient at clearing up acne. “[Retinoids] cause skin cells to turn over at a faster rate, decrease oil production, and help skin exfoliate,” board-certified dermatologist Rita Linkner, M.D., tells SELF. Another benefit: Acne is inflammation, and retinoids are anti-inflammatory.
How to Handle It: Speaking of touching, don't! Picking it, squeezing it, or poking at it will only worsen the situation. These may disappear on their own after a few days. Otherwise, Zeichner suggests visiting your dermatologist for a shot of cortisone, which will reduce inflammation and shrink it in just 24 to 48 hours. But if a last-minute appointment isn't in the cards, play mad scientist. First, ice the area, and then apply salicylic acid gel, benzoyl peroxide gel, and 1 percent hydrocortisone cream. The combo will calm skin, kill bacteria, and draw out excess oil from the pimple — all things necessary to take this down, says Zeichner.
Your pimples need TLC, too. The study on acne vulgaris found that, in an attempt to dry out acne lesions, patients often use too many products or apply excessive amounts to problem areas, resulting in further irritation and over drying of the skin. Vigorous scrubbing and using harsh exfoliants can make acne worse by rupturing whiteheads and blackheads, turning them into painful red ones. And remember: no matter how satisfying it is, picking and popping your zits will also increase inflammation and opportunity for infection.
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
