i. This ingredient slows shedding of cells inside the hair follicles, which prevents the pores from clogging. It may also break down whiteheads (clogged pores that have no opening) and blackheads (pores that are open and have a dark surface). Salicylic acid can cause mild stinging and skin irritation. OTC acne products are available with 0.5 percent to 2 percent salicylic acid.
ii. E.g.,
• Sulfur and resorcinol.
iRarely used alone, sulfur and resorcinol are often found together in acne products. These ingredients remove dead skin cells that clog pores and help remove excess oil. They may also break down whiteheads and blackheads. Sulfur and resorcinol can cause redness and peeling, which may occur several days after using the product.

6. What are the other advice can you give her when she is using acne treatment product?

•Avoid oily cosmetics, sunscreens and hair products. Instead use products labeled "oil-free" or "noncomedogenic," which means they won't clog pores.
•Wash problem areas twice daily with a non medicated soap or mild cleanser. But don't overdo it. Excessive washing and scrubbing can worsen acne.
•Apply just enough acne product to cover the problem areas.
•Use an oil-free, water-based moisturizer to help alleviate dry, peeling skin.
•Don't pick or squeeze blemishes. Infection or scarring may result.
