However, salicylic acid isn’t just for those of us with sensitive skin. It can also help those of you with tougher skin, through higher concentrations. Over-the-counter, you can find salicylic acid in concentrations up to 2 percent, but if you want something even more intense, many spas and dermatology offices offer salicylic acid chemical peels with 20-30 percent salicylic acid. Beware, these peels will likely leave your face very photosensitive for a few days, but they have been known to significantly reduce sebum for a few weeks at a time.
Spot treatments are designed to give problem pimples a mega-dose of concentrated benzoyl peroxide — in a couple of regimens, like the Proactiv Teen Kit, the spot treatment had nearly three times the benzoyl peroxide as its all-over treatment. The logic: If benzoyl peroxide can be irritating to the skin in high concentrations, limiting its intensity to just the pimple itself could save the rest of your healthy skin.
Retinoids – Recommended for people with moderate to severe acne, retinoids can unclog your pores, allowing for your other medicated acne treatments to penetrate deeper. They can reduce your potential for outbreaks and the formation of acne scarring2. You can also use a retinoid cream directly as a treatment after your face cleanse, or even take it in the form of a retinoid pill to treat oil/sebum production and to treat inflammation and acne-causing bacteria.
The dermatologist Dr. Dennis Gross did a major study on water and its effect on skin and he found that the heavy metals in tap water can actually ruin the benefits expensive lotions and serums do for skin. Some cities (New York and L.A., for example) have worse water than others (Seattle, for example). While some dermatologists aren't buying his claims, (Patricia Wexler for one), you can fight the drying effects of water on skin by cleansing with cold cream, a practice common with European women.
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.
