Overview

Underarms are prone to blackheads, according to "Braun-Falco's Dermatology," because they are dark, moist areas in which sebum, the body's natural oil, is trapped all day. When sebum clogs a pore and oxidizes, it turns into a blackhead. Daily treatment of the blackheads under your arms will yield significant results in only a few days, according to "Handbook of Dermatology: A Practical Manual," and you should see full results in six to eight weeks.

Step 1

Splash warm water on your underarms to dilate your pores.

Step 2

Exfoliate your underarms gently with an apricot scrub. According to "Cosmetic Dermatology: Principles and Practice," the apricot scrub will gently remove dead skin cells, promote cell turnover and moisturize the skin.

Step 3

Saturate a cotton ball with witch hazel. Use the cotton ball to apply the witch hazel to the blackheads in your underarms. According to "Braun-Falco's Dermatology," witch hazel is a natural astringent that is gentle enough to be used to treat blackheads in your underarms.
