BHA
BHA (Beta Hydroxy Acid) is a common ingredient in skincare and cosmetic products. It's primarily used for its exfoliating properties and ability to unclog pores. When reviewing resumes in the cosmetics industry, you'll often see BHA mentioned alongside other skincare ingredients like AHA (Alpha Hydroxy Acid) or Salicylic Acid (which is actually a type of BHA). This ingredient is particularly important in formulations for acne-prone or oily skin products. You might see it referred to as Beta Hydroxy Acid, BHA, or Salicylic Acid in product formulations and job descriptions.
