pH Balance

Term from Cosmetics industry explained for recruiters

pH Balance refers to how acidic or non-acidic (alkaline) a product is on a scale from 0 to 14. In cosmetics, this is very important because skin and hair have their natural pH levels that need to be maintained. When someone mentions pH Balance in their resume, they're showing they understand how to create or test products that won't irritate skin or damage hair. Think of it like finding the right temperature for a shower - not too hot, not too cold, but just right for comfort and safety. This knowledge is crucial for developing skincare, haircare, and other personal care products.
