Acid

Description

Acid is a fundamental class of skincare ingredients that plays a crucial role in various dermatological treatments and cosmetic formulations. These compounds, characterized by their low pH levels, offer a range of benefits for skin health and appearance. Common acids used in skincare include alpha-hydroxy acids (AHAs) like glycolic and lactic acid, beta-hydroxy acid (BHA) such as salicylic acid, and polyhydroxy acids (PHAs).

Acids primarily function as exfoliants, promoting cell turnover by dissolving the bonds between dead skin cells. This process reveals fresher, smoother skin and can help address concerns like uneven texture, fine lines, and hyperpigmentation. Additionally, certain acids possess anti-inflammatory and antibacterial properties, making them effective in treating acne and reducing sebum production.

The efficacy of acids in skincare formulations depends on factors such as concentration, pH level, and molecular size. Lower concentrations are generally suitable for daily use, while higher concentrations are reserved for professional treatments. It's crucial to introduce acids gradually into a skincare routine and use appropriate sun protection, as these ingredients can increase skin sensitivity to UV radiation. When used correctly, acids can significantly improve skin texture, tone, and overall health.
