QUESTION: What are AHA and BHA?

The abbreviations AHA and BHA denote popular types of chemical acids that are actively used in modern cosmetology for effective exfoliation and epidermal renewal. Understanding the differences between them allows you to choose a competent and safe skincare routine that solves specific aesthetic skin tasks without the risk of injuring it.

The category of AHA acids includes water-soluble compounds such as glycolic, lactic, mandelic, and malic acids. They work exclusively on the surface layer of the epidermis, gently dissolving the intercellular bonds of keratinized scales. This stimulates regeneration processes, evens out skin relief, improves complexion, and helps combat hyperpigmentation and post-acne marks.

BHA acid is represented by salicylic acid, which has fat-soluble properties. Thanks to this unique quality, it is able to penetrate deeply and unhindered inside the sebaceous ducts. There it dissolves excess sebum, cleanses pores from impurities, and effectively prevents the appearance of blackheads and inflammatory elements.

The choice of a specific type of acid directly depends on the individual characteristics and needs of your skin. For dry, dull, and aging skin, AHA acids are the ideal choice, returning smoothness and a healthy glow. Owners of oily, problem skin prone to breakouts and acne are better off giving preference to BHA acid for deep pore cleansing.

When introducing acids into your beauty routine, it is important to follow safety rules and not combine them with retinol on the same evening. Such active ingredients when applied simultaneously can cause severe irritation, redness, and damage to the protective barrier. It is better to space them out on different days or use acids in the morning and retinol strictly in the evening, not forgetting the mandatory application of SPF cream.
