Hydroxy acids are a family of acids including AHA, BHA, and PHA, which differ in their properties and tolerability.
A family of acids including AHA, BHA, and PHA, which differ in their properties and tolerability. In cosmetology and trichology, the meaning of this term always depends on the context: location of occurrence, symptoms, duration of the problem, products used, and individual tolerance.
Understanding the term helps to better comprehend cosmetic descriptions, specialist recommendations, and mechanisms occurring in the skin or hair. However, it does not mean that identifying a single element on its own is sufficient to select a therapy.
It is not worth evaluating a product, ingredient, or procedure solely based on the popularity of the term. Formulation, concentration, method of use, contraindications, and skin condition are all important. Introduce changes one by one and observe the reaction.
If the problem is severe, recurring, causes pain, intense itching, inflammation, sudden hair loss, or a significant change in skin appearance, consult a dermatologist. A cosmetologist or trichologist can support care and refer you to the appropriate specialist.
