AHA, BHA & PHA Peels

chemical peels


What are AHA, BHA and PHA peels? 

Hydroxy acids are exfoliants, which are exfoliating substances, characterized by very comprehensive care. They regulate cell renewal, moisturize and tighten the skin, help fight wrinkles, acne and also eliminate sunburn.

Hydroxy acids are divided into three groups: alpha hydroxy acids (AHA), beta hydroxy acids (BHA) and polyhydroxy acids (PHA). They are mainly obtained from natural sources such as plants, fruits or milk. Acids of the first group, the AHA, have the strongest effect, so their use is associated with the highest risk of irritation, but also the most visible rejuvenating and cleansing effects. The mildest are the PHA group, which are great for beginners who want to refresh and moisturize their skin. For people suffering from acne it is recommended to do either  BHA and AHA acids.

The basic principle of acid care is caution. Some of them can act very strongly and cause side effects in the form of irritations, baking or drying of the skin.


AHA (alpha hydroxy acids) are acids derived from fruits, nuts, milk or sugars. They are hydrophilic  (attracted to water) and break down the bonds between cells (desmosomes) to allow for easier exfoliation. 

Acne treatments using AHA are recommended mainly for people with mature or acne skin. Regularly done treatments will moisturize, improve skin elasticity, brighten hyperpigmentation and eliminate wrinkles and other signs of skin photoaging. Higher concentrations of these acids help in the fight against onerous acne, but due to the risk of irritation not everyone can use them. Avoid AHA acid if you have a very sensitive skin.


BHA (beta hydroxy acids), the most common of which is salicylic acid, is derived from willow tree bark, wintergreen oil or sweet birch. Because salicylic acid is lipophilic (attracted to oil) and keratolytic, it is able to penetrate the oils in the skin and clear out follicles of excess debris and skin cells, making it especially effective in  the treatment of acneic skin conditions.

It has the ability to penetrate sebum and act on the deep layers of the skin. It is characterized by strong exfoliating, anti-acne and antibacterial activity. It unclogs pores and cleanses hair follicles and removes blackheads. Salicylic acid is definitely milder than AHA acids and causes less side effects.


PHA (poly hydroxy acids) function the same as AHA, but cause less irritation due to their larger molecular size. They are especially beneficial in treating sensitive skin types that may not be able to tolerate AHA.  They provide anti-inflammatory and antioxidant benefits as well as assist with exfoliation. They do not irritate, cause redness, bake or dry skin. The use of PHA acids will result in the refreshment and cleansing of the skin, as well as its hydration and firming.



In acid care, the season is of great importance. Due to the photosensitizing properties of the acids, they should not be used during the summer when the skin is very exposed to the sun. During the peeling process new skin appears, which is very delicate and susceptible to sunburn and discoloration. Acid care even during other seasons must be supplemented by the use of high sunscreens. The treatment should be performed in a series of 4-6 treatments every 7-10-15 days. A minimum of 7-day skin preparation with AHA acids used by the customer at home overnight. The treatment is recommended especially in autumn and spring, or in winter if there is no strong frost, with UV protection.
