The different types of chemical peels

Don't worry, we'll explain what each type of peel is, what it can do for your skin, and how it can help you achieve your beauty goals.

Alpha Hydroxy Acids (AHAs)

Alpha hydroxy acids (AHAs) are natural organic acids derived from fruits such as citrus fruits, apples, grapes and cranberries. They are used to exfoliate the skin by removing dead cells from the top layer, which stimulates cell regeneration and helps reduce the appearance of fine lines, age spots and spots. acne scars.

Alpha-Hydroxy AHA Chemical Peel

AHAs are often used to treat dry, dull skin, as they have moisturizing properties that help retain moisture in the skin. They are also useful for treating oily skin and enlarged pores, as they can help loosen impurities and excess oil.

There are several types of AHAs, including glycolic acid, lactic acid, citric acid, and malic acid. Glycolic acid is most commonly used because it has the smallest molecule, which allows it to penetrate the skin more easily.

AHA peels are generally mild and does not require recovery time. However, they can cause mild skin irritation, so it is important to use them with care and follow the instructions of the product or your esthetician.

If you have sensitive skin, we will recommend a low-concentration AHA peel or we will opt for another type of chemical peel.

Beta-hydroxy acids (BHA)

Beta hydroxy acids (BHA) are salicylic acids, derived from salicylic acid, a compound derived from willow bark. They are often used to treat skin problems such as acne, blackheads and enlarged pores.

BHAs have a similar molecular structure to AHAs, but they have a larger molecular size which makes them less irritating to the skin. They also have anti-inflammatory properties that can help reduce acne inflammation.

Beta-Hydroxy BHA Chemical Peel

BHA peels can help exfoliate the skin by removing dead cells from the top layer, which can improve skin texture and clarity. BHAs are particularly useful for oily and acne-prone skin as they can penetrate deep into the pores to dislodge impurities and excess oil.

However, BHAs can cause mild skin irritation, especially for sensitive skin. It is important to follow the product instructions and not to use BHA peels more often than recommended.

If you have sensitive skin or have allergies to aspirin, it's best not to use BHA peels. In this case, it is recommended to opt for another type of chemical peel or to consult a beauty professional for personalized advice.

Trichloroacetic acid (TCA)

Trichloroacetic acid (TCA) is an organic acid commonly used for medium and deep peels. It is often used to treat wrinkles, acne scars, age spots and skin blemishes.

TCA peels are more powerful than AHA and BHA peels and can cause severe peeling of the skin for several days. TCA peels are often used for mature or sun-damaged skin, as they can help stimulate collagen production and reduce the appearance of fine lines and wrinkles.

TCA trichloroacetic chemical peel

However, TCA peels are not suitable for all skin types as they can cause side effects such as redness, crusting and severe flaking. They may also not be recommended for dark skin tones as they can cause hyperpigmentation.

If you opt for a TCA chemical peel, it is imperative to follow the instructions of your esthetician carefully, and in particular to protect your skin from the sun during the recovery period. The use of appropriate care products is necessary to help speed up the healing process.

PRX-T33 is the revolutionary new generation of biorevitalizing TCA peel, used to correct face lift scars, stretch marks and sagging skin.

This intense stimulation creates immediate hydration, firmness and firming of the skin while leaving the top layer of skin intact.

This non-peeling peel is particularly suitable for active individuals who want to maintain a perfect image at all times.




Phenol is a powerful acid used for deep chemical peels. Phenol peels are often used to treat deep wrinkles, acne scars, age spots and pre-cancerous lesions.

Phenol penetrates deep into the skin to slough off dead cells from the top layer, stimulating the production of collagen and elastin for firmer, younger-looking skin. Phenol peels have long-lasting results and can dramatically improve the appearance of the skin.

However, phenol peels are the most aggressive of the chemical peels and can cause serious side effects such as pain, burning, crusting, severe scaling and depigmentation of the skin. Phenol peels should only be performed by trained professionals in a medical environment.

Phenol peels are generally reserved for people with serious skin problems and are not recommended for dark skin due to an increased risk of permanent depigmentation. They also require a longer recovery period and rigorous sun protection for several months after treatment.

Dangers and contraindications of chemical peels

In this section, we'll discuss the dangers and contraindications of chemical peels, as well as steps you can take to minimize the risks and get the most benefits from chemical peels.

Risk of irritation and burns

Chemical peels can cause skin irritation, especially for sensitive skin. Alpha hydroxy acid (AHA) and beta hydroxy acid (BHA) peels are generally gentler and have less chance of irritation than stronger chemical peels like phenol. However, it is important to follow the instructions of the product or your esthetician and test the product on a small area of skin before using it on the whole face.

Dangers and contraindications chemical peel

Chemical peels can also cause chemical burns if used improperly or left on the skin for too long.

Contraindications for chemical peeling

Although chemical peels can be beneficial for many people, there are some contraindications that should be considered before proceeding with treatment.

Chemical peels are not recommended for people with a history of skin conditions such as eczema, psoriasis or lupus, as well as people with skin lesions, infections or rashes. Chemical peels can make these conditions worse and cause pain or complications.
