What is Mandelic Acid Brightening Peel?

The Mandelic Acid Brightening Peel is a gentle, yet powerful alpha-hydroxy acid (AHA) based peel treatment derived from bitter almonds. The Peel’s micro-exfoliating properties helps to accelerate cellular turnover and lift surface impurities, revealing skin that is brighter, firmer and smoother.

At GMA, we call mandelic the trifecta acid because it effectively conquers three top skin concerns: hyperpigmentation, acne and aging.


✔️ A gentle exfoliant that removes dead skin buildup without causing irritation

✔️ Assists with melasma and hyperpigmentation and evens skin tone

✔️ Has antimicrobial and anti-inflammatory properties making it effective against acne, both cystic and comedones

✔️ Promotes collagen production, increases elasticity in the skin, and reduces the appearance of fine lines

✔️ Effective and suitable for all skin types, including sensitive and darker skin types

✔️ The treatment is safe for patients who are pregnant and breastfeeding

The Mandelic Acid Brightening Peel can also be performed on the body as well to promote a more even skin tone in certain areas that may be hyperpigmented such as the underarm and back (typically due to acne). In addition to helping with post inflammatory hyperpigmentation from breakouts, the Mandelic Acid Peel also helps to reduce and control active acne on the body.

suitable for all skin types & ages

While all AHAs, including mandelic acid, dissolve the tiny alkaline bonds between surface dead skin cells that are mature and dehydrated, allowing them to flake off evenly and at a faster rate – mandelic acid does it much gentler. This is because this unique AHA has a slightly larger molecular weight which slows its penetration and absorption into the skin. Slower, more gradual penetration means it is less likely to irritate the skin and produce symptoms associated with more aggressive peels including warmth, redness, stinging and itching.

The gentle nature of Mandelic Acid Brightening Peel makes it safe and effective for all skin types and even for patients with sensitive skin, including skin conditions like rosacea and eczema, as well as darker skin tones who tend to be more prone to post-inflammatory hyperpigmentation.

an enemy of hyperpigmentation

As with other AHAs, mandelic acid works to improve hyperpigmentation by removing surface dead skin cells which also removes the pigment molecules placed in those cells.  When the epidermis undergoes a quicker exfoliative process, the skin’s metabolism will accelerate. The new skin cells that are produced more rapidly will have less pigment placed in them which leads to a brighter, more even complexion.

Having said that, what makes mandelic acid’s brightening properties and its ability to target hyperpigmentation unmatched is again, its gentle nature.  It is typically hard to treat hyperpigmentation and melasma without causing further irritation which could potentially trigger your melanocytes to produce more pigment and thus worsen the discolouration. This is especially true for patients with darker skin tones.

Patients with skin types IV to VI have a higher risk of hyperpigmentation because there is a greater amount of melanin in the skin and their melanocytes tend to be more reactive to skin injury and irritation. That is exactly why we need to be extra cautious when treating patients of higher skin types and careful not to trigger their melanocytes to produce an excess amount of pigment. And the gentle nature of mandelic acid fits this requirement perfectly.

In other words, mandelic’s gentle nature doesn’t make it less effective, but rather, make it a better option and more suitable treatment for discolouration in the skin.
