What is "MANDELIC ACID" and what does it do?
Role: HUMECTANT
Family: AHA
Comedogenic index: 0
Mandelic acid is a mild alpha-hydroxy acid (AHA), ideal for sensitive skin, with exfoliating and brightening properties.
Benefits of Mandelic Acid
Exfoliation and Skin Brightening
It smoothes uneven skin and evens out the complexion.
Less irritating than glycolic acid, it is suitable for sensitive skin, including those prone to rosacea.
Antibacterial properties and skin repair
Known for its antibacterial properties, this substance is effective against acne.
Useful for reducing post-inflammatory marques, age spots and melasma.
Features and Application
Composition and Light Sensitivity
May be synthetic or derived from almonds.
Light-sensitive, requiring opaque packaging to maintain its effectiveness.
Efficacy and skin tolerance
More tolerable than other AHAs thanks to its larger molecular structure.
Effective in concentrations of 5% or more in products for prolonged use.
Comparison with other AHAs:
Distinctions with Glycolic Acid
Less penetrating and acting mainly on the surface, it is gentler than glycolic acid.
Its large molecular size makes it more suitable for sensitive skin.
Studies and Research
Efficacy in the Treatment of Acne
Studies have shown superior efficacy in the treatment of acne and post-acne scarring compared to glycolic acid treatments.
Effective for reducing pustules, inflammatory nodules and blackheads.
How to use
Product selection and precautions
Choose products with opaque packaging because of their sensitivity to light.
Daily use is recommended up to a concentration of 10%.
Origin: Mandelic acid is an alpha-hydroxy acid (AHA) extracted from bitter almonds. It takes its name from "mandel", the German name for almond.
Main properties: It's an effective exfoliant, although its exfoliating capacity is gentler due to its larger molecular structure compared to glycolic acid. This gives it a slower, more superficial penetration into the skin. As a result, it is generally better tolerated, especially by sensitive skin.
Mandelic acid is a promising, less studied but effective AHA for gentle exfoliation, acne treatment and complexion improvement. It is particularly suitable for problem or sensitive skin.
One point to note:
Mandelic acid is sensitive to light, so opt for products with opaque packaging to guarantee its effectiveness.
