What is mandelic acid?
Mandelic acid is an alpha hydroxy acid (AHA) derived from bitter almonds used to exfoliate the skin. This skincare ingredient is known to help shed dead skin cells to reveal brighter skin. It is one of the most gentle AHAs and is used to treat skin conditions such as acne, and hyperpigmentation and to revive dull skin.
Mandelic acid vs vitamin C
While both mandelic acid and vitamin C can help get brighter skin, these actives function in very different ways.
Mechanism of action
Mandelic acid’s main action is to loosen the bonds between skin cells found on the top layer of the skin to reveal younger and brighter skin. This exfoliant increases cell turnover resulting in brighter and firmer skin.
Vitamin C, on the other hand, functions both as an antioxidant and tyrosinase inhibitor.
As an antioxidant, vitamin C helps reduce damage caused by free radicals and UV rays to the skin.
As a tyrosinase inhibitor, vitamin C disrupts the formation of melanin in melanocytes (cells where melanin is produced) which in turn renders the transfer of pigment in the skin resulting in brighter skin.
How to use Mandelic acid
Just like every exfoliant mandelic acid is recommended to use at most 3 times a week. Because its role is to boost the skin’s natural renewal process, daily usage can lead to irritation of the skin. It is usually best to use it at night as it increases the skin’s sensitivity to the sun. If you include this exfoliant in your routine make sure to apply sunscreen regularly.
Mandelic acid should not be applied to damaged or broken skin as it should not be used together with other exfoliants and retinoids as this may cause skin irritation. Although it is the most gentle AHA you want to be cautious and start using lower percentages to get your skin used to its effect before increasing the dosage over time.
How to use Vitamin C
Vitamin C is commonly found in serums and other facial treatments and based on the type of vitamin C and its concentration the results it delivers may differ.
Vitamin C-based products can be used on a daily basis but it is most recommended to use them during the day as their antioxidant properties take action the most against free radicals and UV rays.
However, it should be noted that to get the most signified results it is best to go for percentages between 10-15%.
Differences between Mandelic acid and Vitamin C
- The most obvious difference between these two is their categorization. While mandelic acid is an exfoliant, vitamin C is classified as an antioxidant.
- While vitamin C is safe to use on a daily basis, mandelic acid is recommended to use just 3 times a week. Over exfoliation present a risk of irritation to the skin.
- Vitamin C is very unstable and its effectiveness is dosage-dependent. Mandelic acid, on the other hand, is more stable and effective in concentrations as low as 5%.
- Vitamin C can be used both morning and night while mandelic acid is recommended to be used at night.
- Mandelic acid brightens the skin by facilitating the shedding of dead cells. Vitamin C does so by protecting the skin against UV and free radical damage as well as preventing the formation of melanin.
