You don’t need to stay up to date with the latest buzz in beauty ingredients to notice the meteoric rise in acid-based skincare.
There’s a new generation of products that have been brought to market to coincide with our ever-growing knowledge and interest in what details each and every ingredient list. The emerging skintellectuals have led to transparency in the industry where skin-damaging components that dominated the pre-active offering have been pushed aside in favour of technical, efficacious and science-led line-ups with acids at the heart.
From hyaluronic to azelaic acid, it can feel like there’s a hi-tech name to know each week, which makes it daunting to know where to start. But if you’re just beginning to up the ante of your skincare routine, there is one powerhouse acid you need to have on your radar.
Mandelic acid should be your entry point into the world of chemical exfoliants. The gentler AHA (alpha hydroxy acid) is derived from bitter almonds and takes a less irritating approach to shifting dead skin.
The multitasking ingredient accelerates cell turnover, improves the appearance of hyperpigmentation and helps to unclog pores.
We consulted Dr Kemi Fabusiwa (@dr.fab), junior doctor and skincare expert for the INKEY List to decode mandelic acid.
What does mandelic acid do?
“Mandelic acid is an alpha-hydroxy acid which can be found in any different types of products such as serums, blemish-treatments and peels. It increases cellular turnover by removing the upper layer of dead and dying skin cells,which allows your younger healthier cells to come to the surface. Mandelic acid is larger in molecular size than other AHAs like glycolic acid, which means that it can exfoliate the skin without penetrating too deep. This makes mandelic acid a great option for those in need of gentle exfoliation.”
What should you use mandelic acid for?
“Alpha hydroxy acids such as mandelic acid are able to exfoliate the skin and remove older skin cells. Due to this, they can help to exfoliate old skin cells that are congesting the pores which makes it great for breakouts and acne. But it can also help to remove areas of hyperpigmented skin for those wanting a more even skin tone.”
What skin type does mandelic acid work well for?
“Mandelic acid is a universal ingredient that can work well for individuals with oily or dry skin. Due to its large molecular size, it is also suitable for individuals with hypersensitive skin types.”
What ingredients does mandelic acid work well with?
“Mandelic acid works nicely in conjunction with ingredients like niacinamide and salicylic acid. It is important to always look out for signs of inflammation (redness, swelling, warmth, irritation) when combining actives. But it has a nice synergistic effect with other anti-acne ingredients.”
What type of products does mandelic acid work best in?
“Mandelic acid is an exfoliating acid, which means that it works nicely in serums, skin peels and blemish treatments. It can also be left on overnight in some formulations.”
