Different types of exfoliating skincare acids and who they're best forPosted by Lucy Hitchcock on
Derived from sugar cane, Glycolic is an AHA with the simplest and smallest structure of its kind and arguably the most powerful. Its low molecular weight can easily penetrate the skin with effective results, alongside exfoliating abilities that help shed dead skin cells, leaving the newer, brighter layers on show. The small molecular makeup of Glycolic increases collagen production and leaves you with radiant and firm skin.
Best for: Normal, Combination or Oily skin.
Originally sourced from milk, Lactic acid is known to be more gentle than Glycolic. With a larger molecular make up it has a milder impact on the skin and is perfect for brightening sensitive complexions.
Synthetic versions offer better stability for a vegan – friendly alternative and is less likely to interfere with the PH of your skin than its stronger counterparts.
Best for: Sensitive skin
Salicylic acid is a form of BHA that work on pores, acne prone skin and blackheads. Working on a deeper level, this anti-inflammatory agent can be found in almost every expert spot treatment and products for oily skin. Being oil-soluble themselves (unlike their AHA counterparts), Salicylic acids have a deeper access to the skin that allows them to work on de-clogging pores, removing sebum and oil, all causes of breakouts.
Best for: Oily and blemish-prone skin
The Acid Expert
Here are some of the lesser-known AHAs on the market that can really supercharge your routine when paired with one of the main acid attractions.
Mandelic acid, derived from bitter almonds, accelerates cell turnover whilst exfoliating away dead skin, making fine lines and dull complexions a thing of the past. Mandelic acid reduces the production of sebum, making your face a shine-free zone and helps aid your skin to age-well.
Best for: Spot-prone yet sensitive skin
Sourced from apples, Malic acid is one of the gentler acids out there and an essential in your skincare regime. Touted for its brightening abilities, Malic acid has a larger molecular makeup than Lactic and Glycolic, decreasing its penetration of the skin and making it therefore, a less intense option. At Luneia, we love to team it with Vitamin C for a double brightness boost.
Best for: Skin that lacks radiance
Antioxidant rich and an ingredient that lessening signs of sun damage, this fruit-derived acid is the perfect addition to take your exfoliation game to the next level.
Best for: Oily and more blemish-prone skin
With larger molecules than their alpha-hydroxy counterparts, these acids have a gentler approach with less risk of irritation. With all the benefits of their stronger alternatives, PHAs work slowly on the surface and are great at strengthening the barrier of all skin types. The most common types known by industry insiders are gluconolactone, lactobionic and maltobionic.
Best for: Just about everyone, especially those with sensitive skin.
Derived from yeast, Azeliac acid is proven to be of huge help to rosacea and acne sufferers, largely due to its anti-bacterial and anti-inflammatory qualities. Suitable for use both day and night, just make sure you pair with your favourite moisturiser to minimise any dry patches.
Best for: Acne and Rosacea sufferers.
