What does it do?
Lactic Acid is an AHA (Alpha Hydroxy Acid) that gently exfoliates to renew your complexion and strengthen the skin's barrier. It has humectant properties, meaning it helps to draw in moisture to the skin. Lactic Acid is also commonly used as a pH stabiliser. When used for this purpose, it's in a very small dose, meaning it won't impact any sensitivities.
Where does it originate from?
Lactic Acid is commonly derived from milk. However, at Q+A, we use a non-dairy vegetable-derived alternative made from GMO-free maize.
When should I use it?
This ingredient can be used day and night.
What skin type is it best suited to?
When used as a chemical exfoliator, Lactic Acid is a milder alternative to Glycolic Acid and is best suited to more sensitive skin types or people new to AHAs. However, when used as a pH stabiliser, it's suitable for all skin types.
What does it work well with?
Lactic Acid pairs well with Hyaluronic Acid as they both have humectant properties, therefore helping to boost moisture retention in the skin.
What should it not be used with?
You should avoid using Lactic Acid and Retinol in the same routine. Instead use Lactic Acid in the morning or on an alternate night to your Retinol.
What else do I need to know?
AHAs can increase the skin's risk of sunburn so it's important to apply SPF daily and limit sun exposure when using this ingredient..
