Lactobionic acid is a sugar acid and is part of the family of polyhydroxy acids. Lactobionic acid has similar effects to alphahydroxy acids such as glycolic acid but is associated with less sensitivity than AHAs. Lactobionic acid is used to treat photoaging, due to its large molecular size and slower penetration rate. Due to its powerful humectant and anti-ageing properties, it is widely used in skincare formulations.
1. Gentle exfoliation
As lactobionic acid expedites cellular turnover, lactobionic acid can help refine skin texture and minimise the appearance of fine lines, wrinkles and enlarged pores, and promote a more luminous and even skin tone for all skin types. It also aids in diminishing scars and hyperpigmentation. It doesn’t penetrate the skin too deeply and exfoliates only the upper layers, which makes it gentle enough for sensitive skin.
2. Healthy hydration
Lactobionic acid is a powerful humectant that helps the skin to attract and retain moisture. It also encourages the production of elastin and collagen, which help skin to remain better hydrated.
3. Antioxidant protection
Lactobionic acid is an antioxidant that absorbs environmental stressors such as free radicals. A study found that lactobionic acid may also help to suppress matrix metalloproteinase (MMP) enzymatic activity, and therefore can help to protect against any further sun damage.
Lactobionic acid is compatible with all skin types. It is particularly recommended for use on sensitive skin.
Lactobionic acid works well in combination with most other products, particularly with other acids. It is safe for use alongside many other key actives but should not be used alongside products containing retinol.
You can use a product containing lactobionic acid once a day (after cleansing and before applying moisturiser). You should avoid using a retinol product directly afterwards.
