The formula you chose
CELLULAR ANTI-AGING RESURFACING CONCENTRATE
Smoother, more refined skin texture
Smooths and resurfaces with lactic acid.
The texture
A leave-on resurfacing concentrate built on 10% Lactic Acid, an alpha-hydroxy acid that loosens surface corneocyte cohesion at pH 4.0 to 4.2 to help refine the look of texture. This fluid serum smooths the appearance of uneven tone, supported by hydrating Sodium Hyaluronate and antioxidant White Tea and Sage, for photoaged and blemish-prone skin seeking visible renewal.
The study behind it
Lactic Acid is an alpha-hydroxy acid studied in cosmetics for gently exfoliating the skin's surface, supporting a smoother, more even-looking texture.1
- 1 Smith WP. Journal of the American Academy of Dermatology, 1996 (PMID 8784274).
How to use it
- Apply two to three drops to clean skin in the evening, two to three times per week.
- Begin with one application per week and titrate up as tolerated.
- Avoid contact with eyes and lips. Always layer with broad-spectrum SPF 30 or higher daily. AHA leave-on products increase the skin's sensitivity to UV exposure.

Dialled to what your skin tolerates
Exfoliation and masking are the weekly steps in a routine rather than the daily ones. This collection holds both the mechanical and the acid-based options, alongside clay formats that draw down surface residue, so the frequency can be dialled to what the skin tolerates.

Questions
What not to use with lactic acid?
Until your skin is used to this concentrate, avoid using it in the same routine as strong retinoid or BHA (salicylic acid) products, and keep it off broken, irritated or sunburned skin. Lactic acid is an alpha hydroxy acid, which can make skin more sensitive to the sun, so the FDA advises a sunscreen, protective clothing and limited sun exposure while you use it and for a week afterwards.
Is lactic acid good for skin?
Lactic Acid is an alpha-hydroxy acid studied in cosmetics for gently exfoliating the skin's surface, supporting a smoother, more even-looking texture.
How do I use it?
Apply two to three drops to clean skin in the evening, two to three times per week. Begin with one application per week and titrate up as tolerated.
