A light probiotic serum that helps skin look younger and stronger
Biotherm Life Plankton Elixir is a regenerating anti-aging serum for all skin types and ages. It is built around Life Plankton, a biotech ingredient Biotherm derives from a thermal-spring micro-organism, combined with probiotic fractions to strengthen the skin and support its renewal. Hyaluronic acid, a vitamin C derivative and adenosine complete the formula. Biotherm reports it corrects 10 visible signs of aging, leaving skin smoother, firmer-looking and more radiant.
The texture
A light, silky serum that absorbs straight away and leaves no residue, so it layers easily under any moisturiser.
Who it suits
- First signs of aging and fine lines
- Dull, tired or stressed skin
- All skin types, including combination
Worth knowing before you buy: it contains alcohol and fragrance, so very reactive skin may prefer a fragrance-free serum.
