A first-step essence that helps skin look smoother and healthier
Biotherm Life Plankton Essence is a regenerating water serum, or essence, for all skin types, used right after cleansing as the first step of the routine. It is built around Life Plankton, Biotherm's signature ingredient obtained from a thermal-spring micro-organism, known for its regenerating benefits, together with hyaluronic acid and glycerin that hydrate the skin. Its water-light texture prepares the skin for the next steps. With daily use, the skin feels smoother and more supple, and looks more even and radiant.
The texture
A clear, watery liquid, lighter than a serum. It sinks in almost instantly and leaves the skin fresh and slightly plumped, ready for serum and cream.
Who it suits
- All skin types, including combination skin
- Dull, tired-looking skin
- Anyone wanting a lightweight hydrating first step
- People using the Life Plankton serum or elixir
Worth knowing before you buy: This essence is scented and contains fragrance allergens (linalool, limonene, geraniol and others), so very sensitive skin may prefer a fragrance-free hydrating lotion. It is a first step, not a complete moisturiser.
How long one bottle lasts
Used morning and evening with a few drops each time, the 125ml bottle lasts around two to three months.
