Biotherm and thermal plankton
Between the 1940s and 1950s, the physician Jos Jullien studied a substance rising to the surface of the waters at Molitg-les-Bains, a thermal plankton, and together with Jeanine Marissal looked for a way to use it in a cosmetic formula. That research gave rise to the brand in 1952. Today the house's exclusive ingredient is Life Plankton™, a probiotic fraction found in many of the formulas in the range, from face sunscreen to body lotion.
The lines in the range

The Lait Corporel Anti-Desséchant is the house's everyday lotion, designed for flaky skin and to restore its protective barrier, with a texture that is neither greasy nor sticky. For dry skin that has lost its radiance there is the Oil Therapy Baume Corps, a nourishing balm with rosehip, passionflower and apricot oils. For firmness, the house offers the Collagen Fit Firming Body Milk and the Life Plankton Body Milk. For rough-textured skin there is the Biocorps line, with a weekly scrub and a chemical peel serum.

Scented waters
Among the scented waters, Eau Pure is aromatic and fruity, with lime, kiwi and green tea; Eau d'Energie is fruity with apricot.

How to choose a body lotion from the range
For dry, dull skin, the Oil Therapy Baume Corps is a good place to start. If the skin is rough, with small thickened patches, use the Biocorps scrub once a week and the Biocorps serum every day. For a lightly scented body, choose the Eau Pure, Eau d'Energie or Eau Vitaminée body lotions, the latter with grapefruit, sweet orange and freesia.
Sizes and gift sets
The Lait Corporel Anti-Desséchant and the Oil Therapy Baume Corps also come as a 400 ml + 400 ml duo. The Duo Detersione Viso pairs the Biosource cleansing milk and toner. The Eau Pure set combines the eau de toilette and the shower gel.
