Together, we can make a difference. For each purchase of a Tonic Body Treatment Oil*, Clarins will make a donation to the MIRIAD** research programme. The project studies the influence that diet and the environment might have on inflammation linked to rheumatic disease. *This oil is a cosmetic product. It does not have any therapeutic effect nor is it a treatment for arthritis. **MIcrobiome Research Initiative on spondyloArthritis and Disbyosis.
