The BIODROGA Medical Institute SKIN BOOSTER are designed as problem solvers for the most intensive effect and a lasting improvement in the skin's condition. In each of the serums, high-tech active ingredients such as peptides, vitamins or antioxidants work together with a specially selected acid. The combination of powerful active ingredients such as 20% niacinamide, 1% retinol, 5% AHA acid or peptides and acids are the key to maximum effectiveness. The type and properties of the integrated acid, for example hyaluronic acid, ferulic acid, azelaic acid or glycolic acid, its concentration and the pH value of the formulation allow the finest adjustments to the desired mode of action. The formulation of the SKIN BOOSTER with a slightly acidic pH value also strengthens the natural skin barrier and its functions and promotes a healthy skin microbiome.
