It is important to use Lotion P50 after cleansing the skin with a milk cleanser that respects the pH and barrier of the skin. The first week, add a few drops of Lotion P50 to a cotton pad pre-dampened with water then gently pat/press over face, neck and decolletage in ascending movements.

On subsequent days, a dry cotton pad should be used. If tingling is felt as the skin’s pH is balancing itself, some Biologique Recherche L’Eauxygénante misted over the face will alleviate it.

Work up to using Lotion P50 directly onto dry cotton pads twice a day. May be used morning and night once you skin has fully adjusted.

Not recommended for use in conjunction with a foaming cleanser, retinoids or other exfoliating products.
