> The serum is to be used preferably in the evening, after removing make-up from your face and the application of a toner or a lotion. At first, apply it 2 to 3 times a week, one drop on each cheek.
> Take a few drops of serum with the supplied pipette (do not dip your fingers or other instruments in the bottle, vitamin C is fragile!)
> Apply by tapping onto entire face, avoiding the eye contour
> Once absorbed into the skin, continue with your usual routine of care
> The sheet mask is to be used 1 to 3 times a week, after cleansing the skin. Follow the application with a serum for optimal action.

Smoochy tip: do not forget to use sunscreen the day after applying your serum as vitamin C increases the photo-sensitivity of the skin!

For a good preservation of care By Wishtrend, we recommend that you store them away from heat, if possible in the refrigerator, and away from light to avoid oxidation of vitamin C. If redness appears, we recommend that you stop using. Keep out of reach of children.

Excellent produit! Ma peau est plus nette et a moins d'imperfections. Je ne l'ai pas encore assez utilisé pour en dire plus mais j'en suis ravie pour le moment. Très contente aussi de Korean smooch, rarement déçu des produits, l'explication de leur utilisation apporte un grand plus!

Les masques sont excellents. À confirmer pour le sérum après plusieurs semaines d'utilisation.

J´ai une peau mate, mixte à grasse avec des périodes de désydratation. Chaque bouton laisse une tache pigmentaire qui prend du temps à partir.cela fait plus de six mois que j´ai adopté Ost ( sérum-masque-crème ) pour ma routine du soir et le résultat à long terme m´est plus que satisfaisant. Je ne compte pas changer.
