Dukesa review for RetinoTightening Ampoule

Main Ingredients: 1. Hydroxypinacolone Retinoate (HPR) (1,000ppm): as a member of the skincare royal family, Hydoxypinacolone Retinoate is able to provide the same results to the skin as retinoic acid when applied, without the irritation associated with 0.5% retinol. 2. Adenosine: decreases the appearance of wrinkles by energizing the skin's surface. 3. Niacinamide: supports the skin barrier (the outer surface of skin), increases its resiiency, and improves texture by making pores look smaller. Cautions: 1. Patch test on the ear lobe before using on your face. 2. Integrate the product slowly and gently into your skincare routine: start off with a pea-sized amount, 2 times per week, slowly increasing the usage after 1-2 weeks to give the skin a chance to acclimate. 3. Watch out for harsh side effects such as itchiness and redness. 4. Use the product only at night and wear sunscreen every day. 5. Don't use this product together with products that contain AHA, BHA.
