L'Oreal Paris Anti-Aging Skin Care Kit comes with 2 Revitalift favorites. Derm Intensives Hyaluronic Acid Facial Serum and Triple Power Day Cream Face Moisturizer. A dermatologist validated, highly-concentrated, anti-aging plumping hyaluronic acid serum that immediately hydrates and fills wrinkles in 2 weeks. What Does Hyaluronic Acid Do? Hyaluronic Acid is naturally produced by our bodies and plays a critical role in skin’s youthful look. It’s natural production rapidly decreases as early late 20’s and must be topically supplied as a key step after cleansing. Hyaluronic Acid is a dermatologist-recommended ingredient that attracts a high level of moisture. It’s a big molecule and therefore needs to be adapted to be absorbed by the skin in order to be effective. The formula has been designed to provide a dual plumping and hydration effect by combining hyaluronic acid of both high and low molecular weight. 0.5% High Molecular Weight Hyaluronic Acid will remain on top of the skin, without a tacky feeling, to help lock-in moisture for dewy-looking skin. 1% Low Molecular Weight Hyaluronic Acid absorbs more easily to help smooth skin texture and instantly replump skin. This formula has also been developed and tested to be safe for sensitive skin. What is Revitalift Triple Power Day Cream? It is an anti-aging face moisturizer that visibly Reduces wrinkles, firms and brightens skin in 1 week. We recently improved our formula with new ingredients, and a new fragrance and texture for better results. How to Use: After cleansing, hyaluronic acid should be the immediate next step before any other treatments or moisturizers. Every morning and evening, apply 2-3 drops to the face and neck, avoiding the eye area. For best results, use with Revitalift Triple Power Day Cream.
