This concentrate has been formulated to act directly on the first signs of aging, helping to prevent and correct five common types of expression lines: forehead, fine lines on the forehead, eye contour, crows feet wrinkles and nasolabial folds. Its light, fast-absorbing texture works deep into the skin to improve elasticity, smooth the skins surface and provide a younger, rested appearance. With continued use, the skin regains its firmness, smoothness and a visibly rejuvenated appearance. Instructions for use Apply morning and evening to clean, dry skin. Place a few drops on fingertips and gently massage into areas with fine lines until completely absorbed. Can be used alone or before your regular moisturizer.
