Hyaluronic acid is literally a drink of water for your skin. I choose Tuel’s Hydrate as my Hyaluronic acid. As you use this serum, fines lines and wrinkles will be minimized, giving your skin a smoother more youthful look. Tuel’s Hydrate(Hyaluronic Acid) is 100% vegan. It is free of phthalates, sulfates, parabens, mineral oil, synthetic dyes or fragrances. I recommend using this serum in your morning and evening skincare regimens. In the morning always follow with your SPF 30 sunscreen and in the evening chase it with your favorite Tuel nighttime moisturizer.
