1% Hyaluronic Acid Sentinel Serum
1% Hyaluronic Acid Sentinel Serum
Plump, hydrate and protect your skin with my gently-formulated 1% hyaluronic acid serum! This oil-free serum contains both low- (LMW) and high-molecular-weight (HMW) hyaluronic acid that binds a thousand times its weight in water to our skin. There is solid evidence that the application of topical HA of various molecular weights can form films on the skin that will increase moisture, reduce moisture loss, speed up wound healing, reduce inflammation, and decrease the formation of age spots. It softens the skin and restores elasticity to the skin, which can reduce the look of fine lines and wrinkles.
I've included sea kelp bioferment, a soothing and emollient version of seaweed-derived Lactobacillus that offers great oil-free moisture!
If hyaluronic acid is the Michael Jordan of this serum, then niacinamide is Scotty Pippen! Also known as Vitamin B3, studies have shown that niacinamide can increase skin’s keratin, ceramides, and barrier lipids to reduce transepidermal water loss, and boosts collagen synthesis. Niacinamide can also reduce redness, pebblyness, and smooth large pores.
Rounding out the formulation is gotu kola (centella asiatica, or Indian pennywort) supports the healing of minor wounds, and reduces redness, puffiness, and tightness.
pH-balanced to 6 for optimal niacinamide stability. Can be used AM or PM.
Directions: After cleansing and toning, using 4-5 pumps to press gently into skin. Allow to absorb before locking moisture in with your favorite cream.
