Hyaluronic acid is a complex sugar that is usually found between the collagen bundles of the skin.
It is a humectant, this means that it absorbs water from the environment and water from the deeper layers of the skin.
Consequently, it plumps and hydrates the skin. Consequently, hyaluronic acid is less likely to cause side effects or allergic reactions
It can be combined with products that include retinol, vitamin C or AHA/BHA and niacinamide.
applying hyaluronic acid to a dry skin surface simply draws moisture from deeper layers, dehydrating the skin.
Also, you should cover the hyaluronic acid serum with a moisturizer to lock the hyaluronic acid inside,
if the air around you is dry and your skin is dehydrated, HA can absorb water from the deeper layers of the skin.
the best way to use hyaluronic acid is to cleanse your face with a cleanser first, and then apply the hyaluronic acid serum to your damp face to lock in moisture.
