Category: Humectant
Type: Ingredient
Definition: Hyaluronic Acid! It’s one of the main contents of the dermis’ glycosaminoglycans, which retain water. Remember that HA starts to decline from the age of 25! The epidermis loses the principal molecule responsible for binding and retaining water molecules, resulting in loss of skin moisture. Hyaluronic acid has a high molecular weight and is very hydrophilic, this means that it’s attracted to water. It functions as a ‘molecular sponge’ allowing extensive hydration. It also functions as a transdermal delivery system for other activities (like Uber). It is a “giving humectant” meaning that it attracts water, but also forms a film.
Let's Have a Look
Benefits
- Vital to maintain the health of collagen and elastin
- Makes the skin more plump, firm and gives a youthful glow
- Gives the skin a gulp of water, and increases overall hydration
- Reduces the signs of aging, fine lines, and wrinkles
- Aids the skin’s natural barrier functions, allowing the skin to better defend itself against free radical damage
Danger
- Look for HA that has a formulation with “low molecular weight”; otherwise the HA will not be able to penetrate the skin deeply enough to do its job!
- Keep an eye on the ingredients lists, specifically alcohol(s), active botanical ingredients and fragrances -they may contraindicate, or cancel out, the benefits of HA.
Hint
A 70 kg adult has about 15 g of HA in her body, and half of it is in the skin.
