Multi-Form Hyaluronic Acid System
YOUTH LAB. describes Hydro Cloud as combining four hyaluronic acid technologies — three molecular-weight approaches and one bioactive form — to provide hydration at different levels of the skin and help improve the appearance of fine lines and loss of plumpness.
The current INCI includes Sodium Hyaluronate and Sodium Acetylated Hyaluronate, with the complete hydration technology represented within the finished formulation.
Sodium Acetylated Hyaluronate
A modified form of hyaluronic acid with strong moisture-binding properties. It helps support longer-lasting hydration, softness and a smoother, more supple-looking skin surface.
Niacinamide
Vitamin B3 supports barrier function and helps the skin retain moisture more effectively.
It also provides complementary calming, oil-balancing and brightening benefits, making Hydro Cloud particularly useful for combination or oily skin that is nevertheless dehydrated.
Panthenol
Also known as provitamin B5, panthenol helps attract moisture while soothing the skin and supporting barrier recovery.
Betaine
A naturally occurring humectant and osmolyte that helps the skin maintain water balance and improves comfort when skin feels dehydrated or stressed.
Prebiotic Hydration Complex
The combination of Fructooligosaccharides and Beta Vulgaris (Beet) Root Extract forms part of the serum's prebiotic and hydration-support system.
It helps support moisture levels, barrier function and a balanced skin environment.
Glyceryl Glucoside
A powerful moisture-supporting ingredient associated with YOUTH LAB.'s “resurrection plant” hydration technology.
It helps support skin exposed to dehydration stress while improving elasticity, hydration and overall skin comfort.
Sodium PCA
A component associated with the skin's Natural Moisturising Factors. Sodium PCA acts as a humectant to attract and retain water within the outer skin layers.
Aloe Vera
Aloe Barbadensis Leaf Juice provides additional soothing and hydrating support.
Glycerin & Erythritol
Complementary humectants that help attract water and reinforce the formula's multi-pathway hydration system.
