Formula IngredientHumectantHyaluronic Acid
INCI: Hyaluronic Acid
Hyaluronic acid (HA) is a naturally occurring polysaccharide found throughout the human body, particularly in skin, joints, and connective tissue. It acts as a powerful water-binding agent, capable of holding up to 1000 times its own weight in water. High-molecular-weight forms sit on the skin surface to hydrate and support barrier function, while lower-molecular-weight variants penetrate slightly deeper into the epidermis.

Is Hyaluronic Acid safe? Key considerations
Can Hyaluronic Acid cause irritation?
Low RiskGenerally very well tolerated by all skin types. Ultra-low-molecular-weight HA (under 50 kDa) may have mild pro-inflammatory activity at high concentrations in disrupted skin barriers; standard consumer products use higher molecular weights that are non-irritating. Not restricted under EU cosmetic regulations (no Annex II/III listing).
Does Hyaluronic Acid increase sun sensitivity?
No RiskHyaluronic acid does not increase photosensitivity. No SPF precautions required specifically for HA use.
Is Hyaluronic Acid safe during pregnancy?
SafeHyaluronic acid is a naturally occurring substance in the human body. Topical application is considered safe during pregnancy. No known risks identified; widely regarded as pregnancy-safe by dermatologists.

Hyaluronic acid (HA) is a naturally occurring polysaccharide found throughout the human body, particularly in skin, joints, and connective tissue.

Individuals with known allergy to hyaluronic acid or sodium hyaluronate (very rare) should review the considerations above before use.
