Details
Heyday Serum (30ml) is the brand's dedicated deep-hydration treatment, built around a standout 1.125% Panthenol concentration one of the highest in a daily serum format to deliver lasting moisture, barrier repair, and a visible plumping effect on dry or dehydrated skin. Panthenol (Provitamin B5) converts to Pantothenic Acid within the skin, actively supporting tissue repair, reducing surface roughness, and retaining moisture so the skin feels genuinely softer and more resilient rather than just temporarily hydrated. A three-molecular-weight Hyaluronic Acid complex full-size Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, and Sodium Hyaluronate layers hydration at multiple depths simultaneously for a plumped, dewy finish that lasts throughout the day. Adenosine adds targeted anti-ageing support, helping to soften the look of fine lines and improve elasticity with continued use. A rich botanical base of over 15 plant extracts, including Cotton Fruit Water and Mallow Extract, provides additional soothing and conditioning benefits. Fragrance-free, vegan, cruelty-free, and tested for sensitive skin, this serum is ideal for dry, dehydrated, or barrier-compromised skin needing deep, lasting replenishment.
