You asked, we delivered. Out #1 bestselling serum is here in new size 60ml – and now you can bag the double size duo too. Double the size, double the serum, double the hydrated, firmer, and plumper skin.

​Formulated with 2% multi-molecular Hyaluronic Acid, this powerful moisture-binding ingredient can hold up to 1000x its weight in water, which is essential for maintaining skin hydration and plumpness.

Helping to combat dry skin, improve the appearance of fine lines and helps maintain an effective skin barrier, it’s a must-have for every skincare routine.

Reviews Summary
Customers say this serum absorbs quickly into the skin and provides immediate hydration. Many reviews mention its lightweight, non-sticky texture that layers well with other products. The serum leaves skin feeling plump and soft, with users particularly appreciating its gentle formula. While most find it deeply hydrating, a few note it's basic in performance. Frequent comments address its versatility in skincare routines and easy application. Some mention the packaging could be improved for better dispensing.
