Technical specifications
A lightweight serum with hyaluronic acid and glycerin that gives your skin an instant hydration boost and improves skin comfort every day.
Hydrating Serum
This Hydrating Serum has been formulated to provide the skin with instant hydration while leaving a light, fresh and comfortable finish.
Its formula combines hyaluronic acid, vegetable glycerin and pentylene glycol to deeply moisturise, help hold water in the upper layers of the skin and support the skin barrier.

The brand presents hyaluronic acid as an active that forms a moisture-retaining layer on the skin’s surface, helping to keep it instantly hydrated and better protected against water loss. Glycerin attracts and holds water, while pentylene glycol also acts as a moisturiser and contributes to the overall effectiveness of the formula.
Its lightweight texture suits all skin types, including sensitive skin. The formula is 0% fragrance, hypoallergenic and non-comedogenic. The official product page also states that it can be used safely during pregnancy.
The serum can be used morning and evening as part of a daily routine, before your cream, to boost the skin’s hydration and improve its feeling of suppleness and comfort. The brand also indicates that it can be used on its own after sun exposure or on the neck for extra hydration.
How does this serum work?
Hyaluronic acid helps the skin retain water and enhances the feeling of instant hydration. It also contributes to skin comfort by limiting dehydration.
Vegetable glycerin acts as a humectant, drawing water into the upper layers of the skin, which helps keep it soft, supple and comfortable throughout the day.
Pentylene glycol complements this action by providing additional moisturising support, while contributing to the stability and effectiveness of the formula.
