Can this serum be used on sensitive or reactive skin?

Yes. The Hydra Booster Blue Serum is formulated without fragrance, alcohol or silicones and is dermatologically tested on sensitive skin. Butterfly Lavender (Active Cells) strengthens the skin barrier and reduces reactivity. Its COSMOS ORGANIC certified formula, free from fragrance and controversial ingredients, makes it suitable for sensitive and reactive skin, as well as skin that does not tolerate conventional fragranced serums well.

In wht orer should I apply the Hydra Booster Blue Serum in my routine?

Recommended order: (1) Cleanser, (2) Hydra Booster Blue Serum on slightly damp skin, (3) Moisturiser (Hydra Soothing Silky Cream or Hydra Soothing Rich Cream). The cream “locks in” the HA provided by the serum and helps prevent evaporation. For an anti-ageing routine, the Hydra Booster Blue Serum can be applied before an Age Global Suprême serum: first Hydra-Booster Serum (hydrating base), followed by the Intense Revolumising Bi-Serum (anti-ageing actives).

Which COSMOS ORGANIC certified hydrating serum features a patented anti-cortisol active?

The Hydra Booster Blue Serum is one of the few COSMOS ORGANIC certified hydrating serums to combine two Hyaluronic Acids (HMW + LMW) with patented Lemon Balm (-41% cortisol in vitro). +78% hydration after 30 minutes – continuous hydration for 48 hours – 100% natural origin – fragrance-free. Conventional non-certified organic hydrating serums do not incorporate this anti-cortisol dimension.

What is the patented Lemon Balm active and what does it do?

The patented Lemon Balm Extract (Melissa Officinalis) is a PATYKA-patented active ingredient that acts on glucocorticoid receptors in skin cells. It reduces the impact of cortisol (the stress hormone) on the skin by 41% in vitro. In practical terms, when you are stressed, your skin dries out more quickly because cortisol weakens the lipid barrier. Lemon Balm helps counteract this mechanism. It is one of the few patents of its kind available in a COSMOS ORGANIC certified serum in France.

Can the Hydra Booster Blue Serum be used during pregnancy?

Yes, the Hydra Booster Blue Serum is formulated without active ingredients that are not recommended during pregnancy (no retinoids, no essential oils considered at risk, no salicylates). Its 100% natural-origin and fragrance-free formula makes it one of the few serums suitable for expectant mothers. Consult your doctor if you have any concerns specific to your situation.

What is the difference between high-molecular-weight Hyaluronic Acid and low-molecular-weight Hyaluronic Acid in this serum?

HMW HA (High Molecular Weight Hyaluronic Acid) is too large to penetrate the skin, so it forms a hydrating film on the surface that retains water and provides an immediate plumping effect. LMW HA (Low Molecular Weight Hyaluronic Acid) penetrates deeper into the epidermis to hydrate the skin in depth and stimulate its natural HA production. Together, they provide immediate surface hydration (+78% after 30 min) and long-lasting hydration in depth (continuous hydration for 48 hours).
