Sea Cycle: High Tide Serum

ConceptsBeauty & Personal Care

A lightweight hydrating serum with seaweed-derived texture, anti-pollution actives and DNA protection.

At high tide, the ocean brings minerals and nutrients to the shoreline. High Tide Serum reflects this replenishing movement, reviving skin with a burst of hydration.
The lightweight gel combines a texture derived from sustainably sourced seaweed with anti-pollution and DNA-protecting actives to strengthen the skin’s natural defences, leaving it refreshed and ready for the day ahead.

Formulation Expertise:

Beauté by Roquette AG291 needs to be carefully added to water with fast stirring to avoid clumping. Alternatively, it can be premixed with a humectant, e.g. glycerin or PO500 until smooth and then added to the water. Mix for minimum 40 minutes to ensure full hydration before any further ingredients are added.
