A weekly mask that tops up hydration in one sitting
Thalgo Source Marine Rehydrating Pro Mask is a rinse-off cream mask for dehydrated skin, meant as a weekly boost alongside the Source Marine daily routine. It delivers a concentrated dose of sève bleue des océans, alginates and micronised algae filtrate in ten minutes, so skin looks plumper and feels more comfortable straight after rinsing.
The texture
A rich, creamy mask that spreads easily and rinses off cleanly with warm water.
Who it suits
- Dehydrated skin before a special occasion
- A weekly top-up alongside daily Source Marine care
- Skin that looks dull or feels rough to the touch
- All skin types affected by dehydration
Worth knowing before you buy: the formula contains fragrance. Leave-on time matters: rinse off after about ten minutes rather than longer.
