A serum aimed at the look of redness on reactive skin
Thalgo Cica Marin Soothing Anti-Redness Serum is a soothing serum for sensitive skin with visible redness, the first step of Thalgo's Cica Marin SOS range. It concentrates the marine prebiotic Halymenia Durvillei extract and a patented micronised algae filtrate to calm discomfort and support the skin's own defences, in a serum designed to be layered under the range's cream or fluid.
The texture
A fluid, fast-absorbing serum with a cooling feel on contact.
Who it suits
- Sensitive skin with visible redness or flushing
- Skin that feels hot, tight or uncomfortable
- Anyone starting a soothing routine for reactive skin
- Use before the Soothing Cream or Soothing Fluid
Worth knowing before you buy: the formula contains fragrance. It targets the look of redness; it does not treat a diagnosed skin condition.
