A detoxifying serum for skin that looks worn down by city life
Thalgo Spiruline Boost Detoxifying Serum is a detoxifying serum from Thalgo's Spiruline Boost range, designed for skin that looks tired and congested from daily pollution exposure. It concentrates spirulina with marine magnesium and hyaluronic acid, to help energise the complexion and support the skin's natural defences, in a serum meant to be layered under the range's cream or gel-cream.
The texture
A fluid, fast-absorbing serum that leaves no residue and layers easily under a moisturiser.
Who it suits
- Tired, congested-looking skin
- City dwellers wanting an extra layer of daily protection
- Anyone building a full Spiruline Boost routine
- A morning step before the moisturiser
Worth knowing before you buy: the formula contains fragrance. It is an energising, protective serum, not a medical detox treatment.
