What is in Madagascar Centella Hyalu-Cica Water-Fit Sun Serum?
SKIN1004’s Hyalu-Cica Water-Fit Sun Serum is a chemical sunscreen in a serum texture, labelled SPF50+ PA++++. The filters named on UK retailer listings — Uvinul A Plus, ethylhexyl triazone, Tinosorb M and diethylhexyl butamido triazone — are modern filters permitted in the UK and EU but not in US sunscreens. Around them sit Madagascar centella asiatica extract, hyaluronic acid and niacinamide.
The brand and retailers describe a light, dewy finish with no white cast. Those are manufacturer descriptions of texture; The Cast Index has not tested SPF, UVA protection or wear.
03 / Review
Who is Madagascar Centella Hyalu-Cica Water-Fit Sun Serum best for?
Readers who find cream sunscreens heavy under makeup and want a protect step that behaves more like a serum. The dewy finish suits normal to dry skin, or sits well under a matte base; very oily skin may want to set the centre of the face.

What should you check before buying?
Check the name: the international Water-Fit Sun Serum and the US Sun Serum UV share branding but not filters. There is no UK brand shop — the global store prices in US dollars and the buyer pays import charges — so authorised UK retailers are the simpler route. No water resistance is claimed; reapply after swimming, sweating or towelling.
05 / How to use it
How should you use Madagascar Centella Hyalu-Cica Water-Fit Sun Serum?
- 01Apply as the last step of morning skincare, before makeup
- 02Use enough to cover face, neck and ears evenly — a thin layer gives less protection than the label states
- 03Reapply at least every two hours outdoors, and after swimming, sweating or towelling
- 04Remove at night with your usual cleanser
