Centella Sunscreen Use: Apply and Reapply Sun Serum UV

The SKIN1004 Hyalu-Cica Water-Fit Sun Serum UV is the centella sunscreen sold on the US store at USD 17.10 for a 50ml tube, and its use comes down to three moves: apply it as the last step of skincare, apply it liberally 15 minutes before sun exposure, and reapply at least every 2 hours. Hyalu-Cica Water-Fit Sun Serum UV dries to a fresh finish with no white cast. Hyalu-Cica Water-Fit Sun Serum UV suits combination and dry skin.

The US tube is easy to tell apart by the UV at the end of its name and by its four active ingredients: Avobenzone 2.7%, Homosalate 13.6%, Octisalate 4.5% and Octocrylene 9%. Behind the filters sit Panthenol, Centella Asiatica Extract and three forms of hyaluronic acid, which is why it spreads like a watery serum. It comes as a single 50ml tube or a Twin Pack of two 50ml tubes.

Apply it as the last step of skincare

The Hyalu-Cica Water-Fit Sun Serum UV goes on after cleansing, after an ampoule or serum, and after moisturizer if your skin needs one. Sunscreen sits on top of the routine so that nothing applied later thins the layer. Dispense the sun serum into your palm.

Apply it evenly over every area the sun will reach: face, neck, arms and legs. On the face, spread it from the center outward and go back over the sides of the nose, the hairline, the jaw and the tops of the ears, the spots most often missed. Apply it liberally and evenly, and finish the neck in the same pass.

Then wait 15 minutes before going out into the sun. If you wear foundation, press it on with a sponge or brush once the sunscreen has absorbed, and keep the base thin so the sunscreen layer stays intact underneath.

Reapply at least every 2 hours

One morning layer does not last the day. Reapply the Hyalu-Cica Water-Fit Sun Serum UV at least every 2 hours. That interval applies to every area you covered in the morning, the arms and neck included.

On bare skin, reapply the same way as the first layer: a liberal amount, spread evenly, edges and ears included. Over makeup, blot oil first with a tissue, then press the serum over the face with your fingertips, a pat at a time, until the whole face is covered evenly with a liberal amount. A 50ml tube in a bag or desk drawer makes the 2 hour interval easy to keep; the Twin Pack covers a home tube and a travel tube.

Pair it with the other sun protection steps

Sunscreen is one part of sun protection. Alongside regular use of the Hyalu-Cica Water-Fit Sun Serum UV, limit time in the sun, especially from 10 a.m. to 2 p.m. and wear long sleeves, pants, hats and sunglasses. Used as directed with those measures, broad spectrum sunscreen decreases the risk of skin cancer and early skin aging caused by the sun.

Keep it out of the eyes and rinse with water if it gets in, apply it to intact skin, stop use and ask a doctor if a rash occurs, and ask a doctor before use on children under 6 months of age.

The full ingredient list and both sizes are on the Hyalu-Cica Water-Fit Sun Serum UV product page, next to the morning routine it closes for SKIN1004 skincare.
