Regardless of SPF level — whether SPF 30, 50, or 100 — all sunscreens should be reapplied every 2 hours when you are outdoors. Higher SPF does not extend the reapplication window; it only increases the percentage of UV rays blocked. La Roche-Posay themselves recommend this on all product labels.
La Roche-Posay sunscreen products get recommendations from skin doctors and use special technology called Cell-Ox Shield. It ties antioxidants with defense against UVA and UVB rays. In the Anthelios series, this unique system protects the skin against free radicals.
The company blends deep knowledge about skin care with filters for sunscreen that protects against both kinds of UV rays.
La Roche-Posay Sunscreens for All Skin Types
The tinted Anthelios sunscreen for face is made up of 100% mineral ingredients. It offers broad spectrum protection with SPF 50 and works for all skin types including sensitive. Broad spectrum means that it defends against UVA and UVB rays.
The brand stresses face sunscreen that combines top defense against sun with extra benefits for the skin.
Between the most popular products are the Anthelios Melt-In Milk sunscreen with SPF 60, available for face and body. There is also the Anthelios UV Right SPF 70 Everyday Lotion. Those sunscreen products are designed to last through water and sweat, so they work well for sports and physical movement.
The range UVMune 400 drew much interest because of a new ingredient from the brand. The FDA approved Mexoryl 400 as a filter for very long UV rays in the range of 380 to 400 nanometers. The invisible liquid UVMune 400 has a light, non-greasy feel that blends easily with the skin.
It does not go in the eyes or cause stinging, and its smell is much moor gentle than that of other chemical based sunscreen products. The UVMune Oil Control Gel Cream with SPF 50 offers a bit less bright option, although some users mention that it can pill on the skin.
There is also a fresh sunscreen serum loaded with antioxidants. It feels invisible on the skin and has a texture that one describes as light as air. The brand puts its own prebiotic thermal spring water in its products.
The ultra-shiny liquid sunscreen works well for oily skin. The Double Repair UV with SPF 30 is another option that sits nicely on the skin without too heavy or too shiny feeling. The Anthelios Dry Touch gives a light, non-greasy feel, although some find it hard to apply on the face.
One good choice applies to wet skin and is strongly resistant against water. It feels comfortable, not too sticky or greasy, and does not leave white filmy leftovers.
L’Oréal controls La Roche-Posay together with CeraVe. Some skin doctors suggest the brand over others, like Cetaphil Suntivity 50+ for skin prone to breakouts. Both versions, tinted andcolourless, rate very alike according to quality.
