Can I use my sun protection products from last year, this year? Will they be less effective?

If you store your sun protection products properly, it is possible to use last year’s products. Their protection factor will be basically the same. Make sure to wipe the opening of your sunscreen immediately after use, then return the cap properly before storing it in a location out of direct sunlight with a constant temperature. However, avoid use if you notice a strange odour or that the product has separated, as this means the product quality is compromised. As much as possible, we recommend using up new products within that season.
