Should I use sun protection with this serum?

Sun protection should always be adapted to your skin type, phototype, the daily UV index, your level of exposure and your lifestyle.
However, in summer, regardless of skin type, the use of a high sun protection is essential and should be reapplied every two hours in case of prolonged exposure.

Here are a few practical examples and our recommendations:
It's summer, and Clementine, who has dark skin prone to spots, walks 20 minutes to work every day. For her, applying a high sun protection every morning is essential, and reapplication is absolutely necessary if she goes out for lunch.
Marie plays sport or works outdoors all year round. For her, regardless of the season, the use of an SPF50 is essential and must be reapplied every two hours due to prolonged exposure.
Emma, who has fair skin, takes public transport to work and stays indoors all day. Her outdoor breaks are short because it is winter and the weather is often cloudy. In her case, sun protection is not necessary; an antioxidant moisturising cream is sufficient to help protect the skin from free radicals.
