Neova Ti-SILC is a sunblock that has been recommended to me for post-peels or after extended retinol treatment. Since it is so gentle and effective, it is a great option for anyone who wants a good sunscreen without fear of allergic reactions. Neova Ti-SILC comes in SP45 and SP60 (the latter is supposed to be effective even after 80 minutes in water). The Neova range is based on GHK copper peptides, which makes this sunscreen round effective anti-aging solution.
