Piz Buin IN SUN lotion feels amazing, it is thick, but it does not leave a white residue, and it is not greasy either. It has a pleasant smell, not the usual sunblock smell. Unfortunately, this product is only SPF15, which is not good enough for the South African summer sun. The higher SPF Piz Buin lotions would definitely be on my summer must-have list. This range of products is COLIPA compliant, which means that they are on the CANSA recommended list. I wouldn’t buy or recommend this SPF15 product, however anything SPF30 or over in this range would be amazing. SPF15 may be good enough for people who aren’t exposed to direct sunlight, and are mainly indoors or maybe in winter. I am very strict with sunblock all year round, so for me at least an SPF30 is a must.
