Phloretin CF

I found that this product did not stand out for me. I tested it for about 2 weeks and I didn't see any difference. I also didn't find it to have a pleasant smell. This costs a considerable price in the store and I don't think it's worth it at all. Thanks @ [~weareeves] for letting me test this product! #weareeves #skinceuticals

I got to test this serum, and overall, I'm really happy with it! But I'm wondering something. Because it contains spf 50. But you only have to use 5 drops for your entire face and neck. Can this then provide sufficient protection against the sun. Since you really have to apply a good amount of sunscreen to get actual protection. Is there anyone who can tell me this?
