Smells amazing. Lightweight non greasy
Style: SPF 70, Size: 6.5 Ounce (Pack of 1)
Smells amazing. Lightly citrusy sweet, but not too much. Just barely enough to cover the sunscreen smell. Very lightweight and not greasy.

Perfect for Brown Skin – No White Cast!
Style: SPF 70, Size: 6.5 Ounce (Pack of 1)
This sunscreen spray is absolutely perfect for my kids with brown skin! It goes on clear and dries quickly with no white cast at all — which is a huge win since so many sunscreens leave a chalky residue on deeper skin tones.
It’s super easy to apply (especially on wiggly kids), and the SPF 70 gives great protection during long days at the pool or beach. It’s lightweight, non-greasy, and water-resistant too.
Highly recommend for parents looking for strong sun protection that actually works on melanin-rich skin without that ashy look!
