Talk to your doctor always before using a new product on your baby's skin before 6 months! I love this sunscreen! I gives me such peace of mind when bringing my little ones out in the sun over the summer. It is super thick, so a little goes a long way! It covers any area completely, takes a bit to rub in, but doesn't leave a greasy feeling. Best part? It won't drip when your little one is sweating, so no sunscreen burning their eyes!

Good

Size: 3 Fl Oz (Pack of 1)

Whole family continues to purchase/use this sunscreen even though my child is no longer a baby. It does leave some white residue/cast. I haven't found a mineral sunscreen that doesn't.

No horrible white haze

Size: 3 Fl Oz (Pack of 1)

This is the first all zinc sunscreen I have used that has not turned my skin, a pasty white. However, it has dried my skin out so now I am mixing it with oil and rubbing it in. I know it's diluting the sunscreen in it, but at least it's natural and my skin is not dry.

The best!

This lotion will change your life. It smells SO good and leaves your skin incredibly soft. Super hydrating. It is great for after tanning. It will rehydrate your skin after that. I don’t know if it really locks in the color, or if that is just a high quality tan bed that I use. Either way- It’s a gem!
