Me sorprendió la protección, mi hija no se quemó ni un poco
Size: 3 Fl Oz (Pack of 1), Size: 3 Fl Oz (Pack of 1)
Tengo una bebe de 3 meses, íbamos para la playa por primera vez (vivimos en el caribe) necesitaba un protector solar que me permitiera protegerla del sol directo, pero sin químicos y que fuera gentil con su piel. Ya había utilizado el jabón de la marca y me pareció excelente idea comprar el protector por lo que ofrece. No me arrepiento, la textura al inicio me pareció densa, pero luego cuando lo esparcí bien en todo el cuerpo de mi bebé me gustó, no deja la piel blanquecina, se incorpora bien en la piel, no tiene olor fuerte y puedo decir que para mi asombro la niña no se quemó ni un poquito, es decir me sorprendió que teniendo una tez tan blanca no se quedara ni roja. Este protector solar superó literalmente mis expectativas.

Babies products so please fix this product and sell again.
Size: 3 Fl Oz (Pack of 1)
Very disappointed with this sunscreen. The product came out watery and separated like oil and liquid mixed together. Even after shaking, the texture felt weird and uneven. It leaves a heavy white cast, feels greasy, and doesn’t blend well into the skin. Definitely not the quality I expected, and I don’t feel confident using it for proper sun protection. Would not buy again.

safe and peace of mind!
Size: 3 Fl Oz (Pack of 1)
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.
