Thick, doesn't blend
Size: 1.76 Ounce (Pack of 1)
I hated this. It claims to have no white cast but thats just becuase the tinted color sits on top of your skin and gives a really caked on look. It is impossible to rub in and just feels like cheap sunscreen. It was very expensive for the small tube. I wouldn't recommend this at all.

Me encanto. Excelente producto.. Lo recomiendo al 100%.
La única observación que podría hacerle es que se ve un muy blanco para mí color de piel, peor lo difumino bien y listo.
