Perfect sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
I love the roll on sunscreen. It is quicker to apply and my little one can help without squeezing sunscreen everywhere. Will buy again.

Protection with days of white residue
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Mineral sunscreens have yet to master blending in and this is no different. If you're thinking of hitting the beach with your sexy bum protected it'd better be a ghost beach because you'll look like you've been dipped in white paint. Oh, and it doesn't wash off, so be prepared to look like Casper for days to come.
It rolls on fine if you shake it well first and it does protect.

Neutrogena clear face loción de protección para el sol
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Neutrogena Clear Face Sun Protection Lotion is one of the most popular options for the face, especially if you have oily or acne-prone skin.
General opinion: it is a very good sunscreen for daily use, light and designed not to cause outbreaks.
The positive:
* It is oil-free and non-comedogenic, that is, it does not usually cover pores
* It has a light texture and "matte" type, it does not leave the skin greasy
* Absorbs quickly and can be used under makeup
* Offers good SPF 50 protection against UVA/UVB rays
* Many people with acne skin say that it does not cause pimples
The not so good:
* On very oily skin it can be a little shiny over the hours
* It is not super moisturizing (if you have dry skin, it may feel a little "light")
* Some people may be slightly irritated if they have very sensitive skin
Final opinion:
It is a highly recommended sunscreen if you have combination or oily skin and want something that does not cause acne. It is practical, cheap and reliable for day to day, but it is not the most "perfect" if you are looking for a totally dry finish or super hydration.
If you want, tell me your skin type (dry, oily or mixed) and I'll tell you if it's the best option for you or if there's an even better one.
