  • "I absolutely love this moisturizer!  It is so lightweight and it has SPF 50 in it, which is amazing! I always want to make sure I am protecting my skin as well as taking care of it by moisturizing it.  This product does not have a "sunscreen" smell to it either, so it is perfect for everyday use!  It goes really well under makeup as well.  It doesn't all up or anything under makeup.  Great product!!" in 7 reviews

This sunscreen is absolute perfection. It is SO lightweight. I layer it on top of a serum and my moisturizer and then put makeup on top. Feels like I'm not wearing any sunscreen. The bottle is somewhat small, so when I purchased it I was worried I would run out. But a single bottle has lasted me 3 months and still hasn't run out. Reasonably priced, will absolutely buy again.

This is my ride or die, holy grail facial sunscreen. I use this every single day under my primer and foundation, or by itself over my regular skincare. I have very oily, acne prone skin, and this product is a godsend. It has a high level of zinc oxide, which is great for clearing up blemishes and protecting from the sun. It goes on kinda white but blends in quickly. It doesn't leave a film on my skin like some sunscreens do. I have used several foundations and primers over this and it plays nicely with them all. My only advice is to do a thorough cleanse at night, because this and other physical sunscreens are harder to wash off. Yoh don't want this to build up in your pores and cause blemishes. An excellent sunscreen for every day.

I got this sunscreen/moisturizer in a suncare kit from sephora. I hadn’t had much experience with algenist before, but I was really impressed. The texture is kind of mousse-like, so it goes on really light and fluffy- very impressive considering it’s spf 50!

Absolutely obsessed with the entire line!!!! I wish the price wasn't so high... but it's so very worth it. I typically order this through Dermstor.com....and I've found it on Amazon as well. The brand is amazing...I've tried a good bit of their products and they all have met or exceeded my expectations. This product included. I'm about to be 31 with an extremely stressful job in an ICU as a nurse...I work 13 hour shifts, get very little sleep, could use some better overall nutrition and in the summer I'm a beach bum sun worshiper...and engine who sees me even with no makeup on would swear to you I couldn't possibly be a day past my mid 20's.

This is the perfect sunscreen for the person that hates wearing sunscreen.

It’s super lightweight, doesn’t leave a cast on darker skin tones , and is spf 50. What more could you ask for? The price point is also great in contrast with its competitors.

I have added this to my night time regime, once a week, and I will never look back. It has made my skin so incredibly soft & youthful. It has the lightest most elegant scent & feel on the skin.

I didn’t like this sunscreen as it caused me to get shiny. It was disappointing as I really like Algenist and was looking for a new product for my face. A Sephora rep recommended this product after we talked. It was a bit expensive for a facial sunscreen. I returned the product to Sephora. I’m still looking for another facial sunscreen.

Light enough to mix with my moisturizer. Makeup applies well over it, which is nice. It isn’t greasy or heavy and doesn’t have a strong smell. Not particularly affordable, but a little goes a long way, too.

Love this stuff! I mean the natural occurring collagen sourced from photo-plankton is genius!

Goes on so light and soaks right in! No harsh smells or irritating chemicals!

I noticed a #improvement in #tone #texture #pores #radiance and a reduction of the fine line and wrinkles within my 1st week of using it!

It’s pretty pricey but I cannot live without it!

1 oz seems like an awful small amount. How long does this product usually last for?
