What is it: Take a deep dive into refreshing hydration with the Blue Marine Algae Intense Hydrating Treatment Mask from Peter Thomas Roth. It helps smooth skin, leaving it feeling soft and instantly hydrated with a dewy, radiant glow.

Who is it for: All skin types, especially those looking for deep hydration.

Why is it different: Glacial lake Blue Marine Algae contains nutrients, antioxidant-rich tea, Antarcticine, sourced from glacial ice, and other ingredients that help provide the skin with hydration.

How do I use it: Apply a generous coat on clean skin. Allow mask to remain on for 10 minutes. Rinse with cool water. For an intensive treatment, apply a thin layer as the last layer of skin care and leave on overnight. Use two to three times a week or daily for deep nourishment. For a very cool and refreshing treatment, refrigerate product and then apply.

Rated 2 out of 5 by from Not for sensitive skin It's such a shame that PTR uses such good, innovative natural ingredients then ruins and cheapens their products with chemicals like phenoxyethanol. My face turned red on contact. The rose stem cell product line is the only one of theirs I can use. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Awesome I love PTR and use all of his masks. This is one I had not tried yet. I love it. It's a gel that is very springy. Not watery at all. You use barely any. I put it on last at bedtime and wear it all night. My face is better than ever in the mornings! I never could get used to putting on thick heavy night cream. I am 56 with combo skin, sagging but not wrinkled. This seems to plump me up and smooth/soften my face and neck. I highly recommend it.

Rated 5 out of 5 by from Truly one of a kind!! I was so impressed with this mask. I applied it and it felt like nothing on my skin. It had none of the usual mask problems i.e. overwhelming smell. Super uncomfortable. What a pleasant surprise. Now I see why these masks of PTR are literally famous. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Hydration station Iif Aquaman (hot new justice league Jason Momoa aquaman, not 90s cartoon) emerged from the ocean and gently caressed your cheek while telling you how beautiful you are, that's how this mask makes my skin feel. There's so much hydration my skin isn't even sure what to do with itself so it just glows with radiance. So, short version, just buy the mask, now.
