    I would recommend!
    This is a good hydrating serum to add to your night routine, I’ve noticed a big change in my skin after using this serum every night before I go to bed. Pro tip, make sure you’re pairing this with a moisturizer for best results. I normally put this serum on first and then add my moisturizer on top of it. This serum is also good for adding moisture in your skin before you apply makeup for a better look. Overall, I would recommend this to anyone who’s looking for something easy and effective.

    Worth it
    I came across the Korean numbuzin skin care a couple years ago and fell in love with their products. From my own personal experience, their products (including this deep sleep mask serum) has left my skin feeling refreshed, clean, hydrated, and smooth. Their products are very lightweight and doesn’t make your skin feel heavy or sticky at all.

    So lovely!
    I bought this because I noticed it includes algae pretty high up in the ingredients list, which works great for my skin as a hydrator and I always find it leaves my complexion brighter and more even. This does just that, and is also an excellent hydrator. A few drops keeps my face nice and hydrated, and a full dropper will leave you with dewy glass skin. Its also very moisturizing too, and in the summer you could get by with just using this in the morning as a kind of moisturizer. It’s light weight, but I find it leaves a film of moisture all day long (probably from the algae, which has that film forming affect). Highly recommend this to people who are suffering from dry or normal skin or someone who wants to simplify their routine. I don’t think someone with oily skin would like this, because like I said it is pretty moisturizing.

    It could be better… cause what?
    Honestly, I’m very upset that I fell for this particular product. I heard so many claims about the hydration that it gives you, how nice it feels on your skin, however, it almost feels like a serum type of mask when you use it at night. I am trying to use up this whole bottle and I can just tell it’s not giving half of what it claims to. I will say it is very “moist” and doesn’t have a scent but the type of moisture that it gives you is really just that it stays on your face and hardly permeates in. In fact, I would say I feel drier afterwards, but I’ve use other serums that are 10 times better. Deep sleep? I feel like that is mostly just said because of how thick it is. But sometimes if it is too thick, it doesn’t penetrate your skin well. As a dry skin girly, I am missing the hydration for it to truly absorb into my skin. I have to use a serum before this can actually get the moisture in there, but using this alone did absolutely nothing for me. In fact, I felt like the only thing saving my skin was my moisturizer. So of course I switched to a different moisturizer just to test it out and as expected, not only did that moisturizer just sit on my skin along with the product, but I didn’t feel rejuvenated nor was my skin was soft and plump like it usually was. Come morning time and literally felt like I was missing something or hardly did my routine at all. I won’t be buying this product again.

    This is a hidden gem from Numbuzim regarding hydration and anti-aging.It leaves the skin very dewy, plumped and hydrated.I serves both as a serum, as a last step of the skincare routine after the moisturiser in the Pm routine as a deep overnight facial mask and as a primer before makeup.The results are stunning.

    Bene. Pelle secca, ma con zona T, NON è una maschera, ve lo potete usare come siero sotto la protezione SPF, liquidello, che subito uno dice, ma….è acqua? No, ragazzi, mettere sul palmo e spalmare in 3 nanosec, la pelle se lo “beve”.Fantastico in periodo invernale, formulazione da paura (lo usano anche i maschietti di casa: chè, pensavate non ce ne fossimo accorte?Soprattutto tu, caro che ormai hai abbandonato il dopobarba per questo). Consiglio: mettetevelo in carrello, da bravi clienti Prime, che Amazon ogni tanto gli abbassa talmente il prezzo, non pagate le spedizioni e ve lo consegna talmente rapidamente, che altri siti, normalmente più “sponsorizzati” da influencers o quel che l’è mai, perdono competitività in tutto. Sciaquatina alla faccia, siero e SPF, totale, 5minuti. Se poi ve ne scappa 1 filo di troppo, fatelo prima di lavare i denti, così finchè vi lavate i denti, la pelle finisce di “berselo” e via di corsa. Ah, ovviamente, bye-bye brufoli!

    It makes my skin feel moisturized and soft, like I just used a pack. It’s so convenient, so I use it often.
