I’m 52 and post-menopausal with mature, dry skin, and this serum has been such a comfort to use. I’ve been dealing with a serious eye infection and had to completely stop using actives, so my skin has needed gentle hydration and calming support more than anything. This has been perfect. The texture is lightweight, soothing, and immediately comfortable on the skin. It absorbs easily without any stickiness or heaviness and gives my skin that hydrated, cushioned feeling without irritation. Even when my skin feels stressed or reactive, this goes on smoothly and feels calming rather than overwhelming. What I really appreciate is how well it hydrates without doing too much. My skin feels balanced and comfortable throughout the day, not tight or dry, and there’s no redness or stinging. It’s been ideal during a time when my routine had to be very minimal and gentle. Despite how simple and calming it is, it still makes my skin look healthier and more refreshed. My complexion looks smoother and more hydrated, even without the help of stronger treatments. It layers well under moisturizer and works equally well morning and night. This is an excellent serum for anyone who needs hydration and soothing without actives, especially during periods of sensitivity or recovery. I’ve really come to rely on it, and it’s something I’ll continue to keep in my routine even once my skin is back to normal.

Personally, this serum is my holy grail skincare product for sensitive, acne-prone skin. I have dry skin with hormonal cystic acne around my jawline, cheeks, and neck, and always broke out with other popular products (SKIN1004 Centella, Beauty of Joseon Glow Serum, COSRX Snail Mucin, Mixoon Bean Serum, etc.). However, after trying this serum, my skin went from flaky and irritated to hydrated and soft! I used 2 pumps morning and night for 3 months, and my acne flareups calmed down significantly. This serum also works well with Tretinoin cream, which is notorious for drying out the skin. I personally did not experience any reaction from this combination, which was unusual but amazing! Here are some answers to common questions as a fellow skincare girly: Scent: None Color: None Texture: Clear gel Lightweight: Yes, very. It's not super glowy or heavy, but still hydrating Absorption: Very good, does not "sit" on your skin at all Bottle Longevity: Around 2 months (using 3-ish pumps per day) Hydration: Yes; good for dry, flaky acne-prone skin Skin Reaction: Personally none--no redness, stinging, etc. When to Use: I like to use it morning and night, but it's up to you! Under Makeup: Great base, doesn't cause pilling or unevenness

I've tried a lot of serums - a lot - and this one has become non-negotiable for me. I genuinely never want to live without it. I originally bought it at Olive Young in South Korea and fell in love with it. The pantothenic acid is incredibly soothing without being heavy. My skin just drinks it up and calms down immediately. I use it when my skin is irritated, when it's not, when I'm trying a new product - basically all the time. I even use it with my red light therapy devise as it's water-based. It layers beautifully with everything else in my routine and never causes issues. No breakouts, no irritation, just smooth, happy skin. The texture is perfect - not too thick, not too watery.

Es muy ligero; sin embargo a mi piel no le cayó muy bien. Soy muy sensible y hago comedones

This was honestly the best serum I ever used It cleared my skin up It was nice going on It didn't cause any breakouts for me 10 out of 10 love it It feels so refreshing going on it's just my favorite serum of all time it's worth the money it's honestly a very good price for a serum though in my opinion works very well absorbs very quick makes my skin so bright

Omg this is literally my Holy Grail in a bottle. if you have constant hormonal acne then this is for you. The serum is so hydrating and moisturizing. It leaves my skin feeling so nice, within the first week I saw results of my acne being less red and less painful. It really helped calm down my acne, and whenever I would get a pimple, it wouldn't be as painful or big. You can use this in the day and the night, but I'd usually use it at night.

I took this picture right after I removed it from the box- it was already missing some product (not as pictured on the listing). I did a patch test first- I think it’ll definitely help control oil throughout the day so I’m excited to try it. It does feel somewhat drying. I’m over 35 and have combo/oily skin, so I’ll be using a very hydrating moisturizer underneath and exfoliating weekly to prevent drying and clogged pores. Hoping this will be a summer staple! **Providing this update after a few uses- it was definitely too drying no matter what my routine was or what moisturizers I used with it. It gave me dry patches on my cheekbones which I’d never had before. I think it’ll work better for younger, oily skin.

I rarely write reviews but I had to for this product. I have tried SO many products to tame my hormonal acne in my 30s and one thing that has really helped is taking Pantothenic Acid vitamins (i take 6 every day) but it wasn't completely stopping the deep cysts that would come during my cycle. I figured if taking the vitamins helped, maybe using Pantothenic B5 topically could only make things better. When I discovered this product I immediately bought it and use it just in the morning after watching my face. I noticed the difference immediately!! I started using this January 1 and it's now Jan 22 as I write this review. So three weeks later and my skin is truly transformed! I haven't gotten any more deep, painful cysts and any acne I do get is very small and goes away within a day and barely leaves a mark now. This is my holy grail product i think. I hope they never discontinue it! My skin LOVES it. So if you've noticed a difference in your skin with taking B5, I definitely recommend trying this serum!

Great product, does what it says, it soothes my skin brilliantly

Me ayudó mucho a controlar el brillo en mi piel , me ayudó con mis manchitas
