    Probably not

    It's too watery and difficult to apply. I don't see much benefit on my skin, and if it weren't so runny, at least it would be easier to use.

    Perfect for me after treatment

    I get a skin treatment every 3 months, and I use this serum 4-5 days after the treatment when my redness, skin peeling, and sensitivity go away. It's very watery and light; my skin just absorbs it immediately. It works for me, but anyone who gets a skin treatment should consult with their skincare specialist.

    Great serum, absorbs quickly

    Very light serum, absorbs very quickly into my skin. Seems to reduce appearance of fine lines on my Asian skin. Love this product.

    Good serum

    Good but not great… I haven’t found yet (my) HG for peptides and I’ll keep looking but this is not it. I bought it twice as I wasn’t sure the first time since the bottle is so small (the skin just drinks it up I can’t even spread it fast enough I needed 2 full pumps to feel I’ve applied on my entire face and neck). There was a slight improvement in the skin texture but easy to overlook. For this price I’m sure K beauty has better options.

    Glowing and healthy skin

    I've been using this serum for a week. I haven't seen any difference in my wrinkles so far, but it is too soon to tell. However, I can say that my skin looks very healthy and hydrated and it is partly thanks to this serum. I use it at night after toning and before my retinol so that my skin is soothed and supple, prepared for my cream with retinol. These blue drops are helping my skin to combat dryness and peeling which can be caused by retinol. Liking them.

    I really wanted to like it but...

    I didn't. It feels like coloured water. I once tried the Midnight blue cream and thought it was amazing. The drop doesn't come even close to the cream. It's not irritating but I also don't see any positive effects.

    Love it! Serum that actually gives results!

    Total fan! It's lightly scented & very soothing for my skin. After a couple days of using my skin looks so much better! Too bad that the bottle is so small -would gladly bathe in it XD

    Glowing serum

    Watery serum that makes my skin glow!! I haven't really noticed any difference in my small wrinkles but definitely it has improved my skin appearance.

    Staple in my routine

    My sensitive skin can handle this quite well. I started using it to deal with redness and skin cell turnover. Can't say much about the latter but didn't notice anything „bad“ happening either. It's probably my 5th bottle now, will repurchase again

    Moisturizing and restoring aid

    Effective but not very spectacular - it will help your stressed and dry skin to relax and restore but the anti-aging effect is not really visible.

    here's my somewhat scientific outlook on this

    i was surprised that the bottle was so small and there wasn't even a full ounce of product but i guess that's my fault for not reading the details thoroughly. the liquid is blue and has no scent. i bought this because i was attracted to the clean ingredient list but my skin doesn't feel special after application. i'll continue to use it occasionally because it COULD have little microscopic benefits (hopefully). i don't really know the science behind applying EGF and FGF topically on your skin. i'm speculating that they won't do much since the top layer of your skin is composed of protective dead skin cells layered on top of each other. skincare products usually can't penetrate through to the inner layers so i wouldn't think that EGF can even take effect. there's also not a lot of scientific evidence that these types of amino acids can reduce the appearance of wrinkles. these peptides are usually involved in wound healing, and wrinkles aren't wounds.

    Meh

    It's a ok serum. Nothing amazing. It's quick absorbed by my skin, which is a plus but there isn't any visible effects.

    I have been using this serum for a month now. It is very light and not sticky, and also no irritation on my sensitive oily skin.
