    here's my somewhat scientific outlook on this
    December 30, 2018
    (i gave this 5 stars just to get this review near the top)
    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.

    Brightened and smooth skin

    I have been using the Midnight Blue Youth Activator for about a year now. My skin looks healthy and tightened. I am 56 years old, overall my skin looks and feels smooth and calm. Highly recommend this product.

    Best antiageing serum!
    July 17, 2018
    From my experience the only skincare that helped me diminish finlines and wrinkles wich I have around my eyes and nazolabial area are the EGF skincare products. They don't just plump the skin temporary like most of the antiageing skincare does,  they really do some permanent results. Current favourite is the klairs midnight blue youth activating drop. Packed with different type of EGF molecules and blueberry extract and guaiazulene= skin repair and calming. This serum removed my fine lines and wrinkles. I've used many bottles already and will continue using it.

    Have noticed a big difference straight away.
    November 3, 2018
    Very good product and very gentle. I have incredibly sensitive skin and this doesn’t irritate it at all. Product left my skin feeling smoother and helped with redness and my dark circles too!

    magic in a bottle
    January 31, 2019
    best anti aging serum there is! im on my 4th bottle. best when paired with snail essence and vit c/e serums.
    Works like magic
    September 5, 2017
    I dont know what sorcery this is, but whatever it is in this tiny bottle is nothing but pure magic. I dont normally wear makeup and if i do, it's very minimal, usually just to even out my skin tone. When i started using this, i no longer have to wear any makeup at all! Nada. Nothing. It evened out my skintone in less than a week. Purchasing another one as my stock is nearing empty. I dont see this product leaving my kit anytime soon. One of my wisest buys.

    A Must Buy
    November 20, 2017
    This stuff works like magic. It has completely transformed my skin. My pores have shrunk, skin-tone has improved with lesser uneven and patchy skin. I recommend this to everyone.

    Amazing for healing the skin
    June 24, 2020
    I am personally 20 years old so I don't really have any troubles yes with aging. I wanted to use this more as an preventive serum. I have combination acne prone skin with slight rosacea. This serum helps a lot in calming and healing my skin. I can immediately notice a difference in the morning when I ise this at night. It's calms my skin down and it has helped smooth my skin texture a lot. It's just an overall great serum that I would also recommend for younger people. One tip is to immediately drop the product on your skin and pat it in. When I used it for the first time I put some in my hands first, but by the time I wanted to apply it to my face it had absorbed into my hands. Do make sure the tip of the dropper doesn't touch your skin though. You don't want to put bacteria back in the bottle. The only downside to this porudct is that there isn't much in here. So i do wish they'll make the bottle bigger.

    This comes highly recommended by Gothamista so it must good! I use it every night and have already repurchased twice. It really helps my skin recover after my Tretinoin treatment. Try it!

    Good product!
    August 16, 2017
    I haven't used this serum for too long but I've already noticed that my skin seems smoother, less inflamed and it calms down any redness, so thank you :-) you do only need a small amount and I hope the longer I use it, the more improvement I'll see.
  • Cheryll

    Lessen my fine lines perfect with midnight blue calming cream. I ❤️ Klairs products best for sensitive skin.
  • LaRue
    Great product
    November 7, 2018
    Absorbs into the skin immediately and leaves it feeling hydrated and soothed. After a while of use I feel like this has lessened the appearance of fine lines and improved skin firmness. I use this together with the Midnight Blue Calming Cream and it's a perfect duo.
