MAN...... MA SKIN LOVES THIS PRODUCT
[Dear Klairs] Midnight Blue Youth Activating Drop is a skincare product that has gained popularity for its claims of providing anti-aging benefits and improving overall skin health. After using this product for several weeks, I can confidently say that it lives up to many of its promises. First and foremost, one of the standout features of this product is its beautiful packaging. The deep blue glass bottle not only looks luxurious but also helps protect the product from light and air, ensuring its stability and efficacy. The dropper dispenser makes it easy to control the amount of product you use, preventing wastage. In terms of the product's performance, the Midnight Blue Youth Activating Drop contains key ingredients like EGF (Epidermal Growth Factor) and Blueberry Extract, both of which are known for their potential in improving skin elasticity and reducing the signs of aging. EGF is believed to stimulate skin cell renewal, leading to smoother, more youthful-looking skin. Over the weeks of consistent use, I noticed a visible improvement in the texture and firmness of my skin. Fine lines appeared less pronounced, and my skin felt noticeably smoother and more supple. One of the aspects I appreciate most about this product is its lightweight and non-greasy texture. It absorbs quickly into the skin, leaving no residue behind. This makes it suitable for both morning and evening use, and it can easily be incorporated into your existing skincare routine. While the Midnight Blue Youth Activating Drop delivers promising results, it's worth noting that individual experiences may vary. Additionally, it's important to use this product consistently and give it time to work its magic, as anti-aging effects may not be immediately visible. In conclusion, [Dear Klairs] Midnight Blue Youth Activating Drop is a highly effective serum that lives up to its claims of promoting skin youthfulness and vitality. Its elegant packaging, fast-absorbing formula, and noticeable results make it a valuable addition to any anti-aging skincare routine. While it may be a bit on the expensive side, the quality and performance justify the price for those seeking to improve their skin's overall health and appearance.

Really Works
At first I wasn’t expecting all that much from this. When I bought it I thought at best it would sooth some of my skin sensitivity and maybe reduce redness based on other reviews but it is way better than I expected. It is pretty much the consistency of water which is a little off putting at first but I find it a absorbs into my skin very quickly and it feels very silky when I’m rubbing it in. It’s not hydrating on its own but I use it as the first thing I put on my face after cleansing (then toner, essence, etc.). Since I started using this about a month ago I’ve noticed that my skin feels less irritated and my acne heals more quickly and the scars are less dark. This isn’t an acne solution, I don’t think it’s significantly changed how many pimples I get, but that’s not what it’s advertised to do. It does however speed up healing and make scarring less severe. It does seem to calm my skin and make it less red and over heated. I’ve also noticed a significant reduction in the few fine lines I have. I’m only 23 so wrinkles are not at the top of my skincare priorities but I had started to get some lines on my forehead and after trying a few different creams and seeing no improvement I had given up since my skin is too sensitive to use stronger/harsher anti-aging products but, to my surprise, after a little less than a month of using this I noticed the fine lines on my forehead are much less visible and are smoother. Overall I feel like this has improved my skin and made it less irritated and healthier. My only complaint is the packaging. Since it is a very thin, watery consistency it can be hard to stop it from dripping off your face before you put the dropper back in the bottle and rub it in. This has led to some frantic fumbling with the tiny bottle first thing in the morning. In fact the reason I’m here is to buy another bottle because I knocked mine over and nearly all of it spilled out since there’s not much to begin with. A tragedy. I’ve had the bottle for one month and I suspect it would have lasted another month or two if I hadn’t spilled it. I wish the bottle came with a spray nozzle instead of a dropper as that makes more sense for something of this consistency, in my opinion. If they must stick with the dropper then making the bottle heavier bottomed and a little squatter at least would help. I have several other products that come in dropper bottles and none are so precarious as this one. But clearly the product itself is worth the trouble or I wouldn’t be buying a new one.

Works for sensitive skin!
I was looking for a peptide product for a beginner with sensitive, dry, rosacea skin - this is great! Makes my skin glow and it’s lightweight. Recommend!

If you have hypersensitive skin, this is a God send!
Been needing a little extra something to add to my skincare routine. I have hypersensitive skin (CeraVe, Cetaphil and a few Korean products irritate my skin) and it's always a gamble when I try a product suitable for sensitive skin. I used it at night as directed and was ready to wake up with red bumpy skin. To my biggest surprise and relief, my skin barrier significantly improved and I had a beautiful glow! By the third day, my skin was radiant and my stubborn dry areas were no longer flaky! I purchased the smallest size, but I will be purchasing the largest size when I run out!

Great for Combination Skin, Noticeable Improvement!
I have combination skin, and after consistently using the blue serum, I’ve noticed an overall improvement in my skin condition. It absorbs quickly without leaving any stickiness, making it perfect for layering in my nighttime routine. The peptides help with skin elasticity, and the guaiazulene provides a soothing effect, especially after a long day. Over time, my skin looks smoother, healthier, and more balanced. The only downside is the small bottle size. I really wish a 50ml version was available on Amazon! This serum works so well that I find myself repurchasing often. I highly recommend it to anyone with combination skin looking for a lightweight, anti-aging serum!

I thought I was getting more product..my bad.
This is watery and drips everywhere if you aren't careful, I think it should've come w a pump or spray instead so we can just pump directly on to skin. I've found holding the dropper horizontally helps me control the release of the serum much better. The bottle is tiny, only 20 mls, and easy to tip over. This isn't cheap and I've noticed Korean skin care is going up up up in prices and I'm not sure many products are a great value anymore nor more effective than other brands. There are some formulations that I love and will continue to recommend and purchase, but as a whole category, I'm not sure about all the hype. I'm being harsh, I know, bc there's nothing really wrong w this product other than the price and the delivery system. I just wish there was more in this bottle in terms of ingredients and volume. For example, Sephora's Drunk Elephant Protein has 9 peptides, of which there are 2 in this product. It's also 2 and a half times more product, plus more antioxidants, amino acids and the vehicle delivery is much easier to use. If you don't want to pay Drunk Elephant prices, Acure Whipped Night cream is another option w the same 9 peptides at only $21. As I try to narrow down my regiment and clear the clutter, the most effective parts of my routine are actually French brands and tret. The best vitamin C products have been American/Canadian. Anything extra that I use is kind of extra fluff. This one is fluff.

Skin barrier repair that actually works
Finally a bigger size!! This has been my go-to daily serum because it actually works without being heavy, but the small bottle always ran out too fast. So glad they finally released a larger version, and the new packaging looks even better!

Makes my blemishes lighter
It leaves a special feeling of moisture and coating on the skin. I use it every night. When I wake up, my skin looks hydrated. It makes it easier to apply make-up. After a month of using it, the blemishes (from acne) on my skin are lighter. I'll continue using it and see if my blemishes will fully disappear.

Parfait 👍🏻
Ce produit skincare m'a été recommandé dans ma routine Kbeauty pour le matin et soir. Et honnêtement, je suis bluffée. Ma peau est très sensible et là aucune réactivité, douce hydratée sans être collante et le lendemain matin, elle reste fraîche et douce. Je recommanderais sans hésiter
