CLAIM TO FAME: Klairs’ first anti-aging product that works to repair the damage of time on skin

FAST FACTS: Age-combating night serum; reduces visible wrinkles; brightens skin tone; helps delay skin’s aging process by replenishing collagen and natural elasticity; infused with a high concentration of EGF (20 ppm) and bFGF (10 ppm); formulated with only 10 ingredients, which don’t include water; calms skin that’s been irritated by UV rays with guaiazulene

PERFECT FOR: Youthful, healthy, glowing skin

”I’ve been enjoying this nightly for about two weeks now and absolutely in love with it. It’s a very lightweight watery type of serum. It’s more so in line with first essence toners when it comes to it’s usability and benefits but with potency of serum! I’ve been using it right after thorough cleansing and light watery toner, and then follow up this Klairs serum with my regular skin care routine. I didn’t notice much benefits for the first few days other than the fact that it wasn’t irritating my super sensitive skin. And after about 10 days of nightly use, I noticed that my skin looks healthier and smoother. I haven’t changed anything else in my nightly skin care routine so I’m convinced that it’s this little serum that I have to thank for. My skin looks overall revitalized and healthier since I started this serum. I haven’t notice direct improvement on fine lines just yet but I do feel that my skin is smoother and see a definite potential of further skin improvement with this serum.”

This one really is a game changer! I have been looking for a beauty product which will address my ageing problems being in the forties and all, and this one just made my search done with! I feel that my skin tightened days after using it! I use it day and night and although its says not to use with other products, I combine it with Dear Klair's toner, and in some days when I feel like having a dewy-smooth finish I use Banilla's Ms. Flower and Mr. Honey cream with it. So yes, I do very much highly recommend this to women my age.

Great alternative for pregnant

I use this product in place of my Ordinary Retinol since I got pregnant as part of my night time skincare routine. I use this first, then the Thayers toner then Niacinamide and lastly moisturizer. This would replace the benefit I get from retinol which is to prevent skin aging. I learned that this combined with niacinamide would produce more collagen on my skin.

One of the best serum! Promise!

Dear Klairs is my new love! I usually don't buy them since they're pricey! But when I shifted my skincare to Dear Klairs products, I was really surprised how effective they are. I start with my routine with the Rich Foaming Wash, then Supple Toner, then Midnight Blue Youth Drop, then Vitamin C and lastly is the Calming Cream At night. I use the Vitamin E in the morning. :) This is the best routine I ever had! Love love! I love the effect of this serum, this is one of the best anti-aging product that I used ever! It reduces visible wrinkles and brightens my skin tone. A must buy!

A skin care fave!

As a young adult, I try to upgrade my skin care. This product alongside the vitamin C serum is indeed a great combination! After using this for a few weeks, my family immediately saw results and said my skin looks better. It is also lightweight and feels just like water, you just have to tap it into the skin. It doesn’t have a smell so that’s a plus! I loved it so much I’m already on my second bottle.

Its my favorite EGF peptide treatment I have learned from gothamista! I have been using it for years, since ecq, Im really glad that I can comfortably order it here. Its unique blue drop effectively soothes and rejuvinates my skin before I put my moisturizer, Im using it day and night. It something worth keeping in my routine.🤍
