desertcart.com: DearKlairs EGF Serum - Blue Youth Activating Drop, 0.67 Fl Oz | Barrier Repair & Post-Blemish Marks, Sensitive Skin-Friendly, Daily Calm & Soothe, Korean EGF serum : Beauty & Personal Care

Review: Really helped with my back acne marks - Pros: I am a huge fan of dearKlairs products and this EGF Serum has honestly become one of my favorite steps in my routine. I dealing with acne so anything that targets post blemish marks catches my attention, and this serum has done a great job helping fade some of the marks left behind after breakouts. The texture is water light and absorbs within seconds, leaving absolutely no stickiness or residue behind, which makes it so easy to layer under the rest of my products. I have combination skin with an oily t zone and this serum has been great for oil moisture barrier support since it helps keep my skin balanced without adding any extra weight or oiliness. I also appreciate that DearKlairs uses this at the front of the routine right after cleansing, since it really does seem to prep my skin and help everything else I put on afterward absorb better. The blue color comes from Guaiazulene and it genuinely does seem to visibly calm any redness or irritation I have going on, especially since I naturally deal with redness on my cheeks and around my nose. I did not notice any fragrance at all which I always appreciate given how reactive my skin can be. A few drops go a long way and it never feels like it is sitting on top of my skin, it truly sinks in and gets to work. Cons: The dropper style bottle means I have to be a little more careful and intentional with dispensing since it is easy to use more product than I actually need if I am not paying attention. I also think the post blemish mark improvement has been more gradual for me rather than an overnight change, so this is definitely a product that requires consistent daily use to really see the benefits over time.
Review: 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.

## Questions & Answers

**Q: So this should be applied before toner as well? So it should go cleanse, blue drop, klairs preparation toner, klairs rich moist soothing serum, etc???**
A: Hi,
I agree with your proposed regime.  Apply the midnight blue youth activating drop immediately after your double cleanse, then follow up with some hydrating toners and essences, then any other serum and moisturizer of choice.
I have found Klairs midnight blue youth activating drops to be very effective.  It has been 'out of stock ' on the Amazon site for some time now.
Regards

**Q: Is it cruelty free?**
A: Sure, all products of Klairs are cruelty free.

**Q: Can you use this on the same night you use a retenoid product? If so, should it be before or after? Thanks**
A: Yes you can because that what I did but I have very sensitive skin so I had to use the retinoid with it every other day for like two weeks so my skin got used to it then I was able to use it every night. I would use 5 drops of this product and pat it all over my face(do not rub) and then I would put my retinoid product on top of it. You’ll really love this product.

**Q: Is this meant only for night?**
A: I use it morning and night when I feel like it. There is no reason why you can't use it in the day if you feel you need extra help from the peptides.  It is quite a small bottle though, so I tend to use it only at night.  It plays well with all my actives and serums, I tend to cocktail it rather then layer.
