I have a love-hate relationship with anti-aging products. Love sầu them because I’m getting khổng lồ that age where my skin needs them, hate them because brands seem to think anti-aging = rich và heavy *rolls eyes*.

So when I learned about the Klairs Midnight Blue Youth Activating Drop, I kept my fingers crossed that this was the one.

bFGF – Basic fibroblast growth factors can help accelerate wound healing và prevent soto formations3.Blueberry fruit extract – contains resveratrol, which is an excellent antioxidant.

What impresses me most about the Midnight Blue Youth Activating drops is the high concentration of the anti-aging ingredients: 93% of the total weight is the EGG + bFGF. For me I’d rather have just a few potent ingredients rather than a bunch of ingredients at low concentrations.

Growth factors – just a hype or the real deal?

EFG & bFGF sound like the ikhuyến mãi anti-aging ingredient on paper – it works to repair and regenerate our skin5, stimulate collagen production6, & replace damaged (whether by environmental factors or UV rays) cells with healthy ones7.

They actually occur naturally in our bodies và thus don’t cause the same irritation as other anti-aging ingredients like retinol và vitamin c. But as with all good things, EGF levels rapidly decrease in our mid-20’s, and your skin is no longer able to repair itself as quickly as before. Cue in the loss of elastithành phố and appearance of fine lines.

While growth factors sound wonderful, their molecule sizes are generally also too large to lớn be absorbed by the skin, though micro-needling or the use of a penetration enhancer lượt thích butylene glycol (included in the Klairs Midnight Blue Youth Activating Drop) can help8.

Lastly, EGFs’ effects on the skin are nowhere near as well studied as retinol or other better known anti-aging ingredients, though current research shows promising results.

So no, growth factors aren’t perfect, but from what we know so far, they’re living up lớn the hype. I wouldn’t toss out your retinol just yet, but growth factors are a great anti-aging ingredient khổng lồ consider especially if you want something gentle và effective.

How lớn use the Klairs Midnight Blue Youth Activating Drops

According lớn my esthetician, EGF products should be the first thing applied after cleansing & exfoliating. This is to ensure the ingredients are properly absorbed inkhổng lồ your skin.EGF should also be used twice a day khổng lồ get the best results.Due lớn the watery texture, I would either add the drops to lớn your palm & then pat it in, or drop it directly on your skin making sure the pipette doesn’t touch anything!I use 3-4 drops for my face.

Usage experience & results


First thing I love about the Klairs Midnight Blue Youth Activating Drops? How lightweight it is. If you struggle with layering products because they start lớn feel heavy, this serum is the perfect addition lớn your routine.

It’s literally lượt thích applying water, which can actually be tricky at times because it’s too watery. This is the one time where I vì suggest dropping the product directly on your face – just make sure the pipette doesn’t touch your skin!

Next, products containing growth factors can be expensive – lượt thích $100+ expensive sầu. I’m really impressed that Klairs was able khổng lồ deliver EGFs in such high concentration at a reasonable price, but none of this matters unless the sản phẩm works, which brings us to…

Does the Klairs Midnight Blue Youth Activating Drop work?

This is always a tough question, especially for anti-aging products. Klairs cleverly markets this as a hàng hóa that “delays aging”, not one that reverses the signs of aging, which really is what 99% of all anti-aging products are. Luckily I don’t have sầu any wrinkles yet, so for me using the Youth Activating Drop is definitely about prevention.

It’s like applying water khổng lồ your skin

It took finishing an entire bottle to lớn realize that my skin feels smoother, more refined, and generally healthier. The changes are subtle, và it might even take you stopping the product completely for a while khổng lồ realize the difference it made!

As with all anti-aging products, it takes continuous long term use lớn notice the effects (ie. the delay in lines & wrinkles), so I’m more than happy with the general improvements I’ve sầu already seen.

What others are saying

Full Reviews are linked so if your skin type matches, I highly recommend reading further lớn get a better idea of how this sản phẩm will work for your skin type!

I don’t think this serum alone can transkhung my skin in a spectacular way. On the other hvà, I think it’s one of these products that are perfectas an allyfor the stronger treatments that I love sầu, such as retinol và acids.

Bonnie of BTY ALY, dehydrated combination skin

After one week of using the Klairs Midnight Blue Youth Activating Drop, my skin texture has improved. In fact, I feel like it’s smoother now and brighter so I guess the skin repair does really work.

Alyssa of Style Vanity, oily acne-prone skin

As said, it is hard lớn say how effective sầu peptides act when applied topically, even when they are applied as first sản phẩm after cleansing.Somehow, the serum still has a good effect on the skin & makes it feel soft. I don’t think that it will reduce any existing wrinkles though.

Laven of Berries in the Snow, dry skin

It’s hard for me to lớn say about wrinkles because it’s not really my problem and I feel lượt thích wrinkles need more time to see the results but I totally see the difference with pores & my skin in general – it seems lớn be more healthy, glowy và pores seems lớn be cleaner.

Klairs Midnight Blue Youth Activating Drop alternatives

When I started testing out this sản phẩm at the end of June, I was immediately reminded of theHylamide SubQ Anti-Age Serumbecause they’re so similar in function, kích cỡ, và texture. So to lớn make things easier, here’s a comparison table:

Klairs Midnight Blue Youth Activating DropHylamide SubQ Anti-Age Serum
$30/25ml ($1.2/ml)$38/30ml ($1.27/ml)
Features EGF & bFGF as the main anti-aging ingredientsContains 6 different anti-aging ingredients, no growth factors thought
Also contains soothing & calming ingredientsAlso contains hydrating ingredients
10 ingredients total (full list)36 ingredients (full list)
Doesn’t irritate sensitive sầu or inflamed skinCan sting when used on already irritated skin
No scentSmells lượt thích wet rags
Water-like texture, no sticky finishWater-like texture, just a hint of stickiness that fades quickly

As much as I love the idea of having a smorgasbord of anti-aging ingredient in one hàng hóa, my skin just reacts better to simple ingredient listsbecauseit means less chances of ingredient conflict, allergy reaction, or potential irritation.

Even when my skin is sensitive sầu I’m able khổng lồ use the Youth Activating Drop without any issues, whereas the Hylamide serum stung & irritated my skin further.

Other EGF serums I’ve tried

Skinmedica TNS+ Advanced Serum – For $265 this did deliver more noticeable results than the Klairs. Is it worth the drastic price difference? If you’re under 30, heông chồng no, please save sầu your money & use the Midnight Blue Youth Activating Drops instead. If you’re older & have the budget, Skinmedica’s formula is undeniably better.

PCA SKIN Total Strength Serum – At $98, this is middle ground between the Skinmedica & Klairs, và uses both EGF và peptides for its anti-aging functions. Sadly I did not notice results with this one :(
