KLAIRS Midnight Blue Youth Activating Drop – What Happened Later Review

(Not sponsored. No affiliate links.)

What is it?

„The KLAIRS Midnight Blue Youth Activating Drop does exactly what it’s named after. It is a night serum used before going to bed that has a blue tint due to guaiazulene in the formula. Made with EGF (sh-Oligopeptide-1), bFGF (sh-Polypeptide-1), and 95% raw materials for anti-aging effects, the EGF and bFGF activate the key factors in the skin to help improve the overall health and quality of the skin. Although the packaging may be small, it’s only made with 10 core ingredients without the use of purified water as a high concentration high strength delay-aging serum.“

Klairs, Korean skin care brand under Wishtrend’s umbrella launched this anti-age serum in the summer of 2017. It’s been super hyped and super popular in the skin care community. Reviewed so many times, praised so highly. However, was it really that efficient and what it did to skin after prolonged use? I am reviewing this serum now, after several months of use and one emptied bottle of it to answer these questions.

Klairs Midnight Blue Youth Activating Drop comes in little 20 ml / 0.67 fl.oz. dark glass bottle with the pipette. Intensive blue colour comes from Guaiazulene, dark blue crystalline hydrocarbon derived from chamomile oil.

It is very watery and has faint yeasty scent. When opened, should be used within six months.

How to use it?

“Before going to bed, and after cleansing, use the applicator to apply 3-4 drops of the blue drop to the face and quickly absorb into the skin.

It’s best you use this blue drop at the first step of your skincare routine.

Please take care in following application order, as applying an oily product beforehand can interfere with the blue drop’s absorption.”

Ok, I did it exactly how Klairs recommended. No toner before, just the first step after cleansing and always in pm routines.

However, you can use this serum after toner if you apply your toner with cotton pad (think something like Etude House SoonJung pH 5.5 Relief Toner) and that toner isn’t essence or gel type.

If you apply your toners with your hands, then Klairs Midnight Blue Activating Youth Drop should be applied first.

You can also use it as eye serum. Just apply it around eyes, then drench the thin (you don’t want to lose 30$ serum to cotton) pad with this serum and leave it under eyes for couple of minutes for brightening effect. Especially if you have dark circles under eyes. This should help. I personally didn’t use it this way as dark circles under eyes are not one (more) of my skin’s battles, but I heard people swore it had worked for them.

No need to wait before applying other skin care steps. It’s fit for everyday use and doesn’t collide with other actives.


sh-Oligopeptide-1, sh-Polypeptide-1, Butylene Glycol, Vaccinium Angustifolium (Blueberry) Fruit Extract, Sorbitan Sesquioleate, PEG-60 Hydrogenated Castor Oil, Chlorphenesin, Guaiazulene, Ethylhexylglycerin, Adenosine

No water. Only ten ingredients. Highly concentrated.

sh-Oligopeptide-1 or Epidermal Growth Factor (EGF) is protein responsible for stimulating collagen production and it’s vital in skin healing processes. It is also impossible not to mention Italian developmental biologist Rita Levi-Montalcini and the American biochemist Stanley Cohen as their discovery of nerve growth factor (NGF) and epidermal growth factor (EGF) won Nobel Prize in 1986 in Physiology or Medicine (more on: https://www.nobelprize.org/nobel_prizes/medicine/laureates/1986/press.html).

sh-Polypeptide-1 or Basic Fibroblast Growth Factor (bFGF) stimulates cell proliferation, collagen production and skin renewal.

Blueberry fruit extract has astringent and moisturizing properties. Rich with antioxidants.

Guaiazulene besides the intensive blue colour has also the anti-inflammatory properties.

Adenosine is yeast-derived beneficial antiaging and skin soothing ingredient.

Rosacea safe?


Who is it for?

All skin types


Did it work? How did it actually perform?

Here I am now, a half year later, with one empty bottle of Klairs Midnight Blue Youth Activating Drop contemplating of repurchasing it. Or not.

It did soothe my skin after cleansing. And that was the most obvious effect of this serum. All red and flushed after cleansing would immediately go into its normal not red/not flushed state.

My skin is aging and needs all the help it can get to remain where it’s now, to say the least. I can see some improvement with my overall skin texture, but these changes are so subtle that it’s really hard to tell whether something good happened. Or maybe I should buy a better magnifying glass. Yet, nothing bad happened either. No irritations, no skin flushing, no bumps, no pimples.

But I can’t say that this serum did nothing. Because it did. After (quite) some time that normal, not red/not flushed skin rendered the usual sight.

Those wrinkles that were here before still are. Pores are a bit tightened.

Ok, to conclude. This serum is not something that could be used all alone for one to expect some dramatic results over it. No, that will not happen. That cosmetic panacea, unfortunately, is not exactly up for grabs (yet). But, this serum is actually an excellent side kick to all the actives, essences, serums and other lotions and potions that were created to make us more beautiful.

You promise a younger skin last longer? I know you are sweet talking me, Klairs, but I’ll take it.
