3. Texture & Smell

Like any other serum, the Klairs Blue Drop is very watery. It’s very hard to apply the drops straight to your face as it just runs down, so I would highly recommend to put some drops on your hands first and gently pat it onto your face. There is no sticky or oily feeling to the product. The serum penetrates the skin instantly, which makes it very easy for layering products.

There is no noticeable scent, just a faint typical skincare product scent.

The colour of the serum is blue, as blueberry extract is one of the ingredients.

6. Personal Review

I have been including serums into my might skincare routine for a very long time. Before using this Klairs youth activating drop, I was using the Wishtrend vitamin C serum. With serums you never really see any obvious improvements of your skin but I’m sure my skin tone improved since I have been using this Klairs serum.

It’s very easy to apply and as it’s water based, it doesn’t feel sticky or oily. My skin is generally quite dry, so I really need to put essence, serum and moisturizer on my face twice a day.

The skin under my eyes is always a bit puffy or dark, I do notice that this serum makes the skin under my eyes look less dull. Usually Korean people always ask if I’m sick or tired, but since I have been using this serum I haven’t had anyone ask me this yet.

I haven’t had any negative reaction, which I haven’t had with any Klairs products. My skin is really sensitive and I easily get allergic skin reactions to skincare or cosmetic products.

How To Use Klairs Midnight Blue Youth Activating Drop

This serum is meant to be used in the evening. First use a cleanser to clean your face and right after use the Klairs drop. This should be applied before using a toner. Apply at least 3 or 4 drops and use your hands to gently pat the serum on your face.
