## Features

- [TARGET POST-BLEMISH MARKS WITH EGF PEPTIDE] Formulated at 10ppm — the maximum concentration permitted in Korea — to support skin's natural cell renewal cycle. In a consumer study, post-blemish marks appeared visibly improved by 14.75% in two weeks and 23.21% in four weeks of daily use.
- [EGF & FGF FOR FINE LINES AND SENSITIVE SKIN] EGF and FGF growth factors support skin's natural recovery — helping improve the look of fine lines and texture for sensitive skin not ready for harsh anti-aging actives.
- [LIGHTWEIGHT SERUM DESIGNED FOR SENSITIVE SKIN] The water-light drop texture absorbs in seconds with no stickiness and no residue — comfortable and non-disruptive for morning or evening use.
- [CLINICALLY TESTED AND NON-COMEDOGENIC] Dermatologist-tested to visibly reduce the look of irritation by 46.53% in three minutes; proven non-comedogenic and suitable for acne-prone, oily, combination, and reactive skin types.
- [NATURAL BLUE CALMING COMPLEX] 1,000ppm Guaiazulene melts into skin to visibly soothe redness and irritation — the source of the serum's signature blue color, free from artificial coloring and artificial fragrance.
- [HOW TO USE] As the first step after cleansing, dispense 3–4 drops onto bare skin and pat gently to absorb — before toner, moisturizer, and any other actives.

## 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.
