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. ## Frequently Bought Together - DearKlairs Midnight Blue Youth Activating Drop, 0.67 fl oz (20 ml) | Breakout Care & Sebum Control, Dual EGF, Peptides, Guaiazulene, Adenosine, Lightweight, Oily Skin - DearKlairs Midnight Blue Calming Cream, Soothing, Redness Relief Moisturizer, Hydrating, Fast Absorbing, Light Texture for Easy Use, For Oily Skin, Sensitive Skin Friendly (2 Ounce (Pack of 1)) - DearKlairs Freshly Juiced Vitamin Drop, 5% Hypoallergenic pure vitamin C serum, 1.18oz | Ascorbic acid, antioxidant for face, korean skincare --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/45216226-egf-serum-blue-youth-activating-drop-0-67-fl-oz](https://www.desertcart.sk/products/45216226-egf-serum-blue-youth-activating-drop-0-67-fl-oz) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-23*
