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???

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

Sure, all products of Klairs are cruelty free.

Can you use this on the same night you use a retenoid product? If so, should it be before or after? Thanks

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.

Is this meant only for night?

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.
