How to use
Kiehl's DS RTN Renewing Serum: After toning with toner once a day, apply 2-3 pumps to the entire face, followed by cream or emulsion. Recommended for use at night. Avoid use on the upper eyelids and lips, where the skin is particularly thin. Avoid contact with eyes. Use one pump on the neck and décolleté. Always apply sunscreen when using in the morning. Kiehl's Cream UFC: After cleansing your face morning and evening, and toning with toner or serum, apply a pearl-sized amount (approximately 8mm) to the entire face. Apply additional layers to dry areas for enhanced moisture. Kiehl's DS Clearly Bright Essence : After cleansing your face and toning with toner, take one dropper (about the size of a 100 yen coin) and gently smooth over the entire face. Gently apply additional layers to areas of concern, pressing with your hands. Use Kiehl's DS Pre-Serum every morning and evening. After cleansing and wiping your face, take one dropper and gently apply it to your entire face. Then, condition your skin with lotion, serum, and cream. If using during the day, be sure to apply sunscreen.

I love this product! My skin feels so smooth the next day, and I haven't had any reaction to it, so it's really easy to use. I've repurchased it several times.
I bought 30ml, but the volume was surprisingly small and it was gone quickly. There was no particular scent and the texture was a thick cream, but it spread well, I guess? However, I didn't feel much effect. It's also expensive, so I don't think I'll buy it again.
I was worried about the irritation of retinol serums, but I was surprised at how easy this was to use. Since I started using it, my skin texture has improved, and it feels so much smoother when I touch it after washing my face in the morning. My skin has also gradually become firmer, and it looks healthier. Rather than having an immediate effect, I feel like my skin's overall condition improves with continued use. I think this serum is recommended even for those new to retinol.
I've been hearing a lot about ethynol and have been curious about it, but I wondered what it was and wondered if my current skincare routine was enough. When I asked Chappy about it, he told me that adding ethynol would be even better for me, and out of several types he suggested, I bought this one. As I'm a beginner, he said to use it only at night 2-3 times a week. If I see any changes, I'll consult Chappy again and consider the frequency and type of use! I'm looking forward to it lol
