科颜氏视黄醇精华入门套装，50毫升

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
