科颜氏 DS RTN 焕肤精华液，50毫升

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 usually use DHC retinol, but the sample of Kiehl's was good so I bought the full product for the first time. I have a problem with my pores so I use Kiehl's Vitamin C serum, but I would like to use this serum at night. My skin became smooth when I used the sample, so I'm looking forward to seeing how my skin will be when I finish using it.

Effective for firmness and radiance. I used up three bottles in search of firmness and radiance. I think it was effective because I was able to put it in my beautiful skin. The capacity is large, so I was able to use it for several months. However, since the bottle is glass, I wondered if I could use it until the very end. It's expensive, so I wanted to use it even if I had to dig it out. After that, I wanted an effect on my pores, so I tried another retinol, but it was more effective on my pores, so I switched to that one.

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 a trial size! I was a little hesitant to try it, but it works for my skin! I'm going to keep using it!
