1. Which pore tightening agent works? 2. If using Witch Hazel to tighten pores, how many %, and how long will it take to see results?

I personally use L-ascorbic acid see the best results. There are other personal items that do not irritate the skin. Fullerene , Phytosphingosine SA that has been used has been good. Which depends on the skin of each person as well. As for Witch Hazel The rate of use like a Toner is 50% or more, but the results in pore tightening. Only when using will not produce the same results as the substances suggested above. If used together would be great.

Thank you for recommending. In case of tightening pores 1. If using l ascorbic acid how much do you use? 2.If you use Fullerene how much do you use? 3.If you use Phytosphingosine SA how much do you use?

Use it under the recommended rate. 1. Recommend no more than 15% or use a small % rate first. It can irritate your skin. Try using Vitamin CE Ferulic or Stabilized Vitamin C Serum of the company first 2.Recommend 0.2% 3.Not more than 0.2%

Thank you very much from experience. Fullerene How long does it take to see the change?

I'm not sure because it's used with other substances as well. There may be some bias towards the outcome of Fullerene but if any formula used contains ingredients Fullerene , the pores appear smaller. smoother face compared to other formulas that do not have Fullerene or other formulas that do not contain pore-tightening ingredients, according to research I've read, 8 weeks is recommended. go up

thank you
