Achieve professional-level skincare effects at home! Chemical peeling you can do at home. This product is a high-quality home chemical peel. High concentration: TCA 100% Trichloroacetic acid Capacity: 1 dram (3 ml) Brand new, completely unopened. This is recommended for those who want to try a small amount. Beauty clinics charge around 5,000 to 15,000 yen per session, but with this product, you can do it several times, making it very economical. I have personally tried various peels such as pumpkin peel, salicylic acid peel, and glycolic acid peel. Among them, TCA (Trichloroacetic acid) was the most effective and caused the least damage to the skin. It was exceptionally high-performing compared to others. Since using TCA, I haven't looked at other peels and have only used TCA, and my face and body have become unbelievably beautiful. I didn't see much change even after spending a lot of money on treatments at medical institutions, but one bottle of TCA had a greater effect. Now, I believe that using different concentrations of TCA is the best way to achieve beautiful skin. Instructions are not included, so please purchase this product if you know how to use it or have experience using high-concentration peeling solutions. Only one bottle of the product will be sent. Shipping is free. I also have other TCA products with different price ranges, concentrations, and capacities. Thank you.
