I have actually used a few things they tend to recommend in Korea. This is what got me looking into surgery over there.
So the first product is simple and cheap, a jade roller! You can look into the benefits of it. You can buy them on Amazon.
The second product is Rejuran Healer Turnover Ampoule. It contains polynucleotides that come from salmon and it helps the skin regenerate faster as well as encourages collagen production.
