The BRISKIN guide

About BRISKIN

BRISKIN is a Korean skincare brand run by Briskin Co., Ltd., based in Seongsu-dong, Seoul. Its signature line is “my second skin”, and the brand describes itself as a place where nature and science coexist: a special-care brand that aims to offer good cosmetics at a reasonable price.

What are plant exosomes?

Exosomes are tiny vesicles. BRISKIN uses exosomes from plants, and describes them as nano-sized particles that carry nourishing ingredients to the skin. The brand calls its Selaginella exosome ingredient Exopeptide™. Other products use exosomes from Houttuynia cordata (a Korean herb) or oat.

The Selaginella Exopeptide line

Selaginella is the “resurrection plant”: according to the brand, it can survive even in the desert. It is the star of the Exopeptide line. The Selaginella Exopeptide Toner preps the skin, and the Selaginella Exopeptide Skin Booster Cream contains 150,000 ppm of Selaginella exosome, according to the brand, for long-lasting moisture and smooth-feeling skin.

The Selaginella Exopeptide Collagen Mask (single sheet or 5 sheets) is a sheet that, according to the brand, slowly turns transparent as the essence soaks into the skin.

Houttuynia, sun care and base

The Houttuynia Cordata Exo-Barrier line pairs a Skinbooster Serum and a Skinbooster Cream built around the Korean herb Houttuynia. The Real Water Booster Sun Cream is a chemical-filter sunscreen with 65% water essence and 10 types of hyaluronic acid, according to the brand. For makeup, the Exo-Glow Secondskin Cushion gives a dewy finish and, according to the brand, contains a triple exosome from centella, green tea and Houttuynia.

Cleansing, masks and tools

The Exo-Oat Poreless Cleansing Oil contains oat exosome, a plant exosome, according to the brand, and is made to wash out makeup and buildup in pores. The Real Fit Secondskin Mask is a bio-cellulose sheet that the brand presents as one of its best sellers, made to cling to the face like a second skin. For a cool moment after sun or a long day, there is also the Face & Body Calming Ice Therapy tool.

How to build a BRISKIN routine

Morning: a gentle cleanser, the Selaginella Exopeptide Toner, the Skin Booster Cream or the Exo-Barrier Serum, then the Real Water Booster Sun Cream.
