The BRTC V10 Multi-Lift Sleeping Pack comes in an 80ml or 2.7oz polyplastic tube for $29 as of this writing. Everything on the box is essentially in Korean. No instructions. So I used this the way I use other sleeping packs/masks, at the end of my routine, applying an even layer to my face and neck before bed. I would recommend makers who distribute this in the states to please include English-translated ingredients and instructions. I appreciate all of the marketing speak of "vitamin-rich," "brightening," and "firming or hydration," along with the colorful imagery and packaging. Still, I'd like to know what I'm putting on my face and how to do so. I have managed to glean this sleeping pack, which is essentially a lotion you apply before bed. While it is called a sleeping pack, you could use this day or night, according to the sales post. But be prepared; it is going to leave you tacky and sticky and take a while to melt into the skin. It has Centella Leaf Water (35%), spirulina, broccoli, ten skin-boosting vitamins (hence the V10), vitamin tree fruit extracts, peptides, and is suitable for sensitive skin. I have sensitive, combination, acne-prone skin. It was non-irritating and didn't provoke a breakout. I wouldnt mix this with your acne treatments or actives (high % vitamin C or A or derivatives). Just use the lotion on the nights you are giving your skin a break and want added hydration and a nutrient boost. This will limit the likelihood of a poor product interaction which may compromise your skins moisture and acid barrier. Mild scent (faint hints of citrus); nothing overpowering or unpleasant; doesn't linger. Woke with moisturized skin without any adverse reactions. However, I don't like the weight and sticky feeling on my skin. I will continue to use this up, as it does make me appear hydrated and nourished. I just don't enjoy the stickiness/tacky residue gluing me to my pillowcase.
