What it is
A new desert lotion designed to tackle extremely dry environments. It focuses on the fact that dryness and UV rays cause moisture loss, leading to shriveling of stratum corneum cells and loss of firmness. Learning from the sleeping midge, which survives even in extremely dry environments, this three-pronged moisture-retention approach replenishes stratum corneum cells that shrink as dryness progresses, providing sustained moisture even in dry, desert-like environments. This lotion leaves skin feeling moisturized and firm, just like after a lotion mask. Available in three types (K, S, and T) to address the underlying causes of skin concerns. Formulated with est's proprietary Ectobiosis (moisturizing: ectoine, diglycol guanidine succinate, trehalose, glycerin). Smooth, viscous texture for a refreshing, hydrating feel. Aquatic floral scent. *This product is a refill; the original product is not included.

This is a repeat purchase. Unlike the main product, the refill is quite simple (lol). I wonder if K might be better for people who get acne occasionally or have combination skin. It feels like it penetrates and softens the keratin. It's not sticky but moisturizes, so it feels very pleasant to use.
I was interested in this product after reading the reviews. It's very moisturizing and doesn't dry out my skin even after a while. I'll consider using it again after I've finished one bottle.
It's a slightly thick lotion. It has no odor, and I use it together with other serums from the series, and it doesn't irritate my skin. I bought it after watching Hiro's YouTube video. The next morning, my skin feels firmer. It's not dry, it's moisturized.
