New, unopened. Purchased three months ago, but switched to a different serum. Prevents skin irritation. This highly moisturizing serum addresses the skin's crucial moisture-retaining structure. Contains the active ingredient "Heparinoid HD." Recommended for those with dry skin prone to irritation. Alcohol-free, fragrance-free, and colorant-free.

Alcohol-free, fragrance-free, and colorant-free. I want to sell it cheaply. The compact costs about 500 yen, so I can't go any lower than that. If it's around 100 yen, it's cheaper than the retail price.
