Refresh your skincare routine with Anua Vitamin C Blemish Serum Mask 25ml — a brightening sheet mask designed to help improve the look of dull, uneven-looking skin while keeping skin moisturized. Current retailer listings describe it as a Vitamin C + Vitamin E serum mask, and some stores also list it under the earlier naming Green Lemon Vita C Blemish Serum Mask. YesStyle notes that the renewed version changed the product title and packaging, while the product remains a brightening, moisturizing sheet mask.
