Rosa Roxburghii Handmade Soap is a 100 g cleansing bar made with Vitis vinifera grape seed oil and rosa roxburghii extract. It is used by wetting the skin with warm water, creating a rich foam by hand or foaming net, gently massaging over the skin and rinsing thoroughly. The material emphasizes the difference between handmade soap and industrial soap, highlighting retained plant oil nutrients, fine mild foam, moisturizing comfort and a non-tight feeling after cleansing. Rosa roxburghii and grape seed oil provide a natural antioxidant and soothing product story. For upload use, it should be described as a plant-based handmade soap for cleansing and nourishing care, without claiming to treat acne, dermatitis or skin disease.
