【Contains high-quality domestic horse oil】 Contains "horse oil", which is extremely close to human sebum, known as a "universal oil". 【Foot Exfoliation Product】 The sock-shaped plastic bag contains a solution mainly containing AHA. Excess keratin on the soles of the feet can be easily peeled off with just one soak. Similar to facial exfoliation products, but it requires about 40 minutes of soaking, so it penetrates the keratin on the soles of the feet, which is much thicker than the face, allowing for exfoliation of the soles of the feet without any pain.
