What beauty salons usually do is to prepare soft films on the spot, that is, soft membrane powder with different effects, such as whitening and hydrating. Add water to make a thin paste, and then apply it to the face, which can be removed in about 15 minutes. I have done it before, and I feel that the hydrating effect is really good. In fact, you can buy your own soft membrane powder and mix the water yourself. You can also choose different pure dew to match according to skin type. Rose Pure Dew is hydrating and whitening, lavender can control oil and calm skin, and chamomile is aimed at sensitive skin. But it's not convenient for beauty salons, and it often drips everywhere when smearing, but the cost is much lower than that of beauty salons!
