Yes, I tried it first when I bought sensitive skin. I bought it without any discomfort or allergies. Ba said that redness may occur because the mask is thick and well wrapped. If it is used for too long, the phenomenon of "false allergy" will appear, and it will disappear after washing 10 minutes. Her products are pure plants and very gentle, so you can buy them with confidence. I bought it and used it twice, and the effect was good. There is a transparent stick in the box. Apply a proper amount of mask evenly on the face, wait 10 minutes and then massage according to the massage method in the instructions, especially on the parts with lymph glands such as behind the ear and sunken chin, which not only drains water, but also has a good effect of eliminating fatigue. After finishing this face-lifting mask, I really feel that the facial lines are tightened and the chin will naturally become sharp.
