A smooth-edged tool drawn firmly along oiled skin, in one direction, until the tight muscle underneath starts to give. It brings up a red mottling called sha, and that fades in a few days.

No. Facial gua sha is light and cosmetic. Ours is firm, done on the neck, back and legs, and aimed at tight muscle.

不一样。面部刮痧手法轻，以美容为主。我们的刮痧力度较大，刮在颈部、背部和腿部，针对的是紧绷的肌肉。

It is firm and can feel intense over a tight spot, but it should not feel sharp. Say the word and we ease off.

力度较大，刮到紧绷的地方会比较强烈，但不应该是刺痛。您说一声，我们就放轻。

A few days, sometimes up to a week, and it is only tender for a day or so. Keep the area covered and skip hard exercise that day.

几天，有时长达一周，通常只会酸痛一天左右。当天请遮盖保暖，避免剧烈运动。
