Is there any benefit of Gua Sha in removing melasma?

Gua sha offers certain benefits for melasma. By stimulating meridians and the skin, Gua sha can improve circulation of blood and qi, achieving effects of promoting blood circulation to remove blood stasis and regulating yin and yang. For patients with melasma, Gua sha stimulates acupoints and meridians, thus unblocking meridians and regulating internal blood and qi circulation, helping alleviate skin problems caused by poor circulation. Meanwhile, Gua sha can also enhance local blood circulation, increase blood flow, improve the skin's microenvironment, reduce pigmentation, and help lighten melasma. Additionally, Gua sha promotes facial metabolism, accelerating the metabolism and excretion of melanin, further fading pigmented spots. It is important to note that Gua sha alone should not be considered the sole treatment for melasma; it should be combined with other therapeutic approaches for comprehensive management.
