Which technique is used to improve blood circulation in the skin?

Petrissage is a massage technique characterized by kneading, rolling, and squeezing movements that target the muscles and tissues beneath the skin. This technique is particularly effective in improving blood circulation because it helps stimulate the blood vessels, encouraging increased blood flow to the area being treated. Enhanced blood circulation brings more oxygen and nutrients to the skin, promoting healthier skin appearance and assisting in the removal of toxins.

While the other techniques mentioned can have beneficial effects on the skin, they do not specifically focus on enhancing circulation in the same way that petrissage does. For example, desincrustation is primarily used to deep clean the skin by softening and removing impurities, while exfoliation involves the removal of dead skin cells to promote surface renewal. Massaging, though beneficial for relaxation and general blood flow, does not specify the targeted techniques and benefits that petrissage offers in terms of circulation enhancement. Thus, petrissage is recognized as the technique that effectively improves blood circulation within the skin.
