Dry brushing involves using a body brush on dry skin to exfoliate, stimulate circulation, and promote lymphatic drainage. It's a gentle massage with firm strokes, often done before showering, and can help to remove dead skin cells and improve skin texture. 
Benefits:
Reduced Appearance of Cellulite: While not a cure, dry brushing can make cellulite appear less noticeable. 
Exfoliation: Helps remove dead skin cells, revealing smoother, brighter skin. 
Improved Circulation: Can increase blood flow and potentially reduce the appearance of cellulite. 
Lymphatic Drainage: May help the lymphatic system drain fluid and potentially boost the immune system.
