Red Light Therapy for Acne Vulgaris
Acne vulgaris is the most common skin condition, caused by sebaceous gland overactivity, P. acnes bacterial colonization, follicular keratinization, and inflammation. It affects face, chest, and back.
Prevalence: Affects up to 85% of adolescents and 12% of adult women
How Red Light Therapy Helps
Blue light (415nm) kills P. acnes bacteria via porphyrin activation, while red light (633-660nm) reduces inflammation and promotes healing. The combination addresses both bacterial load and inflammatory response.
