Potassium titanyl phosphate
Potassium titanyl phosphate
A potassium titanyl phosphate (KTP) laser emits green light and has a higher penetration coefficient than blue light. This laser operates based on porphyrin activation and a photothermal effect on the sebaceous gland. However, the KTP laser effect on acne is not long-lasting and may lead to erythema, edema, and transient crusting. Therefore it is not widely used for the treatment of acne.30
