Photodynamic therapy based on E technology outputs blue light, red light and high-frequency electromagnetic waves, which accurately acts on sebaceous glands, acne and other target tissues. Blue light is used to kill Propionibacterium acnes, and the combined action of red light and high-frequency electromagnetic waves reduces the activity of sebaceous glands.

Compared with the previous blue light, blue-red light and strong light, the current E-technology (El-not s) has greatly improved the curative effect in the treatment of seborrheic dermatoses such as acne, rosacea and seborrheic dermatitis, and ordinary patients can see obvious effects once. It is worth mentioning that E-technology (El-not s) is also very effective in treating large pores, blackheads, white-headed acne, seborrheic skin, rosacea erythema, papules and telangiectasia.
