One embodiment of the present invention relates to a composition for treating acne and a method for producing an acne treatment agent using the same.

Although skin diseases do not interfere with life, they occur frequently, and modern people are becoming more and more common due to various causes, climate, and stress.

In particular, acne is an intractable skin disease caused by fungal and bacterial infections, which requires a long term treatment period and is difficult to treat.

As a method for treating acne, hormones and antibiotics for suppressing sebum production are prescribed. These methods are somewhat effective in the prevention and treatment of acne, but side effects are questioned in terms of satisfactory efficacy and skin safety.

In the case of hormone drugs, it may cause adverse effects in long-term administration such as erythema and dryness of skin. Antibiotics such as benzoyl peroxide and retinoic acid cause problems of carcinogenicity and contact dermatitis have. In addition, tetracyclin, erythromycin, and clindamycin have been used for the treatment of acne, but it has been reported that there is a possibility of the occurrence of resistant bacteria.

On the other hand, photodynamic therapy (PDT) is a curative method such as a chemotherapeutic agent that can treat lesions without surgery using a photosensitizer with selectivity and photosensitivity to various lesions. For example, the photo-sensitive material is administered to a subject by intravenous injection, and a suitable light is irradiated to activate the photo-sensitive substance to convert oxygen molecules into singlet oxygen or to create new radicals The lesion is selectively attacked and collapsed.

As such photosensitizers, porphyrin compounds are representative, and porphyrin compounds extracted from dips, mulberry leaves, and green algae have spectroscopic properties suitable for use as photosensitizers, and red light having a relatively high cell permeability (700-900 nm) is known to be capable of efficiently generating the electron transferring property and thus the excited state.
