This advanced device is used to treat vitiligo, alopecia areata, psoriasis, palmoplantar pustulosis, and atopic dermatitis. For refractory skin diseases, the clinic also provides treatment with biological agents, and has been offering Dupixent, a new treatment for atopic dermatitis, since 2019. The clinic focuses on alopecia treatment, providing the AGA (androgenetic alopecia) medication dutasteride for 6,600 yen per month. In terms of facilities, two ceiling-mounted medical air purifiers are installed, removing over 99.9% of viruses and bacteria to prevent nosocomial infections.
