Pseudocatalase Cream

Vitiligo is a spontaneous irregular depigmentation of skin. Patients with vitiligo have low catalase levels in their epidermis with high levels of hydrogen peroxide. Pseudocatalase cream is an externally applied UVB-activated product that can lead to recovery of the oxidative damage in the epidermis and remarkable repigmentation.

Topical Phenylalanine

Melanocytes are still present in long-standing (> 25 years) depigmented skin of patients with vitiligo. L-phenylalanine uptake and turnover in the pigment forming melanocytes is vital for initiation of melanogenesis.
