Introducing PD-13 Therapy to the treatment room

KRX PD-13 Therapy is a highly targeted, non-medicated photodynamic therapy especially effective for treating stubborn acne, actinic keratosis, and conditions like rosacea—all powered by the synergy of a MAL-HCl photosensitizer and red light activation.

It's a photosensitizing product containing 13% Methyl Aminolevulinate HCl (MAL-HCl). When applied to skin, it becomes activated by red light therapy, producing reactive compounds that help kill acne-causing bacteria and reduce sebum production.

MAL-HCl, upon red light exposure, generates reactive oxygen species—these target inflammatory pathways, bacterial overgrowth, and sebaceous gland activity

• Clears Acne at the source by targeting acne-causing bacteria and overactive sebaceous glands for long-term breakout control.
