Photodynamic Therapy

Photodynamic therapy uses a light-activated drug, or photosensitizer, that is administered systemically or topically. When a specific wavelength of light is applied to the target area, the drug produces a form of oxygen that kills nearby cells. Its relevance to healthspan is based on its experimental potential as a targeted senolytic therapy to selectively destroy dysfunctional senescent cells, which are known drivers of aging.

Verdict

A powerful clinical tool, but highly experimental and risky for longevity.

Protocol

• Experimental protocols are exploring systemic or localized treatments to clear senescent cells, but no standard healthspan protocol exists.

Flags

• Primarily a clinical treatment for cancer and dermatology, not a standard healthspan therapy.
• Causes extreme photosensitivity for days or weeks post-treatment, requiring strict sun avoidance.
• Must only be performed by a qualified medical professional in a clinical setting.
• Risk of significant pain, swelling, scarring, and blistering at the treatment site.
