NMN for Skin Photoaging: What the Evidence Actually Shows
What is Skin Photoaging?
Skin photoaging is the cumulative damage from UV exposure, producing wrinkles, pigmentation, loss of elasticity and broken capillaries. It is largely preventable with sunscreen.
NMN relevance: the published evidence
Mechanistic work shows NAD+ supports DNA repair (PARP) and sirtuin activity, both relevant to UV-damaged skin. No human RCT has tested oral NMN with validated dermatology endpoints (wrinkle scores, biopsy markers). Daily SPF, retinoids and vitamin C have far stronger evidence.
Questions to ask before supplementing
No oral dose validated for skin endpoints.
Contraindications and red flags
NMN is not a substitute for sunscreen.
Bottom line for Malaysian patients
NMN is not registered with NPRA as a treatment for any specific condition; it is sold as a general health supplement. If you have skin photoaging, use this page as a question list for a registered medical practitioner before adding NMN to existing therapy. Read our safety guide for full red-flag context.
