Sun-induced age spots (lentigines) clear well with Q-switched Nd:YAG laser + topicals. By Dr. Reena Sharma, MD Dermatology.
Age spots (solar lentigines) are well-defined brown spots from cumulative sun damage — the most common visible sign of photoageing. Treatment is straightforward: 3 to 4 sessions of Q-switched Nd:YAG laser + topicals + lifelong SPF.
Treatment
Q-switched Nd:YAG 1064nm laser targets pigment without damaging surrounding skin (safe for Indian skin tones). Spots typically darken transiently after treatment, then flake off over 7 to 10 days. 3 to 4 sessions, 4 to 6 weeks apart.
Topical retinoid + vitamin C + niacinamide prevents new spots and accelerates clearance. Strict daily SPF 50 is non-negotiable — new spots form quickly without sun protection.
Cumulative sun damage. UV radiation triggers melanocytes to produce extra pigment in localised spots that grow over years. Genetics influence susceptibility.
Are age spots cancerous?
No — solar lentigines are benign. However, any pigmented lesion that grows rapidly, has irregular borders, or multiple colours should be assessed for atypia. We use dermoscopy on consultation.
How are they treated?
Q-switched Nd:YAG laser is the gold standard for Indian skin — typically 3 to 4 sessions clear most age spots. Cryotherapy works too for limited spots. Topical retinoid + vitamin C + SPF for long-term prevention.
Will they come back?
New age spots can form with continued sun exposure. Strict daily SPF 50 prevents new spots and maintains treatment results.
How is this different from melasma?
Age spots are well-defined, individual brown spots from sun exposure. Melasma is hormonal, larger blotchy patches usually on cheeks. Different cause, different treatment.
When are dermal age spots harder to treat?
Deeper-pigment spots need more sessions. We assess depth via Wood lamp on consultation and adjust the protocol.
