Understanding and Treating Age Spots: Complete Guide

What Are Age Spots?

Solar lentigines—flat, tan/brown/black spots on sun-exposed skin (face, hands, shoulders, arms). Caused by cumulative UV exposure + aging melanocyte dysregulation. Benign but a common cosmetic concern.

Treatment Ladder (Least → Most Invasive)

1. OTC Topicals (8–12 weeks):
   • Retinoids (adapalene 0.1%, retinol): increase cell turnover.
   • Hydroquinone 2%: inhibits tyrosinase (max 3–4 months, then break).
   • Vitamin C, niacinamide, azelaic acid, glycolic acid: brighten gradually.
2. Prescription Topicals:
   • Hydroquinone 4% + tretinoin + fluocinolone (triple combo).
   • Tazarotene, cysteamine.
3. In-Office Procedures:
   • Laser/IPL: Q-switched Nd:YAG, picosecond, fractional non-ablative. 1–3 sessions. Gold standard.
   • Cryotherapy: Liquid nitrogen. Best for isolated spots. Risk: hypopigmentation.
   • Chemical Peels: TCA, glycolic, Jessner's. Improves overall tone + spots.
   • Microneedling + Topicals: Enhances penetration.

Prevention: The Only Cure

• Broad-spectrum SPF 30+ daily—rain or shine.
• Reapply every 2 hours outdoors.
• Wide-brim hat, UPF clothing, seek shade 10 AM–4 PM.
• Antioxidant serum (vit C/E/ferulic) under sunscreen.

When to See a Dermatologist

• Spot changes: asymmetry, border irregularity, color variation, diameter >6mm, evolving (ABCDE).
• Rapid growth, bleeding, itching.
• Uncertain diagnosis—rule out melanoma, seborrheic keratosis, actinic keratosis.

Consistency with sun protection beats any laser. Start today.
