Sun Spots and Age Spots: Clearing the Markers of UV Damage

Sun spots and age spots are discrete areas of UV-driven pigmentation. They respond well to IPL and laser — and recur without consistent sun protection.

Pigment & Redness

Sun spots are among the most treatable pigmentation concerns. IPL clears most of them in one or two sessions.

What It Is

Sun spots (solar lentigines) and age spots are flat, discrete areas of brown or tan pigmentation that develop from cumulative UV exposure. They represent localized areas where melanocytes have been overactivated by chronic sun exposure and have produced persistent excess melanin. They're among the most common signs of photodamage and are distinct from freckles (genetic), melasma (hormonal), and PIH (inflammatory).

Why Patients Seek Treatment

Patients come in about sun spots when they become noticeable in photos or when the overall quality of the skin has started to look aged in a way that bothers them. Many are surprised by how quickly and completely they can be cleared.

UNDERSTANDING THE SCIENCE

Sun spots form from decades of UV-driven melanocyte overactivation — and keep forming without daily SPF.

01

What Causes It

Sun spots are caused by UV radiation overactivating melanocytes in specific areas of chronic or intense sun exposure.

Cumulative UV damage: Every unprotected sun exposure adds to the melanocyte overactivation that eventually produces visible spots. Spots that appear in the 40s and 50s often represent decades of accumulated exposure.

High-intensity exposures: Sunburns and intense UV exposures — particularly those that occurred in childhood and early adulthood — contribute disproportionately to lifetime melanocyte overactivation.

Genetic predisposition: Lighter skin tones are more prone to visible sun spot formation. However, all skin tones accumulate UV damage — it's more visible in lighter complexions.

02

Common Signs

Patients with sun spots typically notice:

  • Flat, brown or tan spots on the face, hands, shoulders, or chest
  • Spots that have darkened or multiplied over the years
  • A mottled or uneven complexion quality in areas of high sun exposure
  • Spots that are darker in summer and slightly lighter in winter
  • An overall complexion that looks older than the patient expects in certain lighting
03

Why It Changes Over Time

Sun spots accumulate gradually and become more visible through the 40s and 50s as decades of UV exposure compound. New spots continue to form with ongoing sun exposure even after treatment — which is why sun protection after treatment is essential and why many patients schedule annual maintenance sessions.

Beyond the surface pigment, patients with significant sun spot burden have typically also accumulated structural UV damage — collagen loss, texture changes, and early photo-aging that goes beyond discoloration alone.

04

How It's Commonly Addressed

Sun spots respond to treatments that selectively target excess melanin.

  • IPL: The most efficient treatment for discrete, well-defined sun spots. Light energy is selectively absorbed by melanin, causing the spot to darken briefly before flaking off. Results are visible within 1–2 treatments.
  • Chemical peels: Address broader areas of diffuse sun damage and uneven tone alongside discrete spots. Produce progressive improvement across multiple sessions.
  • Laser resurfacing: Treats both surface pigment and the structural UV damage beneath it. Appropriate for patients with significant photodamage who want comprehensive improvement in both tone and texture.
  • Topical maintenance: Vitamin C, retinoids, and daily SPF prevent new spot formation and maintain treatment results.

We clear the existing damage. We also have the SPF conversation.

At CAMI, sun spot treatment is matched to the degree and distribution of damage. Isolated spots respond quickly to IPL. Patients with significant diffuse damage across the face, chest, or hands often benefit from a layered approach that addresses both the surface spots and the underlying photodamage driving them.

We're also direct about the SPF conversation. Treatment clears what's there. SPF prevents what's coming. Both are part of the plan.
