Understanding and treating solar lentigines
What Are Sun/Age Spots?
Flat, brown, gray, or black spots on sun-exposed areas from accumulated UV damage. More common after age 40, these spots result from years of sun exposure causing melanin to clump together in certain areas.
Common Characteristics
- Appearance: Flat, oval, tan to black, freckle-size to 2 inches
- Locations: Face, hands, shoulders, chest, forearms
- Who Gets Them: Adults 40+, fair skin, sun exposure history
What Causes Sun Spots?
Years of UV exposure accelerate melanin production, causing pigment to clump together. Risk factors include cumulative sun exposure, fair skin, sunny climates, and outdoor activities/occupations.
How Touch Bright & Clear Works
Kojic Acid: Blocks melanin production, breaks down existing deposits
Tranexamic Acid: Prevents UV-induced pigmentation, stops darkening
Azelaic Acid: Selectively targets abnormal pigment, gentle exfoliation
Niacinamide: Prevents melanin transfer, repairs UV damage
