Solar Lentigo ("Sun Spots")

Description

• A solar lentigo is a flat, brown, tan, or black spot on the skin caused by long-term sun exposure. These spots are very common as people get older, especially on areas frequently exposed to the sun such as the face, hands, shoulders, arms, and upper back.

  Solar lentigines are benign (non-cancerous) and do not turn into skin cancer. However, because they can sometimes resemble other pigmented spots, it’s important to have them evaluated during a skin exam to confirm the diagnosis.

  Many people choose to treat solar lentigines for cosmetic reasons. Options may include topical creams, chemical peels, laser therapy, or cryotherapy to lighten or remove them. Sun protection is essential to prevent new spots from forming.

When should I come in?

You should schedule a visit if:

• A sun spot changes in size, shape, or color.

• The spot has irregular borders, multiple colors, or asymmetry (to rule out melanoma or atypical moles).

• The area becomes itchy, painful, or bleeds.

• You are uncertain whether the spot is a benign sun spot or a precancerous lesion (like actinic keratosis) or melanoma.

• You want to explore cosmetic treatments for lightening or removing sun spots (e.g., cryotherapy, chemical peels, laser, or prescription creams).

Because sun spots are caused by cumulative UV exposure, their presence may also indicate increased risk for other sun-related skin conditions, including skin cancers. Regular skin exams help ensure early detection and peace of mind.

How are they treated? 

Solar lentigines are harmless, so treatment is not medically necessary. However, many people choose to have them lightened or removed for cosmetic reasons. Common treatment options include:

• Topical Creams: Prescription or medical-grade creams (such as hydroquinone, retinoids, or other lightening agents) can gradually fade spots over time.

• Cryotherapy (Freezing): A quick in-office treatment using liquid nitrogen to remove the pigmented cells.

• Chemical Peels: Medical-strength peels that help lighten pigmentation and improve overall skin tone.

• Laser or Light Therapy: Specialized lasers target pigment in the spots, often providing the most noticeable results.

• Microdermabrasion: A gentle exfoliation treatment that can improve skin texture and reduce the appearance of sun spots.

Because new spots can form with sun exposure, daily sunscreen use and protective clothing are key to preventing future sun damage.
