Besides the face, where else do sunspots tend to appear?
Solar lentigo is a mark of... Photoaging Therefore, wherever the patient likes to expose their skin to the sun, that's the target. The main areas that doctors frequently see and can treat include:
- Back of hand and arm: This is the most obvious sign of aging; it becomes very noticeable if you drive in the sun frequently.
- Neck and décolletage: For people who like to wear wide-necked shirts.
- Back and shoulders: For beach lovers, wear a swimsuit or a tank top.

Are the techniques for "peel" or "cauterize" sunspots different depending on the location?
There's a slight difference, patient. Our main treatments involve... Co2 lasers หรือ Pico Laser In removing pigment, however, the... "thick" The skin texture is different in different areas.
- Facial skin: The skin is quite thin and delicate, so the doctor will use precise energy to avoid damaging the skin too deeply.
- Body skin (arms/back/hands): The skin in this area is thicker, and It has fewer sebaceous glands than the face. This can slow down wound healing, so the doctor may need to adjust the energy levels accordingly to prevent scarring or post-operative hyperpigmentation (PIH).
What patients need to know! The importance of "scabbing duration" (very important).
I want to highlight this in bold because patients often get worried when the procedure is done on their body and takes a long time to heal.
- Facial area: The wound will heal quickly, and the scab usually falls off completely within a short period. 5 – 7 days Because the face has a high blood supply and many sebaceous glands.
- Torso/arms/hands: The wound will heal much slower; the scab may last for a long time. 2-4 weeks Exactly. Therefore... Stay calm and absolutely do not scratch or pick at it. Just wait for it to fall off naturally.
Post-treatment care…to prevent freckles from returning.
Peeling removes old pigment, but if the patient continues to be exposed to sunlight, the freckles will return.
- Apply sunscreen generously: Not just the face, but... Hands, arms, neck You have to apply it all over.
- Avoid exfoliating: The skin is still delicate right after the scabs have fallen off. Avoid scrubbing that area for 1 month. Please focus on applying moisturizer to hydrate your skin instead.
