Age spots, also known as senile lentigines, are lipofuscin pigmented patches that develop on elderly skin. Though typically associated with seniors, many middle-aged people develop them prematurely due to sun exposure, improper diet and other triggers. An article published in Taiwan’s New Life News emphasizes that age spot prevention should start in middle age to avoid their early appearance.

Age spots usually emerge after the age of 50 on sun-exposed areas including the face, ears, neck, chest, upper back, hands and feet, with clear boundaries. They start as flat discolorations and gradually thicken into rough brown-to-black papules or plaques. After 60 to 70 years old, their quantity and size tend to increase with advancing age.

Multiple factors contribute to their formation: gradual decline of skin function, weakened free radical clearance, endocrine disorders, poor visceral function, sluggish blood circulation and long-term ultraviolet exposure.

Dietary & Lifestyle Prevention Tips

1. Control dietary fat intake and eat plenty of fresh fruits and vegetables, especially tomatoes, citrus fruits, lemons, persimmons, carrots and pumpkins.

2. Supplement vitamin E, which inhibits the oxidation of unsaturated fatty acids and reduces lipofuscin pigment formation inside the body.

3. Boost facial muscle activity: chew food slowly and thoroughly to boost facial blood circulation and skin metabolism.

Core Sun Protection Measures Recommended by Experts

The key to preventing age spots is avoiding prolonged intense sunlight and harsh skin irritation.

- For seniors, stay out of direct sun between 10 a.m. and 2 p.m. when UV rays are strongest; if sunbathing, prioritize the back of the head and back.

- Sun protection should be maintained starting from youth. It not only prevents sunburn, delays skin aging and pigmentation, but also lowers the risk of skin cancer.
