Final answer:
Excessive sun exposure can lead to skin damage, including premature aging, wrinkles, and an increased risk of skin cancer. It is essential to use protective measures like sunscreen to prevent these outcomes.
Step-by-step explanation:
Factors that lead to skin damage and are no longer advised include excessive sun exposure, regular use of harsh chemicals, and lack of proper skincare routine. Excessive sun exposure can damage collagen fibers, accelerate the aging process, and lead to the formation of wrinkles. It is associated with sunburn, skin cancer from repeated exposure, and studies show a link between overexposure to the sun at a young age and melanoma later in life. These risks underscore the importance of wearing sunscreen with a high SPF, protective clothing, and avoiding prolonged exposure to the sun.
