So many reasons: Sun exposure contributes to break down of elastic tissue and collagen in skin leading to skin wrinkling prematurely. It also causes pigmentary changes: freckles, solar lentigos referred to as "liver or age spots" and is a major contributor to skin cancer and precursors to skin cancer (actinic keratoses) sun avoidance and sun precautions (sun screen, protective clothing) is best for youthful skin.

Burns, cancer risk: Excess sun exposure can harm the skin immediately (dry, itchy skin, or full sunburn) and over the long-term (more wrinkles, increased risk of skin cancers). The fairer your skin tone, the more sensitive you may be, but even very darkly pigmented skin can still be damaged by too much sun. Always use a good sunscreen (spf 15 or more) when enjoying the sunny outdoors, and you should be protected.

Reaction : The sun reacts with the melanin already in your skin. Depending on your genetic makeup and race will determine how dark you will get. You have to have enough of the melanin in you skin for it to react to the sun and to get tan or darker skin tone. Some people only blister and peel but do not have enough melanin to actually tan.

DNA damage: Prolonged sun exposure, especially during midday hours, can cause dna damage to cells in the skin. This results in photoaging and can eventually lead to the development of skin cancer.
