Though majority of the people like the light of the sun and its warmth but spending too much time under the sun can cause a serious damage to the skin especially in case of sensitive skin. The extra exposure to sunlight dehydrates the skin, cause sagging, sun burns, pigmentation and skin discoloration.
When the skin is exposed excessively to sun in early age, it makes a person look much older than his or her actual age. The excessive sun exposure in early age causes premature wrinkles and damage to the skin. This condition is known as ‘photo ageing’. It results in rough, coarse and dry skin with freckles and skin discoloration accompanied by leathery skin and deep wrinkles which is unlike the natural ageing process.
UV rays of sun can thicken or thin the skin stimulating the formation of fine lines and wrinkles. It makes skin pale and vulnerable to bruising, tearing and injuries. The skin sags and loses its elasticity due to the breakdown of elastin fibres within the skin. This gives rise to the coarse and deep wrinkles.
The effects of Sun Damage
- Skin dryness: The skin exposed to sun continuously loses its moisture and the essential oils. This makes the skin dry and flaky causing premature wrinkles.
- Sun burns: When the skin is directly exposed to the UV radiations, it causes skin injuries. The skin reddens in case of mild sun burns while in severe cases tiny fluid filled bumps or large blisters can form on the skin.
- Telangiectasias: in this condition the tiny blood vessels become more apparent due to sun damage specifically on the face. The spots present on the sites where melanocytes are damaged become more visible. Melonocytes produce melanin within the skin which is responsible for giving colour to the skin. Due to sun damage, the condition of those pigmented areas become worse leading to formation of freckles, age spots, liver spots and in some cases white spots.
- Skin bumps or Actinic keratosis: the skin rashes starts to appear on the skin. It can take the form of moles, wart-like seborrheic keratoses and actinic keratoses. These crusty bumps on skin are a warning sign of skin cancer. Almost 10 %-15% of the actinic keratoses, eventually develop into squamous cell carcinoma.
