Early effects:

a) Sun burn, redness, soreness, swelling, blistering and boild

b) Tanning (formation of brown melanin pigmentation on exposed area)

c) Hyperplasia – thickening of all skin layers but particularly of the dead horny layer.

Late effects:

a) Ageing – degenerative changes of chronically exposed skin, apparent as loss of substance, dryness, coarseness, brown blotchiness, yellowing, wrinkling and laxity, with large blackheads and whiteheads.


b) Precancers and Cancers – persistent rough patches or irregular slowly growing lumps or sores, sometimes colored brownish or reddish.

Protection from Sun:

Usage of sunscreens or suntan lotion is an effective way of preventing skin damage due to sun rays. There are basically two types of sunscreens – absorbent and reflectant. Absorbent sunscreens are available with pharmacists and work by absorbing harmful UV rays before they reach the skin surface and dissipate them as heat. They are effecting with UVB rays but they are irritable to skin on most people. Reflectant sunscreens contain zinc oxide or titanium dioxide which are more medicinal and are used to apply as thick patches on lips and nose that are prone to sun burning. Sunscreens are gauged using their sun protection factor (SPF).

3. Ringworm

Eye infection – Conjunctivitis

It is the commonest eye infection of all producing a sticky discharge that glues the eye lids together. It spreads from person to person very fast through contact or touch of the fluid secretion.
