Ephelis or Sunburn

In this particular variety of discoloration the pigment deposit is excited by the sun's rays. Sunburn consists of little dots, the size of pins' heads, which appear upon the parts of the body exposed to the influence of the sun, and are seen mostly in lymphatic subjects with delicate skins. Temporary benefit accrues from the use of local applications strong enough to cause exfoliation of the corneal cells. A one per cent, solution of mercuric bichloride and a ten per cent, solution of calcium chloride are the lotions most commonly used.
