Skin changes with age. Look at the baby’s skin. It is soft and smooth. Look at the grandmother’s skin. It is wrinkled.
Skin can have freckles. Some freckles are caused by the sun. They show that the skin is sensitive to the sun’s rays.
The sun’s rays are strong. They can damage your skin. Are you going outside? Remember to wear sunscreen. It protects against sunburns.
