Pigmentary Disorders – Lentigenes
Lentigines are also known as sun spots, freckles or liver spots. They are harmless, flat, brown discolorations of the skin, and are caused frequent sun exposure on the skin.
They are commonly found on the backs of the hands, necks and faces of people over 40 years of age. These brown spots are harmless and do not need to be treated unless they are changing in appearance or getting bigger in size.
Normal brown spots can be 1 cm or greater in diameter. Use of sunscreen and sun avoidance is the best way to prevent the development of more brown spots. This will not prevent the occurrence of brown spots due to sun damage done at earlier stages of your life.
Methods used to remove these brown spots include:
- liquid nitrogen application
- laser therapy
- chemical peels
- alpha hydroxy acid gel and beta hydroxy acid gel
- topical vitamin C treatment
- topical vitamin C used in combination with alpha hydroxy acid
- Retin-A cream to lighten the spots
- Retin-A cream used in combination with alpha hydroxy acid
