Changes in skin coloration are a normal part of the aging process. But many people find brown spots, also known as “liver spots” or “age spots”, to be unattractive. These spots that often appear on the back of the hands are caused by sunlight exposure or chronic bruising of the skin.
You need to give more details about the brown spot. Is it a freckle or is it a mole? How big is the spot? If it is a mole, you should visit a dermatologist.
Prevention is the easy part—apply sunscreen to your hands, arms, face, and scalp (if not covered with hair) every day, whether you plan to go outside or not. You see, sun damage comes in two forms: UVA and UVB. Ultraviolet A rays are known as “aging rays”; UVA sunlight makes up 90-95% of all sunlight that reaches the earth’s surface. It penetrates windows of houses and cars; it gets through clouds; it’s present 365 days a year. Even more troublesome is the fact that UVA exposure is “silent”. You don’t get a tan or sunburn from UVA exposure. UVB rays, also called “burning rays,” cause tanning and burning of the skin, so you know when it’s happening. Enough said? So from this day forward, you’ll apply sunscreen with an SPF of 30?
Men and women desiring to completely eliminate brown spots should consider visiting a skin care provider. They can offer chemical peels, microdermabrasion, intense pulsed light therapy, and several types of laser resurfacing procedures which can remove even the most stubborn of brown spots. Chemical peels usually involve an application of glycolic acid to the epidermis. When this layer blisters and peels, the new layer of skin develops, unblemished by signs of aging.
Laser is the best way to remove moles. It is good that you have visited a doctor since moles can be the symptoms of other problems. Since that is not the case, simply get them removed through laser.
Sunscreen, protective clothing, and sunglasses help prevent further sun damage. Exposure time in the sun should be limited and seek shade when outdoors. Try to avoid outdoor activities between 10 am and 3 pm, when the ultraviolet rays are strongest. See a dermatologist yearly for a skin examination to check for any abnormal moles or skin cancer.
