How to get rid of sunspots?

In response to ultraviolet (UV) light from the sun, the skin develops flat, brown pigment changes called Sunspots. Melanin builds up in skin cells as a result of UV exposure, darkening the skin.

Our hands and face are the most frequently affected skin areas by this hyperpigmentation, but it can also emerge on any exposed body part such as arms, shoulders, back, chest, and feet.

Sunspots go by many different names, namely, age spots, solar lentigines, lentigo senilis, and liver spots. The light brown to black pigmentation of varied sizes that normally develops in persistently sun-exposed skin is referred to by the following popular and medical terminology. These are harmless spots and they can’t become skin cancer.

UV light from the sun increases the growth of melanocytes, which are skin cells. The pigment termed melanin, which is made by melanocytes, gives the skin its color.

People may develop hyperpigmented (hyperpigmented) or hypopigmented (hypopigmented) skin regions when melanin production is disrupted. Hyperpigmented skin lesions are called sunspots.

Sunspots are not and never develop into cancer. But other people could find these skin imperfections offensive. In order to minimize the appearance of sunspots and boost their self-esteem, they might consequently seek treatment. 

They can be eliminated for cosmetic appeal, but leaving them alone has no health hazards. Although most treatments are secure, some could result in short-term irritation and redness. Discuss the potential dangers of each treatment with a doctor.

Causes 

Sunspots have an unknown specific cause, according to researchers. They are aware that UV rays induce melanin to build up in the skin, but they are unsure of the exact mechanism. They postulate that a number of growth factors, inflammation, and decreased melanin elimination all have a role.

Sunspots can affect everyone, although those with fair complexion, red hair, and persons over 40 are more likely to get them. Sunspot development is prone to risk factors such as frequent UV exposure, tanning beds, and a history of severe sunburns.

Genetics might also be important. People are more likely to get sunspots if their family has a history of it. 

How to prevent Sunspots?

• Limiting your contact with UVA and UVB radiation is a way to stop sunspots from developing. 
• Broad-spectrum sunscreen should be used before stepping out.
• At least an SPF of 30 is a must.
• As instructed, reapply sunscreen frequently.
• Opt for cosmetics and makeup with an SPF. 
• The sun should be avoided between 10 am and 3 pm.
• Don't let the sun overheat your skin by seeking shade or spritzing your skin with cold water.

When to see a dermatologist?

A Dermoscopy examination can help to clarify the diagnosis. A skin biopsy for histological evaluation may be carried out if there is still diagnostic uncertainty. In order to distinguish apparent sun spots from much more serious illnesses like skin cancer, it is crucial to have them evaluated.

Cryotherapy or Freezing: Using a cotton-tipped swab and liquid nitrogen for no more than five seconds, this method treats the area. The excess pigment gets destroyed in this way. The skin appears lighter as the wound recovers. One or a few places can be frozen using a spray. The procedure carries a small risk of producing temporary skin irritation as well as permanent scarring or discoloration.

Dermabrasion and Microdermabrasion: A rapidly moving brush is used in dermabrasion to sand down the skin's top layer. In its place, fresh skin develops. The procedure might need to be done more than once. Temporary redness, scabbing, and swelling are potential adverse effects. Pinkness may take several months to go away.

Using a special tool with an abrasive tip, microdermabrasion entails gently exfoliating the topmost layer of your skin, and the dead skin is then suctioned off. It takes around an hour, is relatively painless, and doesn't call for anesthesia. Following the procedure, your skin will feel tight and pink, but this will pass quickly.
