Treating tinea versicolor is not a tedious task. Using antifungal products to prevent fungal growth is an effective remedy.

Sunspots, also known as guttate hypomelanosis are the white spots on the skin, which happen due to exposure to the sun.  These white spots on skin from the sun are harmless and are frequent in people over the age of 40. These white spots on the skin are not suggestive of skin cancer and happen when skin loses melanin. There are no symptoms related to white spots from the sun and tend to appear first on legs and then progress towards the rest of the body. 
The key to avoid sunspots is cutting off sun exposure. Before you step out of your house, do not forget to apply sunscreen over the exposed body parts. Topical steroid and retinoid creams help to remove the outer skin layer proving themselves efficacious. 
Melanocytes are the cells present in our skin responsible for making melanin, a skin pigment. Vitiligo is an autoimmune condition in which the body attacks the melanocytes and renders white patches on the skin.  Vitiligo may also be a result of the genetics of a person. It appears in a person’s twenties. Emotional stress and physical illness are also among the causes of white spots.

- Vitiligo also develops in areas exposed to the sun.
- Common areas include armpits, groin, genitals, nostrils and eyes.
- Premature greying of hair.
Corticosteroid creams are an effective measure. Decolouring the surrounded skin to blend with the affected area. Ultraviolet therapy, surgical treatments to remove the discoloured skin layer in case other medications are not effective.  Certain cosmetic products are helpful in hiding the white spots on the skin.
Milia are raised, white bumps on the skin. Our face contains keratin which when trapped under the skin causes milia.  It is a self-curable condition. It is most common in new-born babies.

Symptoms of milia include
- Sacs filled with fluid on skin,
- Small white spots around eyes, nose and forehead,
- Fat build up in immune cells of the body. 
Milia disappears itself with time. However, if they are persistent then the following options are prescribed. Using retinoid creams to remove milia.  Exfoliating facial peels may too prove helpful in getting rid of white spots.  But the facial peel should not be a strong one, as this may cause excessive milia to occur instead of curing it. Use mild soaps for cleansing the face.
Which Vitamin Deficiency Causes White Spots on Skin?
White spots on our body are indicative of adding vitamin B12 in our diet. A lack of vitamin B12 causes a loss in melatonin in our bodies leading to white spots.  Deficiency of vitamin D and vitamin E also lead to white spots.  Therefore, these spots are a sign of building a healthy diet plan rich in these vitamins.
Can White Spots on Skin be Skin Cancer?
Skin cancer is a very common type of cancer. Skin cancer symptoms include reddish, scaly patches on the body.  These patches may have an itching sensation and sometimes bleed.

These tell us about an unhealthy and unbalanced diet.
White spots disappear on their own, but if they bother you then consulting a doctor is a good option. Many of the treatment creams prescribed are easily available online. Other treatments such as UV light treatment are also a harmless and effective treatment against the white spots. However, they may take sufficiently long to show results, therefore, being patient is the key to such treatments.
