What are white spots on skin?
White spots on skin also known as hypopigmentation occurs when the skin loses melanin, the pigment responsible for skin colour. It can also occur when dead skin cells become trapped. These spots may appear anywhere in the body and may range from smaller to bigger patches. While these spots are generally harmless, they can sometimes signal an underlying health condition.
Some people might describe it as “white patches”, “dry white spots on the skin” or even “tiny white dots” depending on the appearance. Treatment varies entirely depending on the root cause.
Common causes of white spots on skin
White spots on skin can appear due to various reasons ranging from sun damage to chronic skin diseases & allergies. Common causes of white spots include:
Sun damage and white sunspots on skin
Idiopathic Guttate Hypomelanosis also known as white sunspots on skin are small, flat white spots caused by prolonged sun exposure. These spots usually cause no symptoms and appear first on the area exposed by sun such as arms, shins and upper chest.
Symptoms: Tiny, round, white spots on sun exposed skin
Treatment: Sunspots can be prevented through daily sunscreen use. Improvements can be seen with laser therapy or cryotherapy.
Tinea versicolor
Tinea versicolor is a fungal infection, caused by the outgrowth of yeast that naturally lives on the skin. It is a common condition in teens and young adults. This usually forms in the middle of the body or the shoulders. The fungus causes dry, flaky patches that are either dark or lighter than the surrounding skin and are itchy as well.
Symptoms: White, small, scaly or discoloured patches often on the chest, back and shoulders
Treatment: Antifungal creams, shampoos or oral medications prescribed by the healthcare provider.
Pityriasis alba
Pityriasis is a common, non-cancerous childhood condition that causes raised, round or oval patches on the face. These patches can be up to an inch in size. It can be a mild form of eczema in children. These patches eventually fade away and leave behind small spots that usually go away over time.
Symptoms: Round, raised or oval patches in children on the face or upper body
Treatment: Moisturizers and mild steroid creams like Tretin 0.025% Cream can be used to improve the appearance of the spots.
Vitiligo
Vitiligo is a skin condition where the immune system attacks the melanocytes leading to the loss of skin pigmentation. Melanocytes are the skin cells that produce melanin, pigments that produce skin pigments. It is an autoimmune condition. Areas of your skin that lose the pigment are called macules if they are less than 1 cm wide and patches if they are more than 1 cm wide.
It affects all the races and sexes equally. For many individuals, dealing with skin diseases & allergies pigment disorders become just as much an emotional concern as a physical one.
Symptoms: Large, irregular white patches on the skin that may spread
Treatment: While there is no cure, treatments such as topical steroids, non-steroidal creams, phototherapy or skin grafts may restore pigmentation.
Milia
Milia is a skin condition that causes small white bumps on the skin. About 40 to 50% of newborns in America have milia. Milia are harmless and only affect your appearance. Milia aren’t a type of acne. Primary milia occurs randomly when keratin gets trapped under the skin and forms a sac. Secondary milia occurs due to trauma from events such as tissue damage, blistering and skin inflammation.
Symptoms: White to yellow bumps
Treatment: Treatments such as adapalene gel or tretinoin cream like Tretin 0.025% cream, surgical procedures and cryotherapy.
Questions people almost ask immediately
Few of the questions people ask almost immediately after they know about the skin diseases & allergies are:
1) Are white spots on skin contagious?
Usually no. Conditions like vitiligo, post-inflammatory hypopigmentation and pigment diseases do not spread from person to person. The white patches aren’t automatically contagious just because they’re visible.
2) Can white patches on skin spread?
White patches on the skin can spread, but they depend entirely on the underlying cause. Vitiligo can expand in some individuals. Fungal infections can involve larger areas if untreated. Post inflammatory pigment changes often stay limited to the original affected region only.
3) Can white spots on skin go away on their own?
White spots on the skin are usually harmless and resolve on their own. But conditions like Vitiligo do not resolve and may require specialized treatments.
4) Can stress cause white spots on the skin?
In most of the cases, stress doesn’t cause white spots on itself. Stress can flare-up or worsen the skin conditions. Many people living with skin diseases & allergies notice that most of the symptoms are seen during stressful events. Periods of emotional stress sometimes seem to coincide with skin changes, though that doesn’t mean stress alone created them.
