Corns and calluses are areas of stumpy skin caused by friction or pressure. They usually hurt when you wear shoes or walk.

Calluses generally develop on your feet or hands, and most of the time, don’t require treatment.

Corns have a hard or soft inner core. Soft corns are mostly found between the toes, while hard corns form on the top of the toes. Corns that are caused by ill-fitting shoes often reduce on wearing the right shoes.

Causes

Repeated friction or pressure causes corns and calluses on areas of skin. The pressure leads to the death of the skin, which develops a protective, hard surface. Soft corns develop in a similar fashion. Corns and calluses are not formed due to viruses and are not harmful. They can be formed due to:

1. Regular usage of any object that puts strain on the hands, such as sports equipment (badminton racquet) or tools (hammer or gardening hoe), usually leads to calluses on the hands.

2. Pressure from wearing the wrong footwear usually leads to corns and calluses on the feet. Calluses can also form by walking barefoot.

3. Abnormal structures on the foot, such as hammertoe or bone spurs, can cause calluses and corns.

4. Repeated pressure from playing certain sports can also cause calluses on the feet.

Symptoms

Corns and calluses on the feet are easy to spot. A callus is thick, hard and dry, and may appear yellowish or grey in colour. When touched, it will feel bumpy and more insensitive than the skin around it. A hard corn is thick and firm, while soft corns look like an exposed sore. The hard corn may have a grey centre with a light yellow ring around it.

Corns and calluses don’t hurt, but it does become painful when you are wearing shoes or walking. Fitting your feet into shoes gets more difficult due to them. Touching or squeezing the corn or callus can also be painful.

Treatment

Corns and calluses don’t require treatment normally, but if they hurt, here’s what you can do:

1. Wearing well-fitting shoes that are roomy with deep and wide toe boxes (the area covering the toe).

2. Protective paddings, such as moleskin, toe separator, toe sleeves, etc., can alleviate pain.

3. Soaking the corn or callus in hot water, and then gently wear down the dead skin by using a pumice stone.

4. Salicylic acid can be used to soften the corn or callus.

Melasma is a common skin problem where the skin becomes patchy brown, tan, or there is blue grey facial skin discoloration. It is also known as chloasma or mask of pregnancy. It occurs in women during the reproductive years and occurs rarely in men. It is primarily related to external sun exposure, external hormones like birth control pills and internal hormonal changes seen during pregnancy. Women with Melasma have a history of daily or intermittent sun exposure.

• Symptoms of Melasma: Melasma causes patches of discoloration, which are darker than typical skin colour. It occurs symmetrically with matching marks on both sides of face. It normally appears on the upper cheeks, upper lip, forehead and chin. It can also occur on the other areas of one's body which are often exposed to sun. Skin discoloration is not physically harmful, but it can affect the self-confidence of a person. Darker skinned individuals are more at risk as compared to fair skinned individuals. Melasma is associated with oestrogen and progesterone sensitivity, thus it can be triggered by birth control pills, pregnancy and hormone therapy. In few cases, stress and thyroid disease can also cause Melasma. Women taking hormone replacement therapy during menopause are also at high risk of getting Melasma
• Diagnosis of Melasma: A visual exam of the affected area is sufficient to diagnose Melasma. The doctor will perform the wood's lamp examination that uses ultraviolet (UV) light to look at the skin closely. However, the doctor may perform a biopsy to check for any serious skin conditions.
• Treatment of Melasma: When Melasma is caused by pregnancy or birth control pills, it disappears on its own. One can use creams containing hydroquinone or prescribed topical steroids, which can lighten the tone of the affected areas. Other options include chemical peels, dermabrasion and microdermabrasion which will remove the upper layers of skin and help lighten dark patches. In cases of severe Melasma, doctor may suggest laser treatments to remove the dark pigment.

It is quite possible that Melasma will clear up with treatment, there are things one must do to not to aggravate the condition and minimize appearance of the discoloration. These include usage of makeup to cover areas of discoloration, wearing sunscreen daily or wearing a hat with wide brim to provide shade to the face. The patients with Melasma are known to be at a lesser risk for Melanoma. Even if Melasma disappears, it can strike back especially if preventive measures regarding exposure to sun are not followed. Resolution with strict sun avoidance and topical bleaching creams can take sufficient time and patients should expect slow, but gradual lightening.
