| As the name suggests, birthmarks are marks that appear on the skin shortly after birth. They can be of different shapes, sizes, and colours, and can be located anywhere on the body. Most birthmarks are harmless and do not require treatment. However, some birthmarks can be a sign of an underlying medical condition and require further evaluation. If a birthmark is causing cosmetic concerns or affecting a person's quality of life, it can be removed through laser therapy or surgical excision.

| Moles are common skin growths that can appear anywhere on the body. They are usually brown or black in colour, and can be flat or raised. Moles are caused by the accumulation of pigment cells, and most of them are harmless. However, some moles can be a sign of skin cancer, especially if they are irregular in shape, have uneven colour, or have changed in size or shape. If a mole is causing concern, it can be removed through laser therapy, excision, or cryotherapy.

| Warts are caused by the human papillomavirus (HPV) and are a common skin infection. They can appear anywhere on the body, but are most common on the fingers, hands, and feet. Warts are usually harmless and can disappear on their own over time. However, some warts can be painful, unsightly, or affect a person's quality of life. They can be treated through cryotherapy, laser therapy, or topical medications.

|
| Xanthelasma is a yellowish deposit of cholesterol under the skin, usually on the eyelids. It is a sign of high cholesterol levels and can be a risk factor for heart disease. Xanthelasma is usually harmless and does not require treatment. However, if it is causing cosmetic concerns, it can be removed through laser therapy or surgical excision.

| If you have a wart, try to avoid touching it, as this can help prevent the spread of the virus to other areas of your body or to other people.
