Acne is by far the most common skin disorder that people seek treatment for.

Dehydrated skin occurs when the protective uppermost layer of the skin is lacking in moisture.

Skin ageing is characterised by features such as wrinkling, loss of elasticity and rough-textured appearance.

Rosacea is a common skin condition that causes redness and visible blood vessels in your face.

Skin pigmentation disorders affect the colour of your skin.

Also known as desquamation, scaling skin occurs when the epidermis (outer layer of the skin) begins to flake off, creating a rough texture.

Sagging skin is a cosmetic "condition" that occurs naturally in many people as they age. The skin loses its youthful appearance as it loses elasticity and volume over time, which causes it to droop, resulting in jowls and eye bags.

Wrinkles around the lip and mouth are referred to as expression lines. While environmental free radicals, age, loss of collagen and genetics could contribute to their existence, expression lines are also simply the result of repetitive facial expressions over years that reduce the skin's elasticity and crease the skin.

Dark circles under your eyes happen when the skin beneath both eyes appears darkened.

Dry type facial skin is facial skin that has a tendency to be dry and typically feels tight and slightly very rough in some areas.

A double chin, also known as submental fat, is a common condition that occurs when a layer of fat forms below your chin. A double chin is often associated with weight gain, but you don't have to be overweight to have one. Genetics or looser skin resulting from ageing may also cause a double chin.
