What should you know about knee stretch marks?

Stretch marks form when the skin changes faster than its supporting tissues can adapt. Growth, changes in body size, muscle development, pregnancy, or medicines that affect the skin can contribute. Around the knees, bending and repeated movement can make lines easier to notice. Early marks may look pink, red, purple, or darker than nearby skin; older marks often become lighter and slightly indented. They are not contagious and are not a sign of poor hygiene.

Use a gentle moisturiser to reduce dryness and friction, and apply broad-spectrum sunscreen to exposed knees because tanning can increase contrast between the marks and surrounding skin. Avoid vigorous scratching or unregulated creams marketed as a guaranteed cure. A dermatologist can assess the colour, texture, and age of the marks before discussing options such as Microneedling, Fractional Laser Treatment, RF Microneedling, or Carboxytherapy. These procedures may require more than one visit and are selected according to skin tone, healing history, and the type of mark.

Arrange a medical assessment if the marks appeared suddenly without an obvious change in growth or body size, spread quickly, become painful, bleed, or occur with easy bruising, marked weakness, or other new symptoms. Seek advice before treatment if you are pregnant, breastfeeding, using steroid tablets or creams, or have a history of raised scars. Prompt review can distinguish ordinary stretch marks from a skin change needing different care.

Ask what type and stage of stretch mark you have, whether a procedure suits your skin tone, what improvement is realistic, how many appointments may be needed, and which aftercare products or sun precautions matter most.
