Any injury to the body whether by accident, trauma or surgery, heals by wound healing mechanism. During this repair mechanism the injury site is filled by raw collagen and fibrotic tissue and is called a scar. Some scars heal well and lighten on their own over the years. However, in some patients, due to altered wound healing mechanism, the scars become bigger in size, known as hypertrophic scars or turn into keloids which is blackish brownish thickened growth at the site of scar. Some scars remain depressed due to loss of tissue during the trauma or inflammation, eg Acne scars, stretch marks. While scars cannot be removed completely, most of them can be made to merge with the surrounding skin to make their appearance better and make them almost unnoticeable. This can be achieved with technologies like micro-needling radiofrequency, fractional CO2 laser, Erbium YAG laser etc.
Different techniques and lasers are chosen depending on the size, colour, thickness of the scar. When a laser shot is given at the site of scar, it produces multiple micro traumas without damaging surrounding healthy skin. This leads to the proliferation of fibroblasts and new collagen formation which replaces the bad collagen and fibrous tissue created by the previous scars over next 3-4 weeks. This makes the scar tissue soft, elastic and there is improvement in colour of the scar, reduction in the size of the scars.
Laser scar treatment is done under topical or local anaesthesia, once in 4-8 weeks for 4-6 times to achieve best results. Mild redness may be present after the session which usually vanishes after a few hours or 1-2 days maximum. Adequate sun protection is advised post laser scar treatment to avoid chances of developing pigmentation in the treated area.
Keloids are scars that grow beyond the original borders of the wound. They are raised, often dark in colour and hard to the touch. They can be painful, itchy, unsightly and may continue to grow if left untreated.
Until recently keloids were considered difficult to treat and patients had to bear them lifelong. But with recent advances, keloid treatment has proved to effective in relieving symptoms such as pain, itching, stretching sensation and making them flat.
It’s important to control the trigger factors of keloids for best improvement in their size.
