How Lasers and Microneedling Can Heal Your Scars

Scars are seen as a permanent affliction that marks and discolours the skin. There are several treatment options available to help fade or remove scars entirely. However, since there are various types of scars, and there are also several different treatments, people commonly wonder which scar treatment is right for them.

What Causes Scars?

Scars have several causes including but not limited to acne, injury, surgery, or burns.  Whatever the reason, scars are usually unwelcome and unwanted.

Scars form during the skin’s natural healing process after an injury. The cells from the dermis begin to repair the damage by producing extra collagen (a structural protein) to close the wound. The healing process can be very aggressive and when this happens the body produces too much collagen, resulting in a raised and lumpy scar. Alternatively, there are times when too little collagen is produced and this creates an indented or pitted scar.

Scar treatment is influenced by the type and texture of the scar. There are keloid or raised scars, and atrophic scars which are indented. Hypertrophic scars are also raised but not to the level of keloid scars.

Laser Treatment for Scars

Thanks to the evolution of laser technology over the last few years, lasers can now be effectively used to erase or fade many types of scars.

Laser skin resurfacing is a process that uses laser energy to remove the scarred skin. Lasers also have a tightening effect on the skin because they stimulate collagen production.

There are several types of lasers commonly used for laser skin resurfacing including pulsed dye lasers and fractional lasers.

Scar Treatment With Pulsed Dye Lasers

Pulsed dye lasers emit an intense beam of high-energy laser light that selectively targets the scar. The energy is absorbed by the pigmentation in the scar, heats up, and then removes the excess tissue. Pulsed dye lasers are often used to treat hypertrophic and keloid scars.

Pulsed dye laser treatment is safe and virtually painless. After treatment patients can expect mild swelling and slight redness, much like a sunburn.

The Vbeam Perfecta by Syneron Candela is one of the most advanced pulsed dye lasers on the market, and is widely used to treat scars and other skin conditions.

Scar Treatment With Fractional Lasers

Fractional lasers emit tiny beams of light that create hundreds of microscopic holes in the skin. These microscopic treatment zones are surrounded by healthy skin that quickly starts the repair mechanism. Over time the dead skin cells are broken down and new, fresh skin cells are produced.

Healing also activates collagen formation, this helps to improve the appearance of the scar in the long term. Atrophic and hypertrophic scars respond well to fractional laser treatment after about 6 sessions.

Scar Treatment With Microneedling

Microneedling is a cosmetic treatment in which very tiny needles are used to penetrate the skin and break down old scar tissue. The creation of these micro-wounds jumpstarts the skin’s repairing process. This stimulates the production of more collagen and elastin. As the skin regenerates, new skin cells are produced, and this improves the overall appearance of the skin making it firmer, clearer and smoother.

Microneedling is commonly used to treat acne scars and surgical scars. It is safe for use on all skin types and skin tones. It typically requires 3 sessions spaced 4 weeks apart to achieve the expected results with microneedling.

In Conclusion

Whether it is with lasers, microneedling or a combination of the two, there are many effective treatment options available today for improving or removing scarring. If you are interested in any of these treatments you can contact a dermatologist near you here:
