Laser/Fraxel for Skin Treatment. How Would Laser Burning Rejuvenate Your Skin?

I have often read "rather than damaging your skin's ability to look young, Fraxel helps photorejuvenate your skin's texture." Now, if sun exposure damages skin how would laser burning your skin rejuvenate it? Then wouldn't sun also rejuvenate the skin, especially if sun exposure is slower and milder than laser.

Fraxel and photorejuvenation

Sun ultraviolet radiation penetrates into the skin and causes abnormal changes to cells' DNA which leads to abnormal skin cells and possibly skin cancer.  Uv radiation causes thinning of the skin.

Fraxel laser energy is fractionated which means that tiny little beams of light penetrate into the skin.  It is not ultraviolet light so it does not cause abnormal damage to DNA.  The heat of the laser stimulates new collagen, old skin cells near the surface of the skin, including brown pigmentation, are sloughed off, and the skin is smoother and fresher.  Meanwhile, new collagen continues to form and thickens the skin.

The success of laser treatments lies in the experience of the provider.

I am not always a big believer in the Fraxel.  However, as a Diplomate of the American Board of Laser Surgery (ABLS) and of the American Board of Cosmetic Surgery (ABCS), who has many years of experience with lots of different lasers; there are laser/light-based treatments that do work extremely well (if properly matched for each individual patient).  Please consult a Facial Cosmetic Surgeon who is Fellowship Trained (especially in lasers).

How does fractional laser treatment rejuvenate the skin

The idea is that if you wound the skin, it responds by healing and depositing collagen in the area of the wound.  The problem is when the wound is large, it forms a visible scar.

Fractional laser resurfacing creates thousands of tiny “wells” through the top layers of skin, causing immediate contraction of existing collagen around the "wound" and formation of new collagen in the deeper layers of the skin. Because entire layers of skin are not removed, healing occurs quickly.

Fraxel is effective for facial skin rejuvenation

Fraxel is very effective for facial skin rejuvenation. The difference is that UVA and UVB radiation (sun and tanning beds) damage the skin by damaging the DNA in the skin cells. Fraxel and other lasers transmit laser energy to the skin. In some cases this can ablate (vaporize) the skin causing a wound that is repaired with "new" skin. Lasers can also heat the surrounding skin causing a thermal injury. These two aspects of laser treatments result in new collagen synthesis and this is responsible for the rejuvenation of the facial skin surface. Contemporary lasers are safe and highly effective but seek out an experienced cosmetic surgeon to perform these treatments.
