Investigators in Australia and Austria have discovered a particular DNA enzyme in the skin of kangaroos that is effective in repairing the genetic damage associated with many skin cancers. This same enzyme is also present in other animals but not in humans. Sunscreens can be helpful in blocking the skin’s absorption of the damaging rays of the sun but it is unpredictably effective and doesn’t treat damage already sustained.

Sunlight with its various wavelengths of ultraviolet light, particularly UVA and UVB, has been associated with aging of the skin including loss of elasticity, pigmentation irregularities and wrinkles as well as skin cancers such as basal and squamous cell carcinomas and the dreaded malignant melanoma. If a topical agent such as a cream or lotion can be manufactured that could repair DNA damaged by ultraviolet light exposure, this would be an incredible breakthrough and an extremely effective way to lower one’s risk of developing skin cancers.

Still, prevention is key. It is important to minimize the exposure of your unprotected skin to strong sunlight as well as avoid tanning booths. This will reduce your future risk of developing skin cancers as well as help keep your skin looking more youthful longer.

If you have any questions about rejuvenative skin care products or procedures such as the CO2 Laser or chemical peels, sunscreens or any cosmetic procedure that I perform or you would like to schedule a complimentary consultation, please contact my office at 480-451-3000.
