Doctors use lasers and retinoic acid to treat skin damage. In this article, we will see how scientists have now uncovered a common mechanism that links both, paving the way for new treatments.

Aging shows on our skin

Skin damage, in the form of dark spots and wrinkles, naturally occurs as we age. Ultraviolet light from the sun is a major factor in skin aging and causes what experts call photoaging. Cosmetic procedures, such as laser treatment, chemical peels, and microdermabrasion, can reduce some of the signs doctors associate with photoaging.

Indeed, experts predict that the facial rejuvenation industry will increase its market revenue from just over $17 billion per year in 2018 to around $25 billion in 2025. Yet our knowledge of how the techniques that dermatologists and plastic surgeons traditionally use on our skin work is still in its infancy.

A derivative plays a central role in embryonic development, and scientists know that it contributes to skin and limb regeneration in animal models.

Researchers from the Department of Dermatology at Johns Hopkins University School of Medicine in Baltimore, MD, along with national and international collaborators, are seeking to further our understanding of the molecular processes underpinning skin rejuvenation technologies.

In a recent publication in the journal Nature Communications, they present their latest findings and explain how this may lead to better treatments in the long run.
