Happy National Dermatologist Day!

Today we celebrate the physicians who dedicate their expertise to the health of our skin. Dermatologists do far more than treat conditions, they help detect skin cancer early, manage chronic skin diseases, guide patients through complex skin concerns, and support people at every stage of their skin journey.

We’re proud to work alongside board-certified dermatologists who combine science, skill, and compassion to help patients feel confident and cared for in their skin.

If it’s been a while since your last skin exam, consider scheduling a visit with a board-certified dermatologist. Your skin is your body’s largest organ, and it deserves expert care.

If your friendly feline played a little too hard, this one’s for you. Cat scratches may look minor, but they can introduce bacteria into the skin, especially if the surface is broken. Acting quickly can help reduce the risk of infection and scarring.
Most cat scratches heal without issue when treated early. Clean the area promptly, protect the skin barrier, and don’t ignore changes, your skin will let you know when it needs extra support.

Thinner skin means fewer collagen and elastin reserves, which is why laxity and creasing show up sooner in the neck compared to the face.

Up to 60–70% of adults report visible neck lines they associate with device use.
And it makes sense: repetitive downward flexion from looking at screens accelerates horizontal neck creases much earlier in life.
