National Dermatologist Day is observed annually on March 13 in the United States, dedicated to board-certified dermatologists and their work in diagnosing and treating conditions of the skin, hair, and nails. The day also serves as a reminder of the importance of regular skin checks, sun safety, and early detection of skin cancer.

The observance was established in 2024 by EltaMD Skin Care, though similar observances on March 13 had already been recognized in Mexico since 2014 and the Philippines since 2015.

National Dermatologist Day — 4 Facts
Fact 01
Your skin is the body’s largest organ
Dermatologists often detect signs of internal diseases — including diabetes, heart disease, and thyroid conditions — through changes in skin texture, color, or new growths, sometimes before other symptoms appear.
Early warning system
Fact 02
Over 3,000 conditions treated
Beyond acne and skin cancer, dermatologists are trained to manage more than 3,000 diseases — including rare genetic disorders, autoimmune conditions, and problems affecting hair and nails.
3,000+ conditions
Fact 03
You shed roughly 40 pounds of skin in a lifetime
The average person loses 30,000 to 40,000 skin cells every minute. A significant portion of household dust is made up of these shed cells. Dermatologists help ensure this renewal process stays healthy.

Fact 04
Sun damage is permanent
Up to 80% of visible skin aging — wrinkles and dark spots — is caused by UV exposure accumulated over years. Dermatologists consider sunscreen the most effective anti-aging measure, regardless of skin tone or weather.

How to Mark the Day?

National Dermatologist Day is an opportunity to prioritize your skin health and show appreciation for dermatologists. Here are some meaningful ways to mark the day:

  • Schedule a head-to-toe skin screening with a board-certified dermatologist. Regular visits can catch potential issues early and keep your skin looking its best.
  • Revamp your skin care routine by incorporating dermatologist-approved products. Focus on essentials like a gentle cleanser, sunscreen, and a hydrating moisturizer.
  • It is also an opportunity to learn about common conditions such as melanoma, eczema, and psoriasis.
  • Use social media to share your appreciation for dermatologists and spread awareness about skin health. Post tips or thank your dermatologist using hashtags like #NationalDermatologistDay, #HealthySkinMatters or #ThankADerm.
