This office is wonderful! Dermatologists are notoriously difficult to get in to timely, St. Louis Dermatology in Troy is so easy to get an appointment at (the “longest” I’ve waited is a week for a non-urgent appointment). Kayleigh is an excellent provider, remembers your previous visits and concerns, and doesn’t rush through the appointments. The in office procedures they offer as well are very convenient and often saves you on your out of pocket costs with insurance when the in office procedures are billed with your office visit. So grateful to have such a great local derm!
Response from the owner:Thank you so much for leaving us a stellar review!

I absolutely love this office. They handled my surgery with exceptional care, and I can finally say I’ve found the right team. I drive 55 minutes for every appointment because Dr. Beal and his staff are truly outstanding. Their professionalism, compassion, and commitment to patient care make the trip more than worth it. I always feel supported and confident that I’m receiving the best possible care. Highly recommend!

What Are Age Spots?

Age spots, also known as liver spots or solar lentigines, are flat, brown or gray patches that typically appear on sun-exposed areas of the skin as we age, especially after the age of 40.

Key Characteristics:

  • Flat, round, or oval patches
  • Light to dark brown
  • Common on hands, face, shoulders, and chest
  • Result from years of UV exposure
  • More common in fair-skinned individuals

Age spots are not dangerous but can be a cosmetic concern for many patients. While harmless, it’s still important to get new or changing spots checked by a dermatologist.

What Are Sun Spots?

Sun spots are a type of hyperpigmentation caused by UV radiation. While similar in appearance to age spots, sun spots can occur in younger individuals, especially those with prolonged sun exposure without protection.

Differences from Age Spots:

  • Appear sooner, sometimes in your 20s or 30s
  • Often lighter or more diffuse in appearance
  • Typically fades slightly over time with sun avoidance
  • Can develop after sunburns or tanning

Think of sun spots as the early warning signs of UV damage — and a cue to ramp up your SPF game.

How to Tell the Difference: Age Spots vs. Sun Spots

FeatureAge SpotsSun Spots
Age Group40+All ages (especially 20s–40s)
CauseCumulative sun exposure + agingRecent or repeated sun exposure
ColorDark brown, well-definedLight brown, less defined
TextureFlat and smoothFlat and smooth
LocationHands, face, chest, shouldersSame areas, sometimes more diffuse
RiskCosmeticCosmetic, potential for long-term damage

Important Note: If a dark spot changes shape, bleeds, or becomes raised, it could be more than just an age or sun spot — get it checked by a board-certified dermatologist.

Should I Be Concerned About These Spots?

While age spots and sun spots are typically benign, they can sometimes be confused with:

That’s why we recommend an annual skin exam at SLD — especially if you’ve had significant sun exposure or a family history of skin cancer.
