A strong sunlight selfie to illustrate the Very High UV index today in Burlingame. But the UV Index isn’t just how sunny it is- it’s is scientific measure of how intense the sun’s ultraviolet radiation is at the Earth’s surface at a given place and time. It mainly reflects UVB rays (which cause sunburn) but also accounts for UVA exposure (which contributes to aging and skin cancer).

The scale ranges from 0–11+:
0–2 = low
3–5 = moderate
6–7 = high
8–10 = very high
11+ = extreme

At a UV Index of 8, unprotected skin can begin to burn surprisingly quickly — often within 15–25 minutes depending on skin type. For someone fair like me, the 15 minute building evacuation we had today could have been a burn waiting to happen! But I wear sunscreen every day, and sought shade right after I snapped this pic.

UV levels are influenced by:
☀️ Time of day (highest midday)
☀️ Season
☀️ Altitude
☀️ Cloud cover
☀️ Reflection from water, sand, and concrete
☀️ Ozone levels in the atmosphere
And importantly: temperature does not determine UV intensity. Cool or breezy days can still have dangerously high UV exposure.
Daily sunscreen, protective clothing, hats, sunglasses, and shade are all part of reducing cumulative UV damage over time.

UV Index forecast is high all weeks so stay ready!

I got a few questions about this Story so I thought I’d dive deeper… Many patients with atrophic acne scars have uneven, rolling skin texture punctuated by deeper boxcar or ice pick scars. Sculptra, or poly-L-lactic acid, is a biostimulator that is injected into the deep dermis to increase collagen production for skin smoothness and firmness. Skinvive, or microdroplet hyaluronic acid, is injected into the superficial dermis to draw water, plumping and hydrating the skin. Together they provide a synergistic boost to skin quality and elasticity, improving the look of the acne scars.

This is just one pair of tools in my acne scar toolbox- my patients receive personalized recommendations for their acne scars. Come in and see what we can do for you!

Oh, melasma. It takes a village to improve those stubborn gray-brown patches of deep pigmentation in the skin. I spend time teaching my patients to avoid triggers, how to use topical and oral medications safely, when and what lasers to use. It’s a journey- I’m here with you for it!

The dentists and Mohs surgeons know it- redheads can require more anesthetic to get numb than the rest of them!

One last pearl from the .college conference: the biggest take home for me is the insight that sharing vulnerability creates trust. Whether it’s admitting to patient that I’m not sure what the best option is, or admitting to my team that I didn’t perform my best, or admitting to myself that I have more to learn, it’s so important to be honest and open. I am continually learning and striving to be a better dermatologic surgeon, and I am humbled by how much better I get every day.
