Over half of women learn how menopause affects their skin only after it happens to them. 💛
Dryness, thinning, loss of firmness, new breakouts, redness: as estrogen declines, skin can change faster than many of us expect. Too often, no one mentions it until we’re already in it.

This , we’d like to change that. Whether you’re in your 30s, in perimenopause, or well past menopause, it’s never too early (or too late) to talk with a dermatologist about what’s ahead and how to care for your skin through every stage.

Most people living with eczema have never been officially diagnosed. 👀
About 1 in 10 Americans has eczema, but a new report from the National Eczema Association found that only 1 in 5 of those likely affected have received a diagnosis. That leaves millions managing flares on their own, guessing at products, and assuming it’s just how their skin is.
If you’re dealing with itchy, dry, or inflamed patches that keep coming back, especially as the weather cools, it may be more than sensitive skin. Our team can help you figure out what’s really going on and build a plan that works for you.
This , give your skin a real answer.

He's watching. And honestly? So are we. 👀🎃
Consider this your friendly (slightly creepy) reminder from your derm team:
☀️ SPF doesn't take the fall off. UV rays are still strong in October.
🔥 Heat can make melasma worse, so hot yoga and saunas count.
🧢 A wide-brimmed hat is the easiest sun protection there is.
💉 Skip the gym for 24 hours after Botox.
Which one got you? Confess below 👇

Consider this your Sunday night skin check-in. 🌙
Wash off the weekend, moisturize, change that pillowcase you’ve been meaning to change, and take a second to actually look at your skin.
Notice a spot that’s new, changing, itching, bleeding, or just doesn’t look quite right? Don’t wait for your next Sunday reset to think about it. Schedule an appointment with us this week. 🤍
Here’s to starting the week with healthy skin.

The holiday countdown is officially ON. 🎃🦃🎄🥂
If you’ve been thinking about refreshing your look before the holiday season, now is the time to start planning, because your aesthetic treatments deserve a little more notice than your last-minute holiday shopping. 😉
💉 Neurotoxins: Botox, Dysport and other neuromodulators begin working within days, with full results generally assessed around the 2-week mark. Give yourself time before your event for results to fully develop.
✨ Filler: Many fillers provide an immediate visible change, but swelling and bruising can happen after treatment. Planning ahead gives everything time to settle before photos, parties and celebrations.
⚡ Lasers + skin treatments: Depending on the treatment and your goals, you may need downtime, multiple sessions or several weeks to see your best results. Collagen-building treatments can continue improving skin over time, which makes starting early even more important.
Don’t wait until the week before your holiday party to get on the books. Start the conversation with your provider now so you can create a treatment timeline around your plans, your skin and the results you want. ✨

The sun might be aging your skin more than your birthday is. ☀️👀

Up to 80% of visible facial aging has been attributed to UV exposure, meaning many of the changes we associate with getting older, including fine lines, wrinkles, uneven pigmentation and changes in skin texture, can also be signs of cumulative sun damage.

The good news is that UV exposure is one of the most preventable contributors to premature skin aging.

Your daily non-negotiable: broad-spectrum SPF 30+, even when it’s cloudy, cool or you’re spending most of the day indoors. And if you’re already seeing signs of sun damage, your dermatologist can help create a treatment and skincare plan tailored to your skin.

Protect the skin you’re in today and the skin you’ll have years from now. 🤍

First day of fall = time for a little skin reset. 🍂
After a summer of sun, heat and long days outdoors, your skin may be ready for a seasonal check-in. Take stock of new or changing spots, address lingering sun damage, bring hydration back to your barrier and make a plan for the concerns you’ve been putting off.
And one thing that doesn’t change with the seasons? Your SPF. ☀️
Consider this your fall reminder to check in with your skin—and your dermatologist. Save this checklist for your next appointment.

Fall season is here, and it isn't just about layering up your wardrobe — your skin needs a layer-up too. 🍂 As humidity drops, so does skin's ability to hold onto moisture. It can leave your skin feeling tighter, drier, and more reactive than it was just weeks ago. It's not your imagination — it's chemistry.
What's the first sign you notice when your skin starts feeling the seasonal switch? 👇
Be sure to schedule an appointment, and the next time you're in, don't be shy about sharing any changes you've been experiencing.

Your skin can give away more than your age. 👀
Skin quality- its firmness, texture, tone and overall appearance - is one of the visual cues we associate with health and vitality. And because changes in collagen begin earlier than many people realize, taking care of your skin isn’t something that needs to start only once wrinkles appear.
That’s why we think beyond treating individual lines. A personalized aesthetic plan can address the quality of the skin itself while evolving with you through every decade.

The goal is to take care of the skin you’re in today so it continues to look and feel like your skin for years to come. ✨
Give us a call to get on the books and start building your personalized skin journey.
