Most people only start thinking about their skin when something looks wrong. But by the time you notice dullness, sagging, or fine lines, the underlying changes have usually been building for years, under the surface, unnoticed and unsupported.

In the past decade, the number of new invasive melanoma cases diagnosed annually has increased by 46.6%. This year alone, an estimated 65,000 cases will be diagnosed in men and 46,000 in women.
As we recognize Skin Cancer Awareness Month, it’s important to remember that melanoma remains the deadliest form of skin cancer. Awareness matters — not only when it comes to changes on your own skin, but also noticing something new, changing, or unusual on the people you love.
Don’t be afraid to speak up if you notice something that looks concerning. A simple conversation could make a life-changing difference.
Take this month as a reminder to schedule your annual skin check with your dermatologist. Early detection saves lives.

Your skin goes through a lot, daily exposure to pollution, stress, sun, and natural hormonal changes over time.
Laser treatments can be a powerful tool to help support skin health, improving tone, texture, and overall radiance. For many patients, incorporating a treatment every ~6 months, similar to a routine dental cleaning, can help maintain long-term results.
Call us to schedule your consultation and find the right plan for your skin.

False. This is about technique... not the product.
Overdone Botox = frozen.
Well-done Botox = expressive, just softened.
Botox has been used for decades in both medical and cosmetic settings, with a strong safety profile when performed by a trained provider. And no, it’s not permanent. Results typically last 3–4 months, with movement gradually returning over time. If you're interested in starting your tox journey, give us a call this week.

As estrogen declines during perimenopause and menopause, skin changes are not “just in your head.” They are biological, common, and often happen faster than many women expect.
You may notice:
• More dryness and dehydration
• Thinner, more fragile skin
• Fine lines and deeper wrinkles
• Loss of firmness and facial volume
• More redness, sensitivity, rosacea, or irritation
• Pigmentation, uneven tone, or melasma
• Even adult acne, as hormone levels shift
The good news is that with more research, we are better understanding what is happening during this phase of life, allowing us to support skin differently. The right skincare, treatments, and consistency can make a profound difference because your skin is changing and your skincare should too.
If you feel like your skin changed overnight, you are not imagining it and you are not alone. Give us a call.

Skin cancer doesn’t always show up where you expect it. It can appear in sneaky spots like your scalp, eyelids, ears, palms, and the soles of your feet. Sometimes, it can even develop in areas that don’t get sun exposure at all, like the groin or ge****ls.
That’s why early detection saves lives.
Take a few minutes to check your skin each month, paying attention to any new, changing, or unusual spots. And if it’s been a while since your last skin exam, give us a call this week so we can make sure you’re up to date on your annual skin check.

Vitamin C is best known for immune support but its impact on skin is just as important!
It plays a critical role in collagen production, helping stabilize and strengthen the fibers that keep skin firm and smooth. Without enough vitamin C, collagen can’t form properly.

In one population study of women, higher vitamin C intake was associated with ~11% less visible skin wrinkling, reinforcing its role in maintaining healthy, resilient skin.

When supported at the level of the skin, vitamin C can help improve brightness and overall radiance.
During your next visit, don’t hesitate to ask your provider which topical vitamin C options may be right for your skin.
