Comment “BOOSTER” and I’ll send you my simple comparison! 👩🏻‍⚕️✨

🔥 One of the hottest collagen boosters in Korea this Fall 2026? GOURI.

So what makes it different?

GOURI is a liquid PCL collagen stimulator.

Think of it almost like creating a temporary support structure—or scaffold—under your skin.

It stimulates your fibroblasts to build your own new collagen around the treated area.

Then, as the PCL gradually biodegrades, that newly formed collagen remains—helping your skin look firmer, smoother, and more supported over time.

Because GOURI is a liquid, particle-free formulation, it’s designed to spread evenly through the tissue with a lower risk of nodule formation.

Who is it for?

If you’re noticing thinner skin, fine lines, loss of elasticity, or early sagging, but you don’t necessarily want filler—this may be an option.

Typically, it’s done twice, about 4 weeks apart, with maintenance depending on your skin and response.

Want to know the difference between GOURI vs Rejuran vs RE2O?

🍊 Spending a lot of money on vitamin C serum? Make sure you’re applying it the right way!

Here’s how I apply mine 👩🏻‍⚕️

✨ Start with clean skin. I like to use a gentle toner pad to remove any residue and get my skin ready.

🍊 Vitamin C goes FIRST.
I use vitamin C + E + ferulic acid, then add a little extra vitamin C to areas where I have more pigmentation.

⏰ And here’s the important part: I don’t immediately layer my next serum.

L-ascorbic acid is pH-dependent. Research has shown that it needs to be formulated at a pH below 3.5 for effective skin pe*******on.

So I give my vitamin C about 5–7 minutes to fully absorb before moving on.

💆🏻‍♀️ And I don’t waste those 5–7 minutes! While I wait, I apply minoxidil to my scalp and dry my hair.

💧 Once the vitamin C is absorbed, THEN I apply my hyaluronic acid serum + moisturizer.

☀️ And of course—sunscreen every morning!

🍊 Vitamin C first.
⏰ Let it absorb.
💧 Then hydrate.

Small change, but a great way to get the most out of your vitamin C routine. 👩🏻‍⚕️✨

🇰🇷 My ONE fine-dining pick in Seoul

If you’re looking for a special dining experience in Seoul, add Soigné to your list. ⭐️⭐️스와니예 SOIGNÉ JunLee

What I loved most was the creative use of Korean ingredients, with dishes inspired by nature and the seasons.

Beautiful presentation, high-quality ingredients, wonderful protein dishes—and a dining experience that felt both modern and distinctly Korean.

As a well-aging physician, I’m always interested in how we can enjoy food not just for nutrition, but as an experience. And this was definitely one to remember. 🤍

Comment “THERMAGE” and I’ll share my general guide for how many shots and how often I typically recommend it by age.

We’re sister doctors👩🏻‍⚕️👩🏻‍⚕️—55 and 47—and we do a lot together.
We make YouTube videos together, create Reels together, practice medicine together… and one more thing we do together?

Our Thermage FLX. 🤍

Every year, without fail, we treat each other—and this summer was no exception.

Thermage FLX is one of our favorite well-aging procedures, and we personally do it about every 6 months to help maintain firmness and support collagen as our skin ages.

There are SO many radiofrequency and energy-based devices now, but Thermage remains our first choice because it has been around for years and is one of the most extensively studied non-invasive RF treatments for skin tightening, with a long track record of efficacy and safety.

It’s about maintenance.

We combine Thermage with other treatments when needed—for example, specific lasers or treatments targeting pigmentation, redness, melasma, acne, or overall skin quality.

So yes… even doctors treat each other. 😂
And Thermage is still the sisters’ first choice.

Of course, the ideal treatment plan varies depending on your skin condition, degree of laxity, previous treatments, and goals.

🏃 Want to live longer? The minimum may not be the optimum.

Most of us know the CDC recommends at least 150 minutes of moderate exercise (or 75 minutes of vigorous exercise) each week for overall health.

But did you know that a large study published in JAMA Internal Medicine found the greatest reduction in the risk of premature death at around 450 minutes of moderate exercise per week—about 60 minutes a day?

Participants at this level had approximately a 39% lower risk of premature death compared with people who were inactive.

The best part? You don’t have to run marathons.

Activities that count include:
✔️ Brisk walking
✔️ Cycling
✔️ Swimming
✔️ Hiking
✔️ Dancing
✔️ Tennis or pickleball

If it raises your heart rate and makes talking a little harder, it counts.

💪 Don’t forget to include strength training at least twice a week to preserve muscle, support your metabolism, and maintain independence as you age.

Remember:
✅ 150 minutes/week is the minimum recommendation.
✅ Around 450 minutes/week was associated with the greatest longevity benefit in this study.
✅ Every minute of movement counts.

What’s your favorite way to stay active? Let me know in the comments! 👇

🇰🇷 Korea’s next-level skin booster trend ✨

I’ve been in Seoul for almost two weeks, and one trend I’m seeing everywhere is that skin boosters are no longer just about choosing ONE injectable.

Instead, clinics are combining different skin boosters + different treatment modalities to target multiple aspects of skin quality at once.

One combination I’m seeing:

💧 RE2O direct injection → hydration, plumpness + overall skin quality
⚡ Potenza RF microneedling → improves texture + stimulates collagen over time
🧬 Rejuran → supports hydration, repair + overall skin quality

The idea is to address hydration + texture + collagen + skin quality in one treatment plan rather than relying on a single modality.

Downtime? Expect about 1–2 days of redness, swelling, and visible injection or microneedling marks, although this varies by person and treatment intensity.

Korean aesthetic treatments continue to become more focused on combination treatments and overall skin quality rather than simply adding volume. ✨

Would you try this combination?

🇰🇷introducing Derma-Active in Pureen

Want a more lifted-looking face? Don’t forget about the muscles underneath. 💪✨

In 🇰🇷Korea, facial rejuvenation isn’t only about tightening the skin. There’s growing interest in treatments that target both the skin and facial muscles.

At Pureen, Derma-Active combines three technologies:

⚡ Microcurrent — gentle electrical stimulation
💪 EMS (Electrical Muscle Stimulation) — stimulates facial muscle contractions to support a firmer, more toned appearance
🔥 RF (Radiofrequency) — gently heats the skin to support collagen production and improve firmness

I especially love the concept of midface muscle stimulation. As we age, changes happen not only in our skin, but also in the deeper structures that support our face.

Think of it as a workout for your face—while simultaneously working on skin quality and collagen.

No downtime. Comfortable treatment. And a very interesting addition to a well-aging routine.

🇰🇷 My personal Korea treatment plan this summer.

As a 47-year-old physician, my approach to healthy aging is simple: focus on consistency rather than chasing every new trend.

This summer, my plan includes:
• Thermage FLX for collagen maintenance
• Ultherapy for lower-face lifting
• Botox for dynamic wrinkles
• RE2O Skin Booster for my face, neck, and hands
• Radiesse to restore cheek volume while stimulating collagen

Every face ages differently, so treatment should always be individualized. This is simply the plan I personally follow to maintain healthy, natural-looking skin over time.

Healthy aging isn’t about looking younger—it’s about looking like the best version of yourself.

✨ Have you ever considered traveling to Korea for aesthetic treatments?
