The art of holiday skin prep. 🕊️ Unwinding with the Dior Ox-C Treatment Creme for that glass-skin radiance.

Your face is a living ecosystem and acne occurs when the microbiome is disrupted.
If you are stuck in a cycle of constant breakouts, the answer may not be a stronger acid but restoring the balance. ⚖️

POV: You finally stopped fighting texture and started fixing your prep. ☁️✨

The biggest lie in beauty is that you need more coverage to hide textured skin. As a dermatologist, I can tell you that 90% of the “texture” you see isn’t scarring or pores—it’s dehydration at the micro level.
When your skin barrier is thirsty, dead skin cells lift slightly (micro-flaking). If you put heavy matte foundation over that, it catches on every edge, looking cakey within an hour.
Here’s my skin-first quick fix.
1️⃣ The Damp Skin Rule: Never touch dry skin with makeup. I prep with the Mineral Booster facial mist first, which is a Polyglutamic Acid based primer (it holds 4x more moisture than HA). That’s the first step to create a smooth, gripping canvas.
2️⃣ Micro-Conceal: Stop masking your whole face. Only spot-correct the shadows (eyes, nose, blemishes). Let your real skin breathe everywhere else.
3️⃣ Strategic Shine: Powder only the T-zone. Leave the cheeks dewy to reflect light—this mimics the natural light bounce of collagen-rich, youthful skin.
Makeup should look like silk, not a mask.

For centuries, Panax Ginseng was reserved for the Imperial Court. It was the original bio-hack for longevity and radiance, revered in Traditional Chinese Medicine (TCM) for its ability to harmonize the spirit.

In this series, I reveal the science of ancient herbals under the lens of modern ethnopharmacology. We learn how Ginsenosides and Gintonin actually interact with your skin barrier to mimic that ancient glow from within.

Ginseng acts similarly to engineered peptides when it comes to collagen function, activating the Smad signaling pathway.

This directly triggers the COL1A2 promoter—the gene responsible for synthesizing fresh Type I Procollagen.

Panax Ginseng is an ethnobotanical with traditional uses, but modern science has also unveiled its dual-action modulation on the fibroblast. It upregulates the COL1A2 gene via the Smad signaling pathway, mimicking collagen and cell repair signals.

It also significantly inhibits MMP-1, the primary enzyme responsible for breaking down Type I collagen fibers.

In our CellTalk CC Cream , I paired the botanical extract with synthetic actives such as
Palmitoyl Pentapeptide-4 and adenosine.

By combining MMP Inhibition (Ginseng) with Direct Peptide Signaling (Palmitoyl Pentapeptide-4 + Adenosine), the formula achieves a synergistic effect that single-active products often miss.

For centuries, texts revered Panax Ginseng, also known as the ‘Emperor’s Root.’ as the ultimate source of 气 (qì), or “vital energy.”

As a dermatologist, I interpret these ancient texts as a fascinating observation of a powerful adaptogen at work.

Modern studies have elucidated the active compounds Ginsenosides and Gintonin which have been shown to preserve collagen loss, fortify the skin barrier, and accelerate cellular repair.

Save this post if you, too, believe in cultivating resilience, not just concealing flaws.

The #1 struggle in humid climates? Then feeling dry and dehydrated in AC? 🥵 Wanting that glass-skin glow... but ending up a greasy, makeup-sliding mess by 10 AM is a common woe in tropical Singapore weather!

Meet the Radiance Fluide™ Hydrating Emulsion, which is formulated precisely to balance the skin microclimate with ethnobotanicals and peptides- clinically tested and validated over seven years in my Singapore dermatology practice. It’s a lightweight postbiotic barrier lotion designed for humidity that protects the delicate skin microenvironment and microbiome.

It’s also formulated as a 3-in-1 solution to simplify your routine:
1. A Hydrating Toner
2. A Satin-Feel Makeup Base (no pilling!)
3. A Restorative Sleeping Mask
This milky, breathable lotion gives instant hydration without the sticky, heavy feel.

Why it works:

• 🧬 Repairs: A Postbiotic Ferment Complex supports a healthy, calm skin barrier.
• 🌱 Soothes: A Neuro-Comfort Botanical Complex brings relief to sensitive skin.
Stop the grease. Keep the glow.

Class is in session! 🔔 🐾 The biggest mistake I see during 11.11? Buying too many random skincare actives because they’re on sale. 😱

Your skin doesn’t want chaos; it wants consistency. Mixing too many harsh acids from different brands is a fast track to a damaged skin barrier. 🛑

💡 Derm Lesson for 11.11: Smart shoppers don’t just buy “products”—they buy Protocols.

A Protocol is a system where every ingredient (like our Phyto-Soothe™ and 5α-Control complexes) is formulated to work synergistically—giving you maximum results with zero confusion.

Ready to get an A+ in skincare shopping? I’ve curated my top science-backed Protocols for every skin concern in our biggest sale of the year.

Did you know Vitamin C can clear ACNE? 🤯
Standard L-ascorbic acid might break you out, but 5% Sodium Ascorbyl Phosphate (SAP) is clinically proven to inhibit acne bacteria while brightening your skin. It’s the ultimate dermatologist hack for acne-prone skin.
👇 Comment ACNE below and I’ll DM you the link to this 2-in-1 formula.

Do. Not. Pick.

As a dermatologist, I don’t just see the blemish—I see the inflammation, Post-Inflammatory Hyperpigmentation (PIH) and scarring that follows.

I was frustrated by harsh, drying treatments that only made things worse—-antibiotic resistance too!

That’s why we embarked on a journey to create a microbiome-first dermocosmetic solution that interrupts the blemish cycle. Used for spot treatment and acne-prone area control. It’s now completed its 7th year of clinical evaluation, and we’re ready to deliver it to you!

The Blemish Spot Cream uses three synergistic bio-complexes to:
1. CONTROL the vicious cycle of oiliness.
2. CALM visible redness and inflammation instantly.
3. RENEW the skin’s barrier and microbiome to heal.

It’s powered by 18 ethnobotanical extracts and 4 bioferments to heal the spot and, most importantly, help prevent the scar, it targets the clogging and congestion as well, in addition to targeting blackheads and sebaceous filaments.

This is my lab protocol, now in your hands. Get my solution👆
