Ever wonder how K-Pop idols maintain their impossibly perfect, glowing skin despite their hectic schedules? It’s not just magic—it’s a combination of smart routines, powerful products, and a deep understanding of what their skin needs.
As a Seoul-based beauty expert, I’ve analyzed the routines of some of the industry’s brightest stars. In this guide, we’ll break down the real, actionable skincare secrets of 5 of K-Pop’s top female idols. Forget vague advice; we’re diving into the specific philosophies and holy grail products that you can actually use to unlock your own celebrity-level glow.
Sana (TWICE): The Master of Cleansing
If there’s one thing to learn from TWICE’s Sana, it’s that a truly flawless canvas starts with a perfect cleanse. For Sana, double cleansing isn’t just a step; it’s a non-negotiable ritual to keep her skin clear and bright.
- Ggot-song’s Expert Analysis & Pro-Tips:
I couldn’t agree more with Sana’s philosophy! Her routine is all about “Mastering the Basics + Customized Care.” Double cleansing is absolutely essential, especially if you wear waterproof makeup.- Ggot-song’s Tip: For the first step, use an oil or balm to melt away makeup. For the second, use a low-pH foam cleanser to respect your skin’s pH balance. After masking, always lock in the hydration with a ceramide cream or a drop of oil.

Many sources link Sana’s routine to the brand COSRX. A product that aligns perfectly with her philosophy is the COSRX Low pH Good Morning Gel Cleanser, which offers a gentle yet thorough cleanse.
Winter (aespa): The Science of “Glass Skin”
aespa’s Winter is famous for her flawless, radiant complexion, often described as “glass skin.” Her secret isn’t just one product; it’s a scientific approach that combines collagen-boosting with intense hydration.
- Ggot-song’s Expert Analysis & Pro-Tips:
Achieving “glass skin” like Winter’s isn’t magic—it’s science. But even the best products can’t work if your canvas isn’t prepped. The hidden enemies of glass skin are neglecting exfoliation and forgetting sunscreen, as UV rays are the biggest destroyer of collagen. My Realistic Advice: “Glass skin doesn’t happen overnight! It takes at least 8 weeks of consistent care. And don’t forget the basics: drink 2 liters of water a day and get at least 7 hours of sleep.” - Get Winter’s Look: The Key Product
The product often mentioned as Winter’s favorite is the Medicube Salmon DNA PDRN Pink Collagen Cream. It’s an all-in-one product that delivers regeneration, elasticity, and hydration.
Jang Wonyoung (IVE): The Queen of Hydration
When it comes to achieving that plump, “mochi-like” skin, IVE’s Jang Wonyoung is in a league of her own. As an ambassador for Innisfree, her routine is a masterclass in strategic hydration. Her key secret? Applying serum multiple times throughout the day.
- Ggot-song’s Expert Analysis & Pro-Tips:
Wonyoung’s “hydration bomb” routine is all about consistency. Serums packed with Hyaluronic Acid can hold up to 1,000 times their weight in water. Applying it frequently helps maintain your skin’s moisture reserves. My Realistic Hydration Tips: “A serum stick is a portable lifesaver. You can gently dab it over your foundation to combat dryness and add a subtle glow.” - Get Wonyoung’s Look: The Key Product
A star product frequently associated with her is the Innisfree Green Tea Seed Hyaluronic Acid Serum. The lightweight texture combines Hyaluronic Acid and Green Tea extract for a one-two punch of hydration and antioxidant power.
Joy (Red Velvet): The Master of “Dual Toning”
Red Velvet’s Joy’s secret lies in an advanced technique called “Dual Toning.” This two-step process tackles both exfoliation and hydration for a perfectly balanced complexion.
- Ggot-song’s Expert Analysis & Pro-Tips:
“I was intrigued by dual toning and tried it myself to combat flaky winter skin. The results were amazing! My advice for sensitive skin is to start slow. Choose a low-irritation exfoliating toner and an alcohol-free hydrating toner, and begin with just twice a week before moving to daily use.” - Get Joy’s Look: The Key Product
For the second, hydrating step of the dual toning process, a product like the Fresh Rose Deep Hydration Facial Toner is a perfect choice. It’s incredibly hydrating and gentle, making it ideal for sensitive skin.
Bonus Tip: How to Get Karina’s Flawless “AI” Skin Texture
aespa Karina’s computer-generated skin texture is a hot topic, but her routine is a well-kept secret. As a beauty expert, I believe her key isn’t just skincare—it’s a mastery of the makeup base.
- Ggot-song’s Expert Analysis & Pro-Tips:
The goal is to minimize pores and control shine for a smooth, velvet finish. 1. Primer is Power: A good silicone-based primer is fantastic for filling in uneven texture and blurring pores. My tip: don’t rub! Gently tap it into the skin for the best effect. 2. Strategic Powdering: After foundation, lightly dust a translucent powder with a large, fluffy brush to set everything and keep your T-zone looking fresh and matte all day. - Get Karina’s Look: The Key Products
For that poreless canvas, a good primer and powder are essential. I recommend the Innisfree Pore Blur Primer for smoothing and the Etude House Zero Sebum Drying Powder for a flawless, matte finish.
