What Is the Anua Serum Discovery Trio?
The Anua Serum Discovery Trio is a travel kit featuring three Anua serums, a South Korean brand known for gentle, effective formulas made with clean, clinically tested ingredients. Anua focuses on ingredient safety and minimalism, though the term “clean” can mean different things in the skincare world and is still debated by experts. Each bottle holds 10ml (0.33 fl oz) of serum, making them easy to take through airport security while still being effective.
The three serums included are:
- Niacinamide 10% TXA 4% Serum, the pink bottle, focused on glow and clarity.
- Azelaic Acid 10 Hyaluron Redness Soothing Serum, the green bottle, focused on calming and clearing.
- PDRN Hyaluronic Acid Capsule Serum, focused on deep hydration and plumping
Together, these serums focus on brightening, soothing, and hydrating—the three main steps for achieving the “glass skin” look that Korean skincare is known for.
Breaking Down Anua Serum Discovery Trio: The Korean Skincare Kit That Does It All in Three Tiny Bottles.
1. Niacinamide 10% TXA 4% Serum (The Pink Bottle)
This serum is great for brightening. It blends 10% Niacinamide with 4% Tranexamic Acid (TXA), two proven ingredients that work together to even out skin tone, reduce dark spots and hyperpigmentation, and give your skin a healthy glow. It also has Arbutin, another brightening ingredient, making it one of the most complete anti-dark-spot formulas in K-beauty.
Niacinamide, a type of Vitamin B3, is popular in skincare because it does so much: it helps control Oil, shrinks the look of pores, strengthens the skin barrier, and calms inflammation, all while brightening your skin. Tranexamic Acid was first used in medicine to reduce bleeding. Still, now it’s valued in skincare for gently fading melasma, post-acne marks, and sun damage, often with less irritation than other options like hydroquinone.
People with stubborn dark spots and uneven skin tone often say this serum makes a real difference in their skin’s look and feel after a few weeks of regular use. One person called it “a true game-changer for dark spots,” and noticed clearer, more even skin with continued use.
Who it’s for: Anyone dealing with hyperpigmentation, uneven tone, dullness, or post-breakout marks.
2. Azelaic Acid 10 Hyaluron Redness Soothing Serum (The Green Bottle)
This serum is the gentle option in the set. With 10% Azelaic Acid and Hyaluronic Acid, it helps calm redness, smooth rough skin, and clear up blemishes, all without irritation.
Azelaic Acid is a natural ingredient found in grains like barley and wheat. It’s well-known in skincare for doing many things at once: it fights bacteria, reduces inflammation, and gently helps remove dead skin cells, clearing pores and smoothing skin texture. It’s usually safe for sensitive skin and has been shown in studies to reduce acne and improve skin clarity over time.
With Hyaluronic Acid, Centella Asiatica extract, Allantoin, Beta-Glucan, Ceramide NP, and Squalane, this serum is more than just an acid treatment. It truly soothes and nourishes the skin while helping to clear it. People with acne-prone skin have noticed less redness and inflammation; one reviewer said their “pimples started to calm down, the redness faded little by little,” and that their skin became smoother after using it regularly.
Who it’s for: Sensitive, acne-prone, or redness-prone skin. Excellent for anyone in the middle of a breakout or dealing with post-acne inflammation.
3. PDRN Hyaluronic Acid Capsule Serum (The Plumping Serum)
This serum is the best for hydration in the set. It contains Salmon PDRN (Polydeoxyribonucleotide), Collagen, and five types of Hyaluronic Acid to deeply moisturize, plump the skin, and help it retain moisture over time.
PDRN is a modern ingredient made from salmon DNA and has been used in skin treatments for years because it helps skin repair itself. In skincare, it supports renewal, improves firmness, and works well with Hyaluronic Acid to hydrate. The five types of Hyaluronic Acid in this serum reach different layers of the skin, so you get both surface smoothing and deeper plumping.
Clinical tests show this serum gives real results: people noticed fuller, bouncier cheeks and smoother skin, especially around fine lines near the mouth. Skin felt more hydrated right away, with a big boost in softness and that ‘glass skin’ look. After two weeks, the skin also looked brighter and more even.
Who it’s for: Dehydrated, dull, or aging skin. Also ideal for use after the other two serums as a moisture-sealing final step in a serum routine.
Why the Three Serums Work So Well Together
What makes this trio special isn’t just the formulas themselves, but how well they work together. These three serums are meant to be used as a complete, targeted routine:
The Niacinamide TXA Serum helps brighten and clear the skin. The Azelaic Acid Serum soothes, calms, and clears up blemishes. The PDRN Hyaluronic Acid Serum hydrates and plumps. Used together, they form a balanced routine that tackles uneven tone, redness, acne, and dryness, without worrying about mixing harsh ingredients.
All three serums follow Anua’s main values: they’re lightweight, non-sticky, and absorb well. They’re also fragrance- and color-free, making them good for sensitive skin, and they use clean, clinically tested ingredients. The set has passed skin irritation tests, so people with sensitive skin can feel more confident using it.
The Travel Angle: Why Size Actually Matters Here
One of the best things about this set is the 10ml size. Each bottle is well under the TSA’s 100ml (3.4 fl oz) limit for carry-on liquids, so that you can take the whole set on a plane without any hassle. This is a big plus for frequent or business travelers, as well as anyone packing for a weekend trip.
The small size is also great for trying out the products. Instead of buying three full-size bottles, which can be expensive, the Discovery Trio lets you test each formula and see how your skin reacts before committing. It’s not often that a travel size doesn’t feel like a compromise.
Who Is This Set For?
The Anua Serum Discovery Trio genuinely covers a wide range of skin types and concerns, but it’s particularly well-suited to:
- K-beauty beginnerswho want to start with tried-and-trusted formulas from a reputable brand without a major financial commitment.
- Sensitive and acne-prone skin typeswho want effective ingredients that won’t strip or irritate. Azelaic Acid and Niacinamide are among the best-tolerated options for brightening and clarifying.
- Frequent travelerswho want a complete, effective skincare routine that fits in a carry-on or toiletry pouch.
- Skincare fans who want to see if these popular Anua formulas suit theirskin before buying the full-size versions.
- Gift-giverswho want a thoughtful, practical, and high-quality skincare present. The set is clean, nicely packaged, and works for most skin types.
How to Use the Trio
Use these serums after cleansing and toning your skin. Put a few drops of the serum you want on your fingertips and gently pat it in. You can use them one at a time, depending on your skin’s needs, or layer them by starting with the lightest and letting each one absorb before adding the next.
You can use all three serums in the morning and at night. If you use the Niacinamide TXA or Azelaic Acid serum in the morning, always follow with SPF 30 or higher, since these ingredients can make your skin more sensitive to the sun. As with any new product, start slowly—try using them 1 to 2 times a week at first, especially the Azelaic Acid serum, and then increase as your skin gets used to them.
The Verdict
The Anua Serum Discovery Trio: The Korean Skincare Kit That Does It All in Three Tiny Bottles is one of those rare product sets where the sum is genuinely greater than its parts. Each serum is impressive on its own, but together they form a cohesive, targeted routine that addresses brightening, soothing, and hydration with clinical-grade ingredients, and a sensory experience that never feels heavy or complicated.
Because these serums are fragrance- and color-free, they’re great for sensitive skin. The travel size makes them easy to use in daily life. Plus, Anua’s reputation for gentle, effective, and clean formulas means these small bottles deliver impressive quality.
