Anua offers four very different serums, and confusing their active ingredients is the most common mistake we see among customers who write to us for advice.
Each Anua serum targets a specific skin need. The Niacinamide 10% + TXA 4% works on spots and blemishes, the Peach 70% Niacin revives dull complexions, the Azelaic Acid 10% soothes redness, and the Green Lemon Vitamin C brightens an uneven complexion. The right choice depends on your goal, not on the product's popularity on social media.
Faced with four formulas that look similar on paper, it's easy to choose the wrong serum, or worse, to layer them all, thinking you'll get better results. This guide helps you identify the right formula for your skin, integrate it correctly into your routine, and avoid common mistakes when combining several Korean active ingredients.

The 4 Anua serums at a glance 🔍
Before going into detail about each formula, here's how the four serums are categorized by their target.
| Serum | Main Active Ingredient | Target | Recommended Skin Type |
|---|---|---|---|
| Niacinamide 10% + TXA 4% | Niacinamide, tranexamic acid | Spots, blemishes, pores | Combination to oily |
| Peach 70% Niacin | Peach extract, niacinamide | Dull complexion, lack of radiance | Normal to dry |
| Azelaic Acid 10% + Hyaluron | Azelaic acid, hyaluronic acid | Redness, sensitivity | Sensitive, reactive |
| Green Lemon Vitamin C | Vitamin C, green lemon extract | Uneven complexion, spots | All skin types |
Niacinamide 10% + TXA 4% for spots and blemishes ✨
The Niacinamide 10% + TXA 4% is the Anua serum to choose if your main goal is to reduce pigment spots and post-acne marks. Niacinamide regulates sebum production and calms inflammatory redness, while tranexamic acid (TXA) interrupts the mechanism that triggers hyperpigmentation.
Concretely, this combination acts on two levels: it limits the appearance of new imperfections while gradually fading existing scars. It is the most versatile serum in the range, because it treats both the cause (excess sebum, inflammation) and the visible consequence (spots).

In use, the texture is fluid and slightly milky; it penetrates in a few seconds without leaving a sticky film under cream. This is an important point if you wear makeup afterward, as a serum that's too rich at this stage complicates foundation application. Recent marks generally fade first; old scars require more patience and regular use over several months for a clear result.
Targeted skin types: combination to oily, prone to breakouts or marks that persist after an acne flare-up. (view Niacinamide 10% + TXA 4% serum)
Peach 70% Niacin to revive a dull complexion 🍑
If your skin looks tired rather than problematic, the Peach 70% Niacin addresses a different need: restoring radiance without irritation. Peach extract provides antioxidants that protect the skin from oxidative stress, the main culprit for dull complexions throughout the seasons.
The niacinamide in the formula refines skin texture and tightens the appearance of pores, while strengthening the skin barrier. It is a maintenance serum rather than a targeted treatment, designed for long-term daily use.
The texture is creamier than that of Niacinamide 10% + TXA 4%, with a light fruity scent that remains discreet once absorbed. It's a serum that comforts tight or dehydrated skin, without replacing a moisturizer afterward. The healthy glow effect is usually visible from the first few days, while the skin texture regulation takes several weeks of consistency.
Targeted skin types: normal to dry, seeking comfort and radiance rather than correction. (view Peach 70% Niacin serum)
Azelaic Acid 10% + Hyaluron to soothe redness 🌿
Azelaic acid is one of the few active ingredients that is anti-inflammatory, anti-blemish, and brightening, without the drying effect of many exfoliants. At 10%, it remains at a concentration well-tolerated by sensitive skin, unlike some more concentrated pharmaceutical formulations.
Hyaluronic acid compensates for the potentially drying effect of azelaic acid by providing immediate hydration. This combination makes it the Anua serum most suitable for reactive skin, prone to nascent rosacea or diffuse redness.

The texture is a little denser than the previous two serums, without being sticky, and the hyaluronic acid leaves an immediate feeling of comfort that reassures tight skin. A slight sensation of warmth or tingling in the first few minutes is normal for the first few days, generally disappearing within one to two weeks of regular use. If it persists beyond that, it is better to space out applications rather than stopping completely.
Targeted skin types: sensitive, reactive, or prone to redness that appears for no apparent reason. (view Azelaic Acid serum)
Green Lemon Vitamin C for an uneven complexion 🍋
The Green Lemon Vitamin C combines vitamin C and green lemon extract to target an uneven complexion rather than localized spots. It mainly acts as a daily protective antioxidant, complementing a more targeted anti-spot routine if your marks are prominent.
It is a lesser-known serum than the previous two in the Anua range, but relevant if your priority is an overall healthy glow rather than treating specific imperfections. It suits all skin types, including sensitive skin, provided it is introduced gradually.
Targeted skin types: all, particularly as a complement to a routine focused on complexion uniformity. (view Green Lemon serum)
How to properly use your Anua serum daily ⏰
The order of application is as important as the choice of serum. Apply it to clean skin, after cleansing and toning, and before moisturizing cream. Two to three drops are enough for the entire face; a more generous amount does not make the product more effective.
For frequency, Niacinamide 10% + TXA 4% and Peach 70% Niacin are well tolerated morning and evening from the start. Azelaic Acid 10% should be introduced more gradually, every other evening for the first week, to get the skin accustomed. Allow three to four weeks before seeing a first visible improvement on spots, and six to eight weeks for a stabilized result.
If you use a vitamin C serum in the morning, never forget sun protection afterward, as these two steps go hand in hand. In the evening, it's the best time for Azelaic Acid 10% or a targeted anti-spot routine; the skin regenerates overnight and tolerates the most active ingredients better. Avoid applying a new serum immediately after an exfoliation or peel, as the skin is more permeable and the risk of irritation increases significantly on that day.
Can you combine several Anua serums? Mistakes to avoid ⚠️
Expert's advice: The most common mistake we observe is wanting to use three or four Anua serums at the same time to speed things up. This is a trap; the skin receives too many active ingredients at once and often reacts with irritation or breakouts, the opposite of the desired effect. Choose a main serum according to your dominant need, and only add a second active ingredient if your skin tolerates it well after several weeks.
Niacinamide and azelaic acid generally combine well. However, combining vitamin C and azelaic acid on the same day can irritate sensitive skin; it's better to alternate them morning and evening or use them on different days.
What to remember 📝
The right Anua serum is chosen according to your goal, not the product's popularity: spots and blemishes for Niacinamide 10% + TXA 4%, dull complexion for Peach 70% Niacin, redness and sensitivity for Azelaic Acid 10%, uneven complexion for Green Lemon Vitamin C.
A single targeted serum, used regularly, yields better results than several active ingredients combined from the start.
