Azelaic Acid vs Tranexamic Acid — what they are & what they help with
TXA vs. Azelaic Acid: Which One Does Your Skin Really Need?
If you’ve been scrolling through skincare TikTok or diving deep into K-beauty, you’ve probably noticed two ingredients taking center stage lately: Tranexamic Acid (TXA) and Azelaic Acid. Both are incredible for brightening, calming redness, and improving uneven tone — but they work in different ways and suit different skin types.
Let’s break down what they actually do and how to pick the one that fits your skin best.
💧 What is Tranexamic Acid (TXA)?
Originally used in medicine to reduce inflammation and control bleeding, Tranexamic Acid found its way into skincare because of its impressive brightening and anti-inflammatory effects.
In skincare, TXA helps:
-
Fade dark spots, hyperpigmentation, and melasma
-
Calm post-acne marks
-
Brighten dull skin
-
Support a stronger, more even skin tone
It’s a gentler alternative to strong brighteners like hydroquinone, which makes it ideal for sensitive skin that can’t tolerate harsh treatments.
Try:
-
Medicube Tranexamic Acid Serum – a lightweight formula packed with TXA to target dark spots and pigmentation while keeping skin calm and hydrated.
-
Anua Niacinamide 10% TXA 4% Serum – focuses on tone correction and glow, perfect for dull or tired-looking skin.
🌿 What is Azelaic Acid?
Azelaic Acid is a naturally occurring acid found in grains like barley and rye. It’s a true multitasker that helps with acne, rosacea, redness, and uneven skin tone — all at once.
What it does:
-
Reduces inflammation and redness
-
Gently exfoliates dead skin cells
-
Fades post-acne pigmentation
-
Fights acne-causing bacteria
-
Helps regulate oil without drying
Because it’s so versatile, Azelaic Acid works for acne-prone, sensitive, or redness-prone skin.
Try:
-
Anua Azelaic Acid 10% + Hyaluron Serum – a gentle daily formula that soothes redness, fades marks, and hydrates at the same time.
-
Anua Azelaic 10 Hyaluron Redness Soothing Pad - – ideal for quick, mild exfoliation and tone correction without irritation.
⚖️ TXA vs. Azelaic Acid: Which Should You Choose?
If your main concern is dark spots, sun damage, or melasma, go for TXA.
If you’re dealing with acne, redness, or uneven texture, Azelaic Acid will be your best friend.
That said, the two ingredients actually work beautifully together — TXA brightens from within, while Azelaic Acid smooths and calms the surface. Many skincare enthusiasts layer or alternate them for a balanced, healthy glow.
✨ Food for Though:
Both TXA and Azelaic Acid deserve a spot in your skincare routine — it just depends on what your skin needs most right now.
If you’re just starting out, try introducing one at a time to see how your skin reacts.
For tone and glow: go with Anua TXA Serum or Medicube TXA Serum.
For redness and texture: start with Anua Azelaic Acid Serum or Anua Azelaic Toner Pads.
No harshness, no irritation — just calmer, more even skin.
