For Skin Sensitive to Retinol: Azelaic Acid, the Third Option

🧪 Gentle yet effective care for acne scars and redness
🎯 For Skin That Had to Give Up on Retinol and Vitamin C Due to Irritation
You can't continue using retinol because you're worried about the retinol reaction (peeling).
Vitamin C stings and causes redness.
For those with sensitive skin, azelaic acid is currently attracting attention in Korea.
It is increasingly being chosen as a relatively gentle ingredient that can address three concerns: acne, redness, and the prevention of dark spots.
In this article, we’ll explain the characteristics of azelaic acid, tips for using it, and what to look for when choosing a product.
🧬 What Is Azelaic Acid? 3 Ways It Helps Improve Your Skin
Azelaic acid is a naturally derived acid (dicarboxylic acid) found in wheat, rye, and other grains.
It has also been used overseas to treat acne and rosacea (facial redness), and in Korean cosmetics it primarily targets three concerns.
✅ ① For Recurring Acne and Excess Sebum
It gently helps regulate the dead skin cells that can cause clogged pores and suppresses the growth of acne-causing bacteria. Some people also report less shine in the T-zone (individual results may vary).
✅ ② Soothing Red Acne Scars and Facial Redness
It helps calm inflammation and may help even out the appearance of skin prone to noticeable redness, including redness left behind after acne heals.
✅ ③ Preventing Dark Spots and Melasma
It blocks the activity of tyrosinase, the enzyme responsible for melanin synthesis. Since it is known to work on activated melanocytes, it can target dark-spot care while minimizing stress on the skin. Results vary depending on the condition.
📊 How Is It Different from Retinol and Vitamin C?
In short, the key difference is that azelaic acid is relatively gentle and can also be used in the morning.
Retinol is highly effective for wrinkles and firmness, but carries a risk of peeling and redness, so nighttime use is recommended.
Pure vitamin C is appealing for its ability to brighten dull skin quickly, but some people may experience stinging (individual results may vary).
Azelaic acid, on the other hand, is mild enough that you may experience only slight itching and can also be used in the morning (UV protection required). Its natural origin is another reason people choose it.
As for use during pregnancy, a doctor’s advice is required. We recommend consulting a medical professional in advance rather than making the decision yourself.
💡 What to Look for When Choosing Azelaic Acid, the Third Skin-Improving Ingredient
The key points to consider are the concentration and the balance of the other ingredients included.
Among Korean cosmetics, products containing 10% azelaic acid are particularly popular.
Brands such as Cos De BAHA, Nineless, and Derma Factory are releasing a steady stream of serums containing 10% azelaic acid.
✅ Look for Combinations with Niacinamide
Using azelaic acid together with niacinamide, which is suited to sebum and hyperpigmentation care, may provide a multifaceted approach. Cos De BAHA’s AZ Azelaic Acid 10% Serum is supported as a product that combines these two ingredients in a well-balanced formula. Its rich, viscous texture is appreciated by some users who notice a smooth, non-sticky feel the following morning (individual results may vary).
📝 What to Confirm Beforehand
Because this is intensive care, it is important to make the necessary checks before getting started.
✅ Check Before You Start Using It
・If you have sensitive skin or skin concerns, consider doing a patch test first
・Consult a doctor before use during pregnancy or breastfeeding
・If you want to use it with retinol, consider separating the times of use—for example, azelaic acid in the morning and retinol at night
・Don’t forget sunscreen on days you use it in the morning
