Cos De BAHA Azelaic Acid 10% Serum (30 ml) – Niacinamide & Panthenol, Lightweight Aloe-Based Treatment for Blemish-Prone Skin

Cos De BAHA Premium Azelaic Acid 10% Serum is a lightweight aloe-based treatment serum formulated to help refine blemish-prone, redness-prone, and oily skin while supporting smoother, more even-looking tone and texture.

This Korean-style serum combines a high-strength 10% azelaic acid concentration with niacinamide and panthenol in an aloe leaf extract base to deliver hydration without heaviness. The formula purposefully blends humectants and botanical extracts so it layers comfortably under moisturizers and sunscreen for AM or PM use. It focuses on cosmetic improvements in pore appearance, uneven tone, and rough texture while avoiding drug claims.

How will this serum fit into a daily routine?

Apply after cleansing and any lightweight water-based treatments, then follow with moisturizer and SPF in the morning or a nourishing cream at night. Because the serum absorbs quickly, it integrates well into multi-step regimens and can be used both once or twice daily depending on tolerance.

• Use on clean, dry skin—apply 2–3 drops to face and neck.
• Layer under moisturizer; SPF is required for daytime use.
• Start with every-other-day application if you have sensitive skin.

What active ingredients are included and what do they do cosmetically?

The main active is azelaic acid at 10%, supported by niacinamide to address uneven tone and panthenol for skin comfort and moisture retention. Humectants like propanediol and sodium hyaluronate help maintain hydration while botanical extracts round out the sensory and antioxidant profile.

• Azelaic Acid 10%: cosmetic support for refining texture and tone.
• Niacinamide: helps balance the look of excess oil and post-blemish marks.
• Panthenol and humectants: improve skin feel and hydration without greasiness.

Is this product suitable for sensitive or oily skin types?

The aloe-based, lightweight formula was created to be gentle-feeling and non-greasy, making it appropriate for oily and combination skin, and potentially usable by some with sensitivity when introduced gradually. Patch testing is recommended; begin with less frequent use to assess tolerance.

• Gentle-feeling aloe base reduces heavy film on skin.
• Non-comedogenic texture suitable for oily or blemish-prone complexions.
• Introduce slowly if you have reactive or very sensitive skin.

How does the serum layer with other skincare products?

The fast-absorbing formulation layers smoothly under creams and sunscreens without pilling, and pairs well with both water-based and silicone-containing moisturizers. Avoid combining with other strong actives at first—build tolerance before mixing multiple exfoliating or acid-based products.

• Apply thin layers to minimize interaction with other actives.
• Wait a minute after applying before sealing with moisturizer or sunscreen.
• If using retinoids or strong exfoliants, alternate evenings to reduce irritation risk.

Who is this for: Cos De BAHA Premium Azelaic Acid 10% Serum is designed for people seeking a non-greasy, aloe-forward treatment to address the cosmetic appearance of blemish-prone, redness-prone, and oily skin. It suits those who want a high-strength azelaic option that layers easily into both morning and evening routines, and who prefer formulas enriched with niacinamide, panthenol, and plant-derived extracts. If you have very sensitive skin or use multiple prescription actives, introduce it gradually and consult a professional if needed.
