Who – For Sensitive, Redness‑Prone, Acne‑Prone Skin

This MaryenB ANC5 Azelaic Acid 5% Serum is made for sensitive, redness‑prone and acne‑prone skin that needs gentle daily care. It is a good choice if your skin flushes easily, shows small breakouts and uneven texture, but you still want a calm, simple routine you can use every day. Instead of harsh exfoliants, this azelaic acid facial serum focuses on helping your skin look more even, less red and more comfortable over time.

What – Azelaic Acid 5% Facial Serum for Daily Barrier Support

ANC5 is a lightweight azelaic acid 5% facial serum with niacinamide and Centella asiatica (cica) designed to support a healthy skin barrier. It targets common concerns of sensitive and acne‑prone skin such as visible redness, post‑blemish marks and rough texture. The goal is a balanced, smoother‑looking complexion that feels calmer day after day.

How – How This Serum Calms Redness and Blemishes

The 5% azelaic acid in this serum helps control excess oil, refine the look of pores and reduce the appearance of blemishes and post‑blemish marks. Niacinamide works alongside it to support the skin barrier, improve the look of uneven tone and keep the surface feeling smoother. Cica (Centella asiatica extract), panthenol and gentle plant extracts help soothe visible irritation so redness‑prone skin can gradually appear more at ease with consistent use.

Hero ingredients – Focused, Sensitive‑Skin Friendly Formula

The hero ingredients in this azelaic acid serum are kept focused and sensitive‑skin friendly.

• 5% azelaic acid to support clearer‑looking, less congested skin.

• 1% niacinamide to reinforce the barrier and improve tone and texture.

• 1% Centella asiatica (cica) extract to provide calming comfort.

These are supported by sodium hyaluronate for lightweight hydration, panthenol to help keep skin soft and resilient, and plant extracts such as green tea and oat to create a gentle, supportive environment for stressed skin.

Texture & routine – Light, Layer‑Friendly Daily Serum

The texture of this azelaic acid 5% serum is light, fluid and non‑sticky, so it absorbs quickly and layers well under moisturizer, sunscreen and makeup. After cleansing and toning, apply one to two pumps of MaryenB ANC5 serum over the face, then follow with your favorite hydrating cream. You can use it in the evening or both morning and night; if you use it in the morning, always finish with a broad‑spectrum sunscreen.

Who should avoid – When to Patch Test or Skip

Although ANC5 is formulated with sensitive skin in mind, not every skin will react the same way to azelaic acid. If your barrier is very compromised, your skin is peeling or stinging, or you have a known allergy to azelaic acid, niacinamide or Centella asiatica, start with a patch test and slow introduction. If you are already using strong exfoliating acids, high‑strength retinoids or prescription treatments, simplify your routine and introduce this serum gradually, and stop use if you notice strong burning, intense redness or persistent discomfort.
