Who – For Stubborn Blemishes, Redness and Uneven Tone

This MaryenB ANC10 Azelaic Acid 10% Serum is made for people who deal with more persistent blemishes, visible redness and uneven tone and are ready for a stronger azelaic acid treatment. If you have acne‑prone or redness‑prone skin that no longer responds well to very mild products, this facial serum offers a more intensive yet still daily‑friendly option. It is ideal for those who want to improve the look of post‑blemish marks and blotchy areas without using harsh scrubs or overly aggressive routines.

What – High‑Strength Azelaic Acid 10% Facial Serum

ANC10 is a concentrated azelaic acid 10% facial serum with niacinamide and Centella asiatica (cica) designed to support clearer‑looking, more balanced skin. This high‑strength azelaic acid serum targets common concerns such as recurring breakouts, visible redness and uneven texture that often remain after blemishes fade. It focuses on helping the skin look smoother and more even over time while supporting the skin barrier.

How – How This Serum Helps With Redness, Blemishes and Marks

The 10% azelaic acid in this serum works to help reduce the look of congestion, refine the appearance of pores and improve the look of stubborn blemishes and post‑blemish marks. When combined with niacinamide, it also helps support a stronger barrier and a more even‑looking complexion, which can be especially helpful for skin that easily looks red or inflamed. Cica (Centella asiatica extract), panthenol and soothing plant extracts are included to comfort the skin so that, with regular use, redness‑prone and acne‑prone skin can appear calmer and more balanced.

Hero ingredients – Focused Formula for Problem‑Prone Skin

The hero ingredients in MaryenB ANC10 are selected to work together on problem‑prone skin without feeling overly heavy.

• 10% azelaic acid to help improve the look of persistent blemishes, visible redness and uneven texture.

• 1% niacinamide to support the skin barrier and help refine tone and pores.

• 1% Centella asiatica (cica) extract to give a soothing feel to skin that often looks irritated.

They are supported by sodium hyaluronate for lightweight hydration, panthenol for skin comfort and resilience, and botanical extracts such as green tea, oat and Houttuynia cordata to create a gentle, supportive base for daily use.

Texture & routine – Lightweight Yet Potent Daily Serum

Despite its strength, this azelaic acid 10% serum has a light, fluid texture that absorbs quickly without feeling greasy or sticky on the skin. After cleansing and using a gentle toner, apply a small amount of MaryenB ANC10 serum over the face, avoiding the immediate eye area, then follow with a soothing moisturizer. For most users, evening use is recommended first; once the skin is comfortable with the formula, some may choose to use it several times per week. When used in a morning routine, always finish with a broad‑spectrum sunscreen, as daily sun protection is essential when working on visible discoloration.

Who should avoid – When to Choose a Gentler Option

Because ANC10 is a high‑strength azelaic acid serum, very sensitive or highly reactive skin types may find it too strong for daily use. If your skin barrier is already compromised, you are experiencing significant peeling or stinging, or you are new to active ingredients, it is usually better to start with a lower concentration such as ANC5. Anyone with a history of sensitivity to azelaic acid, niacinamide or Centella asiatica should patch test carefully before applying this serum to the entire face, and those using prescription treatments or strong exfoliating acids should introduce ANC10 slowly and stop use if strong burning, intense redness or persistent discomfort occurs.
