Anua - Azelaic Acid 10 Hyaluron Redness Soothing Serum

Step 1 — Cleanse and Tone
Apply after cleansing and toning, between your toner and moisturiser steps.

Step 2 — Start with 1–2 Drops
Begin with 1–2 drops per application. The watery formula distributes easily — a small amount covers the full face. Increase to up to 5 drops per application as skin tolerance builds.

Step 3 — Pat Gently into the Skin
Apply drops to the fingertips and gently pat across the face, focusing on areas of redness, congestion, and dark marks. Allow to absorb fully before the next step.

Step 4 — Follow with Moisturiser
Apply moisturiser to seal in the serum and provide additional barrier support — particularly important during the initial weeks of use when the skin is adjusting to 10% Azelaic Acid.

Step 5 — Build Frequency Gradually
Begin 1–2 times per week. Increase gradually over 2–4 weeks based on skin response, building toward daily AM and PM use. This gradual introduction is the single most effective strategy for avoiding adjustment-period sensitivity.

Step 6 — Always Apply SPF in the Morning
Azelaic Acid increases photosensitivity during cellular turnover — daily SPF 30 or greater is essential when using this serum in the morning routine.

Azelaic Acid — The Rare Active That Treats and Soothes Simultaneously
Every other effective exfoliating and brightening active — AHAs, BHAs, retinoids, Vitamin C — has the potential to aggravate sensitive and reactive skin. Azelaic Acid is the exception: its anti-inflammatory mechanism means that as it clears congestion, fades dark spots, and smooths texture, it is simultaneously reducing the inflammation and redness that sensitive skin is fighting. For UK skin that is already reactive from environmental pollution, hard water, and central heating — this is not a compromise active. It is the right active.

Gentle Calming Complex™ — Blue Tansy + 7 Types of Cica
The combination of Blue Tansy Oil, Ubiquinone, Green Tea, Aloe, and the full spectrum of Centella Asiatica bioactive compounds creates one of the most comprehensive soothing complexes in K-Beauty. The natural green colour is the functional evidence of this complex — not a dye, not a marketing choice, but the genuine botanical colour of Blue Tansy and Cica at meaningful concentrations. It is the visual promise that these ingredients are present at levels that work.

Three Hydration Systems — Hyaluronic Acid + Biosaccharide Gum-1 + Squalane
The formula addresses hydration across three different mechanisms: HA and Biosaccharide Gum-1 drawing and retaining water from the environment and deeper skin layers; Squalane forming a lightweight lipid seal that prevents moisture from escaping. The result is a genuinely hydrating treatment serum — not one that dehydrates the skin while it treats.

Buildable from Twice Weekly to Twice Daily
Starting at 1–2 times per week and gradually building to daily AM and PM use gives the skin time to acclimate to 10% Azelaic Acid without the adjustment-period irritation that can occur when introduced too quickly. The formula's built-in soothing complex makes this build significantly more comfortable than conventional Azelaic Acid products — many users reach daily use within 2–3 weeks without any irritation period.

Non-Comedogenic Tested — Safe for Acne-Prone Skin
The non-comedogenic certification means this serum will not clog pores or contribute to the congestion it is working to clear — essential credibility for a serum marketed to acne-prone skin, and not something every treatment serum can claim.

Fragrance-Free and Free from 7 Irritants
Complete absence of artificial fragrance, denatured alcohols, artificial colour, oils, silicones, sulphates, and parabens makes this one of the cleanest treatment serums in the ANUA range. For UK skin dealing with reactive sensitivity, the elimination of fragrance in particular significantly reduces the risk of a reactive response to a new active product.

All skin types. Especially suitable for sensitive, reactive, redness-prone, and acne-prone skin.

Q: Why is this serum green?
A: The natural green colour comes from Blue Tansy Oil in the Gentle Calming Complex™ — no artificial dyes.

Q: Is 10% Azelaic Acid safe for sensitive skin?
A: Yes — Azelaic Acid is anti-inflammatory, making it one of the most sensitive-skin-appropriate actives available.

Q: Can I use this on rosacea-prone skin?
A: It is suitable for rosacea-adjacent sensitivity; those with diagnosed rosacea should consult a GP or dermatologist first.

Q: How is Azelaic Acid different from AHA or BHA?
A: Unlike AHAs and BHAs, Azelaic Acid reduces inflammation rather than potentially increasing it — making it tolerable for reactive skin.

Q: Can I use this with the ANUA Niacinamide + TXA serum?
A: Yes — use on alternate evenings for comprehensive brightening without overloading the skin with actives.

Q: Can I use this with retinol?
A: Not on the same night — use Azelaic Acid and retinol on alternate evenings.

Q: Is this fragrance-free?
A: Yes — completely free from artificial fragrance and artificial colour.

Q: Can I use this while pregnant or breastfeeding?
A: Consult your GP or midwife first — Azelaic Acid is generally considered lower-risk but professional guidance is recommended.

Q: How quickly will redness reduce?
A: Clinically proven to immediately (temporarily) calm redness after application; sustained reduction builds within 4 weeks.

Q: Where does this go in my routine?
A: Between toner and moisturiser — AM and PM.
