Meder Eu-Seb Normalising Anti-Acne Mask

Acne-prone skin doesn’t always need something stronger. Sometimes it needs something calmer.

Eu-Seb Mask is MEDER’s intensive sheet mask for oily and acne-prone skin, designed to calm inflammation, reduce excess sebum, support a healthier skin environment and leave the complexion fresher and more matte — without aggressively stripping it.

Think: calm → hydrate → rebalance → mattify → support.

Each box contains 5 individually packed masks.

Who is it for?

Oily skin • acne-prone skin • congested skin • inflamed blemishes • enlarged-looking pores • combination skin • dehydrated oily skin • adult acne • periodic breakouts. Suitable for use during pregnancy and breastfeeding.

Oily ≠ well hydrated

Sebum is oil. Hydration is water. They are not the same. Oily skin can be dehydrated — and aggressive over-cleansing makes this worse. Eu-Seb helps normalise the environment, not turn oily skin into dry skin.

MEDER’s microbiome philosophy

Acne doesn’t mean your skin is dirty. The goal isn’t to sterilise the face — it’s to create conditions where a healthier, more balanced microbiome can thrive. Eu-Seb focuses on calming, rebalancing and supporting, not stripping.

Key ingredients

Prebiotic & probiotic complex — supports a healthier microbial environment and reduces conditions that favour breakouts. Sebum-regulating actives — MEDER states the mask helps reduce sebum and maintain a more matte complexion for several days after use. Anti-inflammatory components — calms redness and irritation around blemishes. Hyaluronic Acid — maintains hydration while rebalancing.

How to use

1. Cleanse gently. Apply Eu-Seb Active Serum first if using.
2. Position mask and secure ear loops; tuck lower section under chin.
3. Leave for approximately 20 minutes.
4. Remove and do not rinse — massage remaining gel into the skin.
5. Finish with your MEDER moisturiser.

Use once or twice per week. Each sheet is single-use. Can be used on active breakouts.

Eu-Seb Mask vs. Eu-Seb Active Serum

Serum = daily microbiome-focused acne treatment. Mask = weekly intensive calming and rebalancing boost. MEDER recommends both together for best results; each can be used independently.
