Meder Beauty Eu-Seb Prebiotic Anti-Acne Active Serum

Acne-prone skin doesn’t need to be punished. It needs to be brought back into balance.

Eu-Seb is the targeted serum for breakouts, excess oil, congestion and enlarged-looking pores. The approach is different from traditional acne care: instead of trying to sterilise the skin, Eu-Seb works with the skin microbiome — supporting beneficial microorganisms while addressing the conditions associated with acne.

Think of it as: rebalance → regulate → calm → clear.

Who is it for?

Acne-prone skin • oily or congested skin • blackheads and whiteheads • enlarged-looking pores • hormonal and period-related breakouts • adult acne • menopausal acne • athlete’s acne • sensitive skin that also breaks out (no need to choose between the two) • pregnancy and breastfeeding (MEDER confirms Eu-Seb is suitable).

Key ingredients

Prebiotic Bioecolia® (alpha-glucan oligosaccharide) — feeds beneficial microorganisms and helps create conditions that are less favourable for acne-associated bacteria; supports microbiome balance rather than trying to sterilise the skin.

Noni Stem-Cell Culture Extract (Morinda citrifolia) — targets acne-associated bacterial activity and inflammation; helps reduce comedones (blackheads and whiteheads).

Maclura Bioflavonoids — provide a retinol-like action (no traditional retinol) helping regulate excess sebum production, reduce oiliness and refine the appearance of pores. MEDER reports measurable sebum reduction within approximately two weeks.

Note: Eu-Seb does not contain traditional retinol and can be used during pregnancy. It can technically be layered with retinol or AHAs, but the question to ask is whether your skin actually needs all of them.

How to use

Apply after your everyday Meder serum (Soin-Apax) and before your moisturiser. Apply to the whole face — not just as a spot treatment. Morning and evening consistently for 5–10 weeks.

Routine: Net-Apax → Soin-Apax → Eu-Seb → Eu-Skin or Equa-Derm → SPF

For intensive weekly support, add Eu-Seb Mask once or twice a week. Enzy-Peel can also be introduced when appropriate.
