Patch. Serum. Mask.
Glass skin.

Three formulas, the doses printed on the box, and a ritual that fits a real week: patches in the morning, serum every day, mask two evenings. That's the whole brand.

0.5% GHK‑Cu, 3% niacinamide. If it's on the box, it's in the serum — and you can check the full list on every page.

02

Blue because it's copper.

Copper Serum is pale blue for one reason: the copper peptide inside. No dye, nothing to hide — the colour is the ingredient.

03

A ritual, not a shelf.

Patches every morning, serum every day, masks two evenings a week. One month, one Trio, nothing to figure out.

    What we don't say

    No "anti-ageing" promises, no "clinically proven" without the study, no "free from" lists. Cosmetic claims in the EU must be substantiated and fair, so we describe how skin looks and feels, and we show the ingredients. If a test is added, we publish it here.

    Glass Mask sheet coming out of its sachet
    About

    Two products. Printed doses. Nothing to hide.

    Seoulence started with a simple frustration: peptide skincare where you never know how much peptide you're actually getting. So we made two products, put the concentrations on the box, and stopped there.

    Glass Mask is a sheet mask with 0.5% copper peptide and 3% niacinamide in 25 g of serum. Copper Serum is the daily step — pale blue, because that's what copper peptide looks like. Moon Patch is a pair of hydrogel crescents with caffeine and centella, sealed one pair at a time. Together they make a ritual that fits a real week.

    [Origin and manufacturing paragraph — to write once the manufacturer and country of origin are confirmed. Do not publish "Korean" origin claims before confirmation.]

    [Founders paragraph — optional.]

    Questions, answered.

    Using the products

    How often should I use the Glass Mask?
    Two to three times a week in the evening. One box of 5 lasts about two weeks at that pace — which is why the 3-box routine is the most popular.
    Can I use the Moon Patch every day?
    Yes. One pair in the morning for 15–20 minutes, before make-up. A box of 30 pairs is one month.
    How do I use the Copper Serum?
    Three drops on clean, slightly damp skin, morning and evening, before moisturiser. It's pale blue because of the copper peptide — that's normal, and it disappears as it absorbs.
    Can I use everything at the same time?
    Yes — that's the Trio ritual. Serum first, then patches under the eyes, then the mask over the top on mask nights.
    Is it suitable for sensitive skin?
    As with any new product, patch-test on your inner arm first and stop if irritation occurs. [Tolerance test result to add.]
    Can I use it during pregnancy?
    We don't make medical recommendations. Please check the ingredient list with your doctor or midwife.
    Where is it made?
    [To complete once the manufacturer's origin is confirmed. The country of origin will also appear on the packaging.]

    4. Behaviour to replicate

    • Sticky add-to-cart bar on mobile when the main button scrolls out of view.
    • Two announcement bars: scrolling marquee (offers) + rotating single line (thresholds, club, new).
    • Cart drawer opens on add; shows threshold bar, line items with qty, cross-sell, free gift line when ≥ €70.
    • Product switch pills on PDP link to the other products.
    • Quiz result adds the recommended variant directly to cart.

    5. Compliance checklist (blocking before go-live)

    • Legal entity: Novem Quay Limited (Hong Kong, BRN 81372208) — already filled in legal pages. It cannot be the EU Responsible Person: appoint one and add its name + address on site (contact + legal) and packs.
    • GDPR art. 27 EU representative to appoint (non‑EU controller selling to EU consumers); EU VAT / OSS‑IOSS registration before first sale.
    • CPNP notification done; CPSR signed; country of origin on packs (mandatory for non-EU manufacture).
    • No "free from" claims anywhere (parabens, mineral oil, colour). Already removed from this mockup.
    • "Dermatologically tested" only with a test report; before/after copy limited to looks/feels.
    • INCI lists match the manufacturer's final formula and order.
    • Influencer content carries "publicité" / "collaboration commerciale" (loi 2023‑451) and filter disclosure.
    • Withdrawal exception for unsealed hygiene products stated in CGV and at checkout.
    • Cosmetovigilance email live; undesirable-effect reporting path in contact form.

    6. Assets

    Packshots and brand boards are in the shared folder (Seoulence_01 → 08). Export webp 2048 px for PDP, 1200 px for cards, 9:16 for video covers. Fonts: Sofia Pro Soft (headlines), Aktiv Grotesk (body), Source Han Sans KR (Korean) — Adobe Fonts licence needed for web; fallback pairing used here: Outfit / Hanken Grotesk / Noto Sans KR.

    7. Open items

    • Brand name: Seoulence in this mockup; may change to Seouluna — keep the name in one theme setting / metafield.
    • Country of origin and manufacturer: pending supplier confirmation.
    • EU Responsible Person, GDPR EU representative, EU VAT/OSS: to appoint / obtain.
    • Moon Patch GHK‑Cu % and Glass Mask INCI order: pending certificate of analysis.
