Subuji is a UK-based retailer specialising in authentic Korean Niacinamide 10% Serum UK skincare products shipped directly from Seoul. You’ll find a curated selection of serums from trusted brands, often featuring clear ingredient lists and original formulations. Because they source directly from Korea, you’re accessing the genuine Korean-market versions (not necessarily westernised versions) which often means stronger actives or better value.
What to look for: Niacinamide 10% and Hyaluronic Acid
Niacinamide 10% Serum UK is a great keyword to target because niacinamide at around 10% is a sweet spot for many skin types seeking brightening, pore-refining or tone-evening benefits without overly aggressive formulation. For example, one Korean serum lists niacinamide 10% together with tranexamic acid for dark-spot correction.
Hyaluronic acid is a cornerstone of hydration routines — look for multi-molecular-weight formulations, which deliver moisture at different levels of the skin. Subuji lists several such products.
How to pick the right serum on Subuji
-
Match your skin concern –
-
If you’re dealing with uneven skin tone, dark spots or enlarged pores: choose a serum that explicitly states “niacinamide 10%” or similar.
-
If your skin is dry, dehydrated or in need of bounce: opt for a hyaluronic-acid heavy serum.
-
-
Check the ingredients – Make sure the formula is suitable for your skin type, and that the percentage of niacinamide is clearly mentioned (10% is a sound target).
-
Check shipping and authenticity – Subuji provides clear shipping info (they ship from Seoul) which helps ensure authenticity.
-
Patch test & integrate slowly – Even though K-Beauty is known for gentle textures, active ingredients (high % niacinamide, acid blends, hyaluronic with stronger humectants) still warrant a patch test.

Routine Tips for Best Results
-
Morning: After cleanser and toner, apply your Niacinamide 10% serum, wait a minute for absorption, then follow with your moisturiser and SPF.
-
Evening: If you chose the hyaluronic acid serum, apply it after your toner/essence step and before a richer cream or oil if needed.
-
Combine carefully: If you’re using strong actives (e.g., acid exfoliants) and a high-percentage niacinamide serum, ensure your skin is well moisturised and not over-exposed.
-
Consistency matters: Results with niacinamide and hyaluronic acid generally appear over weeks rather than overnight—give it at least 4-6 weeks of consistent use.
