celimax The Vita-A Retinol Shot Tightening Serum 30ml

A serum that feels like a concentrated dose — the 30 ml format says it all, a treatment you measure rather than pour. The firming promise is right there in the name, no beating around the bush. What comes next is for the formula to show.

Texture and actives — Retinol is the star ingredient of this serum from Korean brand celimax — a vitamin A derivative whose effects on skin renewal have been well documented for decades. The "Vita-A" range puts this ingredient front and centre, without burying it under unnecessary jargon. The 30 ml bottle suggests a concentration designed for precise use, not a texture to be diluted.

In your routine — This serum fits into an evening routine, after double cleansing and before moisturiser. A few drops are all you need — apply with care, patting rather than rubbing, to let the retinol work without friction. A gradual approach is generally recommended with this type of active: start with two to three evenings a week, then increase according to how your skin responds.

• Key active: retinol (vitamin A derivative), known to support cell renewal and skin firmness.
• Size: 30 ml — a treatment-sized format, suited to daily use over roughly one to two months.
• Brand: celimax, a Korean skincare lab specialising in targeted active ingredients.
• Store away from light and heat to keep the retinol stable.
• Best introduced gradually into your routine, especially if your skin is not used to vitamin A derivatives.
