Face serums

A serum is the treatment step in a routine. It carries a higher share of active ingredients in a light base that sinks in fast, so it goes on after cleansing and before your moisturiser. A serum treats, a cream seals. That is the practical difference between them, and it is why a serum belongs early in your facial skincare routine instead of replacing your moisturiser.

The actives, and the concern each one answers

Most serums are built around one lead ingredient. Pick that ingredient by your main concern, not by the label design.

• Vitamin C: an antioxidant, used in the morning for a brighter, more even looking tone. It breaks down in light and air, so opaque or airtight packaging is a genuine buying criterion.
• Niacinamide (vitamin B3): suits oily and congested skin. Four to ten percent is the usual range. Higher is not better and often stings.
• Hyaluronic acid: holds water in the upper skin layers. Apply it to damp skin and seal it with a cream, otherwise it can feel tight in dry indoor air. See our hyaluronic acid selection.
• Retinol and retinal: vitamin A forms for fine lines and rough texture. Evening only, two nights a week to start.
• Peptides and ceramides: the calmer route when acids and retinoids leave your skin reactive.

Texture decides whether layering works

Two serums can hold the same active and behave differently. Watery gels absorb in seconds. Silicone or oil rich formulas sit on top and can pill, those little rolls of product under your fingers. Work from thin to thick, give each layer half a minute, and keep nourishing facial oils for the very end, because oil blocks a water based serum applied over it.

How we choose the serums in this collection

We judge three things: the form of the active, the concentration, and whether the combination in one bottle makes sense. Vitamin C in light protective packaging. Niacinamide in the range skin actually tolerates. Retinal for people who want more than retinol. We leave out bottles that stack several strong acids with a retinoid, because that mostly buys irritation. We buy directly from the brands, so what arrives is authentic, and every product passes our compliance team before it goes live. You can read how we select brands.

What a serum can and cannot do

Be realistic about timing. A hydrating serum makes skin look plumper the same day. Vitamin C usually needs two to four weeks of daily use before tone looks more even, and retinol or retinal often need eight to twelve weeks. Stopping after ten days tells you nothing.

A serum also has a ceiling. Daily sunscreen protects the result you are paying for, especially with vitamin A forms, which make skin more sensitive to sunlight. If your skin is easily irritated, one serum plus a moisturiser will take you further than four bottles used inconsistently. Start with the single concern that bothers you most, keep it up for six weeks, then decide whether to add anything.
