The right face serum is the one built around the ingredient that matches your main skin goal. Want softer, plumper-looking skin? Look for hyaluronic acid. Chasing brightness and a more even-looking tone? Vitamin C. Smoothing fine lines and signs of ageing? Retinol. This guide explains what a serum actually is, how to read the label, and which type suits hydration, brightening or anti-ageing — with five vegan Glimify serums matched to each goal.
The short answer: pick your serum by its hero ingredient
A serum is a lightweight, concentrated treatment you apply after cleansing (and toning) but before moisturiser. Because it is more concentrated than a moisturiser and made of smaller, faster-absorbing molecules, it is where you target a specific concern. So the smart way to choose is to name your priority first, then pick the serum whose hero ingredient is made for it. If you are new to all of this, our beginner skincare routine guide shows exactly where a serum sits in the running order.
Match the serum to your goal
For hydration and plumpness: hyaluronic acid
Hyaluronic acid is a hydration hero — it helps skin attract and hold on to water, so it looks plumper, softer and less tired. It suits every skin type, including oily skin that still needs water without heaviness. If you would like the full science, we cover it in hyaluronic acid explained. Glimify's Hyaluronic Acid Serum (£8.99) is the straightforward pick here, and the bestselling DewySKIN Infusion Glow Serum (£8.99) pairs hyaluronic acid with a dewy, brightening finish.
For brightness and even-looking tone: vitamin C (or turmeric)
If your skin looks dull or uneven, a brightening serum is the one to reach for. Vitamin C is the best known — it helps brighten the look of tired skin and support a more even-looking tone over time. Turmeric is a gentler, plant-led alternative with a similar brightening feel. Glimify's Vitamin C + Retinol Serum (£15.99) covers brightening and anti-ageing in one, while the Turmeric Face Serum (£9.99) is a lovely everyday brightener.
For fine lines and signs of ageing: retinol
Retinol is the go-to for a smoother, firmer-looking complexion and softening the appearance of fine lines. It is powerful, so introduce it slowly — a couple of nights a week to start — and always wear SPF the next morning, as retinol can make skin more sensitive to sunlight. Glimify's Vitamin C + Retinol Serum delivers retinol alongside brightening vitamin C, which makes it an easy first step into anti-ageing care.
How to choose a face serum, step by step
1. Name your one main goal
Serums reward focus. Pick the single concern that matters most right now — hydration, brightening or anti-ageing — and choose for that. You can always add a second serum later.
2. Check the hero ingredient and the label
The front of the bottle usually names the star ingredient; the ingredients list confirms it. Look for the actives above — hyaluronic acid, vitamin C, retinol, turmeric — and for the values that matter to you, such as vegan and cruelty-free. Every Glimify serum is both.
3. Think about texture and layering
Lightweight, water-based serums (like hyaluronic acid) sit well under any moisturiser and suit oily skin. If you use more than one serum, a simple rule is to apply the most water-like first and let each layer settle. Hydrating serums layer happily with almost anything; strong actives like retinol are best kept to the evening.
4. Fit it to your routine and be consistent
A serum goes on after cleansing and toning, before moisturiser. Give any active a few weeks of consistent use before judging it — brightening and anti-ageing results build gradually, not overnight.

Frequently asked questions
What does a face serum actually do?
A serum is a concentrated treatment step that targets a specific concern — hydration, brightness or ageing — with a higher dose of active ingredients than a moisturiser, in a lighter, faster-absorbing texture.
Can I use more than one serum?
Yes. A common approach is a hydrating serum in the morning and a treatment serum (like vitamin C or retinol) at another time. Apply the lightest texture first and keep retinol to the evening.
Do I still need a moisturiser if I use a serum?
Yes — a serum treats, a moisturiser seals in hydration and protects the skin barrier. Use the serum first, then moisturiser on top.
Which Glimify serum should a beginner start with?
A hyaluronic acid serum is the easiest starting point: it suits every skin type, layers with everything and simply boosts hydration. From there you can add a brightening or anti-ageing serum.
