Serum Sticks 101: Hyaluronic Acid, Retinol and Niacinamide

A serum stick is a serum. Same active ingredient categories as our bottle serums, just suspended in a solid, twist-up balm base instead of a liquid. The Hyaluronic Acid 2%, Retinol 0.2% and Niacinamide 8% sticks are built to be swiped straight onto skin with no dropper, no basin, and no risk of tipping over in a bag. Reach for a stick when you need a fast, targeted top-up or you're not near a mirror and a full routine. Reach for the bottle when you're doing your whole face at home with the rest of your products layered in properly.

What's actually different about the stick format

Bottle serums are water-based, which is exactly what lets them absorb quickly and layer under a moisturiser. That water base is also why they need a cap that seals properly and why they're not doing anyone favours sitting in direct sun.

The sticks use an anhydrous balm base, oils and waxes rather than water, to carry the same active down onto skin in a solid form. Twist up, swipe, twist back down. Nothing to spill, nothing to leak through a side pocket, and the stick itself stays sealed between uses instead of being exposed to air every time you open it. That's a genuine practical difference, not just a format gimmick.

The three sticks, one by one

Hyaluronic Acid 2% Serum Stick (R185.00) visibly targets signs of dryness, promotes smoother looking skin, and visibly improves the look of skin's moisture barrier. Use it for quick on-the-go relief from visible dryness, or as an overnight treatment for full-face hydration. This is the one to keep in your bag if your skin gets tight or flaky by midday, especially with aircon or heating running indoors.

Retinol 0.2% Serum Stick (R185.00) is actual retinol, not the vegan retinoid we use in our moisturiser. It visibly smoothes skin texture and promotes a clearer, more even-toned complexion. Use it as a quick on-the-go pick me up, or as an overnight treatment for a full face. Because it's a low percentage in a solid, easy-to-control format, it's a reasonable way to introduce retinol without committing to a full liquid serum straight away, start with a few nights a week and build from there.

Niacinamide 8% Serum Stick (regular R185.00, currently R110.00) targets the visible appearance of pigmentation and dark marks and reduces the look of enlarged pores and excess oil. Use it on the go for a quick glow, or overnight for the full face. If you've read our piece on what niacinamide 10% actually does and it sounds like a lot to start with, the 8% stick is the gentler entry point, same ingredient category, lower dose, easier to test on your own skin first.

Stick vs bottle: when to reach for which

• Full nightly routine at home: bottle serum. You get more product per use and it layers properly with a moisturiser underneath everything else.
• Gym bag, car, or handbag: stick. Nothing to spill on your kit, nothing to leak into your bag, and no bottle rolling around loose.
• Post-workout, sweaty, no time for a full routine: stick. A quick swipe over the areas that need it beats skipping actives entirely.
• Sitting in a hot car for hours: stick. A sealed balm handles heat better than an open bottle of watery serum left in direct sun on a dashboard.
• Midday touch-up over makeup-free skin: stick, applied directly with clean fingers, no need to redo your whole face.

Why this matters more from now until summer

September through November is spring in South Africa, and by October the UV index is already climbing. That usually means more time outdoors, more gym sessions, more weekends away, and less patience for carrying a full skincare bag everywhere you go. A serum stick fits in a gym bag side pocket, a car cubby hole, or a carry-on without taking up the space or the worry a bottle does. If you're planning any warmer-weather travel over the next few months, this is the version of your routine that survives a holiday bag intact.

How to actually use them

1. Cleanse first if you're doing a proper application, we'd suggest the Oat Cleansing Gel for something gentle enough for daily use.
2. Twist the stick up until the balm is exposed, then swipe directly onto skin, either the full face or just the area you're targeting.
3. Give it 30 to 60 seconds to sink in before layering sunscreen or makeup over the top.
4. On the go, skip the cleanse step entirely, just swipe and blend in with a fingertip.
5. At night, all three can be used as leave-on treatments. If you're new to retinol, don't stack it with the niacinamide or HA stick on the same night until your skin has adjusted, alternate nights instead.

FAQ

Can I use more than one stick at the same time?

Hyaluronic acid pairs fine with either of the other two, it's a hydrating ingredient and won't compete with anything. Niacinamide and retinol can both go in the same routine once your skin is used to retinol, just introduce them one at a time rather than starting all three together.

Are the sticks strong enough to replace my bottle serum?

They can, if you're using them as an overnight full-face treatment rather than a quick swipe. The honest answer is that for most people they work best as a companion to the bottle serum, the bottle for your main routine and the stick for everywhere the bottle doesn't reach conveniently, gym bag, desk drawer, car.

Will a serum stick melt or spoil in a hot car?

The balm base is far more heat-stable than a water-based serum. It can soften slightly in extreme heat, which is normal for a balm, but it won't leak or spill the way a liquid serum would.

Which stick should I start with if I'm new to actives?

Hyaluronic acid is the safest starting point for any skin type, it's hydrating and won't cause irritation. If pigmentation or oiliness is your main concern, the niacinamide 8% stick is a gentler dose than our 10% serum. Save retinol for once you've got the other two settled into your routine.

Do I still need sunscreen if I use the retinol stick during the day?

Yes. That applies to any retinol product, stick or bottle. If you're using it during the day, sunscreen is not optional, especially heading into a South African summer.
