WINTER SERUM FAQ

Your winter hydration questions, answered

What's the difference between dry and dehydrated skin?

Dry skin lacks oil; dehydrated skin lacks water – and winter causes a lot of the latter, even in oily skin. A hydrating serum (usually hyaluronic-acid based) tackles dehydration by drawing water into the skin. If your skin feels tight but also gets shiny, you're likely dehydrated and this list is for you.

How do I use a hydrating serum in winter?

Apply to slightly damp skin – hyaluronic acid pulls in surrounding moisture, so damp skin gives it something to grab. Then always follow with a moisturiser or oil to seal it in. In dry, heated rooms, hyaluronic acid applied to dry skin can actually pull moisture out, so the damp-skin-then-seal step really matters.

Can I use a hydrating serum with retinol or vitamin C?

Yes – hydrating serums pair well with most actives and can buffer irritation. Apply your treatment serum first, then the hydrator, then moisturiser. In winter, layering a hydrating serum over an active often makes the active far more tolerable.

Which serum is best for sensitive skin?

Fitglow Birch Hyaluronic Quench + Calm (#5) and Wildcrafted Wild Pansy (#9) are our gentlest picks – both hydrate while actively soothing redness. Patch-test on the inner forearm for 24 hours before applying to the face.

Are all of these clean and cruelty-free?

Yes. Every brand we stock is independently reviewed: no synthetic fragrance, no drying alcohols, no hormone disruptors, and never tested on animals. Many are certified organic and several are made here in Australia.

How did you test these serums?

Our editors layered each serum under moisturiser daily for at least four weeks through July and August. We rated how fast skin felt quenched, plumpness, layering under makeup and comfort at eight hours, then cross-checked against verified customer reviews – only serums with a 4.5★ baseline made the cut.
