To really let your hyaluronic acid serum shine, there are a few key rules worth knowing. Why? Because when used incorrectly, hyaluronic acid can do the opposite of what you want, leaving your skin feeling drier and more dehydrated than when you started. Here's how to avoid that.

1. You’re applying it to dry skin

This is a common one and a biggie. Hyaluronic acid is a humectant, meaning it pulls moisture from wherever it can find it. Ideally, that’s the air around you or the water on your skin. But if your face is dry when you apply it? It’ll draw moisture from your own skin, which defeats the purpose and can leave your complexion feeling tight or flaky.

What to do instead:

Always apply your hyaluronic serum to slightly damp skin. You don’t need to be dripping wet, a light mist or just-towel-dried skin is perfect.

2. You’re not layering it in the right order

Hyaluronic acid works best when it’s layered correctly in your routine. A general rule of thumb? Go from thinnest to thickest, and actives first, hydrators second.

That means if you're using treatments like retinol or exfoliating acids (BHAs or AHAs), apply those first. Then follow with your You Glow Girl Skin Drink to calm, soothe, and rehydrate.

Always check specific product instructions, but as a guide:

Actives → Hydrating Serums → Oils → Moisturiser

3. You’re not sealing it in

Here’s the thing: hyaluronic acid needs help staying put. If you leave it unsealed, it can evaporate — and take your skin’s moisture with it. Drama, right?

The fix? Lock it in with an oil, moisturiser, or both.

In the AM, follow with a moisturiser.

In the PM, apply a facial oil before layering on a rich moisturiser to fully seal in hydration.

Your skin will thank you… plumper, bouncier, and better hydrated!
