Great Skin INSTANT GLOW SERUM

MERIT Great Skin Instant Glow Serum is a bi-phase serum you shake before using — light enough to feel like an essence, but built on hyaluronic acid, niacinamide and cacao seed extract. It is aimed at skin that reads dry, dull or uneven in texture, and it absorbs fast enough to go under makeup.

What it actually does

• Hydrates immediately, evens out over time. MERIT splits the claim: plumping and hydration are the instant part, while calmer, brighter and more even-looking skin is the longer-term part.
• Hyaluronic acid works at depth. The brand says it reaches multiple layers of skin to hold onto moisture all day.
• Niacinamide handles brightness and texture, which is how MERIT explains the shift toward a smoother, glowing complexion.
• Cacao seed extract is the caffeine element. The brand describes it as a caffeine-rich antioxidant that encourages blood flow for a plumped effect.
• Leaves no residue. The weightless texture sinks in cleanly, which is why MERIT positions it as a makeup-prep step.
• Built to sit alongside The Minimalist (sold separately), though the brand confirms it works under any complexion product or on its own.
• Vegan, gluten-free and cruelty-free, as listed.

How to use

1. Shake well. It is a bi-phase formula, so the two layers need combining before each use.
2. Dose by skin type. MERIT's guidance: 3 pumps for dry skin, 2 for normal, and 1–2 for combination or oily.
3. Warm it in your hands, then press it in. This goes after cleansing and before moisturiser.
4. Layering with other actives? Apply it after your other serums — the brand positions it as the step that seals hydration in and works on texture over time.
5. Then makeup, if you wear it. It is designed to sit under a base, or to be worn alone.

Questions

Why do I have to shake it?

Because it is bi-phase — two phases that naturally sit apart in the bottle. Shaking brings them together so each pump dispenses the full formula.

Can I use it with my vitamin C or retinol?

Yes. MERIT's instruction is to apply it after your other active serums, where it helps lock hydration in and work on texture.

Do I still need a moisturiser?

Yes — this sits after cleansing and before moisturiser in the brand's own sequence. It can be worn on its own for glow, but it is not a replacement for a moisturising step.

How long does delivery take?
