DIY Serum Guides
Everything you need to formulate your own active-packed serum at home — from the basics of mixing, to which ingredients pair beautifully together.
The Basics of Layering Serums
Every one of our serums is concentrated enough to apply directly to cleansed skin — 2–4 drops is usually plenty. Prefer a lighter touch? You can also mix a few drops into your regular moisturiser instead.
As a general rule, apply your lightest, most water-based formulas first (like Niacinamide HA Serum or Glass Skin Glow Serum), then layer richer, more concentrated serums on top (like BNX-APH5 Lifting Serum or PDRN Collagen Serum), finishing with your moisturiser to seal everything in. Want an extra boost? Dissolve a vial of Collagen Powder Vial into any serum before applying.
Always patch test a new active on your inner arm for 24–48 hours before applying it to your face, and introduce one new ingredient at a time so you know exactly what's working (or not).
Which Actives Play Well Together
Great pairings
- Niacinamide HA Serum + BNX-APH5 Lifting Serum — hydration and visible firmness
- Centella Calming Serum + Amino Barrier Exosome Serum — calming, barrier-supportive duo
- PDRN Collagen Serum + Niacinamide HA Serum — a hydrating base that helps PDRN Collagen glide on
- Glass Skin Glow Serum + Amino Barrier Exosome Serum — deeper, longer-lasting hydration
Better in separate routines
- Glass Skin Glow Serum + BNX-APH5 Lifting Serum, Niacinamide HA Serum, Centella Calming Serum or PDRN Collagen Serum — the Glutathione in Glass Skin Glow can be degraded by the Copper Tripeptide-1 in these formulas when layered together
This isn't a skin-safety issue — it just means both actives work less effectively when combined, so we'd suggest alternating them (e.g. AM/PM, or different days) rather than layering.
