Learn the correct serum layering order for your skincare routine, from thinnest to thickest, and how to apply a serum concentrate without pilling.
Quick answer
Apply serums from thinnest to thickest consistency, then follow with moisturizer. Water-based formulas go first, followed by oil-based serums or concentrates. Wait 30–60 seconds between layers to let each absorb. This order prevents pilling and ensures active ingredients reach your skin.
Why the order of serums matters
Serums are concentrated formulas designed to deliver active ingredients. If you apply a thick oil before a water-based serum, the oil can block the lighter formula from penetrating. The general rule is to apply products from the thinnest texture to the thickest. This allows each layer to absorb without interference.
How to apply a serum concentrate
Serum concentrates, like Odacité's Radiance • Green Tea + Lemongrass • Gt+L Serum Concentrate, are highly potent and often oil-based. They are not meant to be applied like a standard serum. Instead, mix 2–3 drops into your moisturizer or apply as the last serum step before moisturizer. This prevents irritation and ensures even distribution.
Layering vitamin C and hyaluronic acid
Vitamin C serums are typically water-based and acidic, while hyaluronic acid serums are also water-based but work best on damp skin. Apply vitamin C first, wait 1–2 minutes, then apply hyaluronic acid. If your vitamin C is oil-based, apply it after water-based hyaluronic acid. Always follow with a moisturizer to seal in hydration.
Step-by-step serum layering order
- Start with clean, damp skin: After cleansing, leave skin slightly damp. This helps water-based serums absorb better and prevents them from drying out your skin. Mist with water or apply immediately after cleansing.
- Apply water-based serums first: Use any water-based serums, such as vitamin C or hyaluronic acid. Pat gently into skin and wait 30–60 seconds. Check consistency: if it's watery, it goes first.
- Follow with oil-based serums or concentrates: Apply oil-based serums or serum concentrates like Radiance • Green Tea + Lemongrass. Warm 2–3 drops between palms and press into skin. Oils go after water; never before.
- Lock in with moisturizer: Finish with a moisturizer like Cellular Infusion Cream • NAD+ Biomimetic Peptides to seal everything in and support your skin barrier. This step is non-negotiable, even for oily skin.
Products that fit this routine
- Cellular Infusion Cream • NAD+ Biomimetic Peptides: Cellular Infusion Cream • NAD+ Biomimetic Peptides is a next-generation moisturizer powered by BioStem8TM Longevity Complex. Use it as the final step to seal in serums and support skin's biological functions.
- Brightening Serum • Vitamin C & E + Hyaluronic Acid: Brightening Serum • Vitamin C & E + Hyaluronic Acid is a dark spot correcting serum with Advanced Encapsulation Technology. Apply this water-based serum early in your routine for visible brightening and fine line reduction.
- Radiance • Green Tea + Lemongrass • Gt+L Serum Concentrate: Radiance • Green Tea + Lemongrass • Gt+L Serum Concentrate is a silky, lightweight facial oil that delivers targeted actives in just a few drops. Because it's oil-based, apply it after water-based serums but before moisturizer.
