Guide

How to layer a serum and moisturizer

Last updated

The rule is short and the reasoning behind it is worth understanding, because it tells you when the rule matters and when it does not.

The order

  1. Cleanse.
  2. Apply serum to clean skin.
  3. Wait until it has absorbed.
  4. Apply moisturizer.
  5. In the morning, finish with sunscreen.

Amplified Glow's own directions follow this. Its serums are directed for application to clean skin followed by moisturizer; its creams are directed for use alone or after a serum has absorbed.

Why lighter goes first

A cream leaves a more substantial layer on the skin surface, containing lipids that help limit water loss. Applying a lighter, water-based serum on top of that layer means the serum has to get through it.

The other way round, the serum goes onto clean skin and the cream follows, which also helps hold humectant ingredients in place — relevant for serums built around sodium hyaluronate, which is most of them. Our sodium hyaluronate page covers why a humectant benefits from something over the top.

How long to wait

Until the serum no longer feels wet. For most lightweight serums that is well under a minute.

Precise waiting times circulate widely and are mostly folklore. Amplified Glow does not specify one, and neither will we. Absorbed is the condition; the clock is not.

Applying this to the Amplified Glow range

The GHK-Cu + SNAP-8 serum and the GHK-Cu + SNAP-8 cream are designed as a pair — matching peptide disclosures, shared botanical blend, directions written for layering. The Copper Peptide Renewal Serum and Copper Peptide Renewal Cream pair the same way, both disclosing 0.1% GHK-Cu.

What Amplified Glow does not address is layering products from different lines, or combining its vitamin C serum with a peptide serum. We have not invented guidance for that — see vitamin C and copper peptide routine considerations.

Frequently asked questions

Serum or moisturizer first?

Serum first, then moisturizer.

How long should I wait between them?

Until the serum has absorbed and no longer feels wet. Usually under a minute. Specific timings you see quoted are not based on much.

Can I mix them in my hand to save a step?

You can, and people do. It changes what each product is doing — you are creating a diluted blend rather than two layers. It is not dangerous; it just is not how either is designed to be used.

Does sunscreen go before or after moisturizer?

After. Sunscreen is the last step of a morning routine.

GHK-Cu + SNAP-8 Peptide Renewal Serum

This is the best-documented serum in the Amplified Glow range. It is the only skincare product in the catalogue that publishes a copper peptide percentage, names three separate peptides, and states a fragrance-free formulation — three things a shopper can actually check before buying. At 30 mL for $21 it is the smallest serum Amplified Glow sells and the most expensive per millilitre. The full ingredient list is not published as text anywhere we could find, so anyone screening for a specific ingredient still cannot do so from the website alone.

GHK-Cu + SNAP-8 Copper Peptide Cream

This is the largest and best-value moisturizer in the Amplified Glow range: 50 mL for $20.00, or $40.00 per 100 mL, against $80.00 per 100 mL for the 30 mL Copper Peptide Renewal Cream. The trade-off is disclosure. The Renewal Cream publishes a 0.1% GHK-Cu figure; this one publishes no copper peptide percentage at all, despite naming the peptide in the product title.

Copper Peptide Renewal Cream

This 30 mL cream is the only Amplified Glow moisturizer that publishes a copper peptide percentage — 0.1% GHK-Cu — and the only one whose disclosed hero ingredients are led by richer emollients: shea butter, jojoba oil and pomegranate seed oil. It is also the most expensive moisturizer per millilitre in the range at $80.00 per 100 mL. If the disclosed percentage matters to you, this is the cream that has one; if volume for money matters more, the 50 mL GHK-Cu + SNAP-8 cream is half the price per millilitre.

Serum vs Cream: Choosing a Format

If you already use a moisturizer you are happy with, buy the serum — it adds the peptide step without replacing anything. If you do not currently use a moisturizer, buy the cream, because a serum is not designed to be the last leave-on step. On price, the creams give more product per dollar in this range: the 50 mL GHK-Cu + SNAP-8 cream is $40.00 per 100 mL against $70.00 for the 30 mL serum.

GHK-Cu

GHK-Cu is a small peptide complexed with copper. In cosmetics it appears under the INCI name Copper Tripeptide-1 and is used as a conditioning ingredient.
