Peptide serums go on clean, dry skin before moisturizer, in both your morning and evening routine. The main rule to remember: don't apply a peptide in the exact same step as a strong AHA/BHA exfoliant or a high-dose Vitamin C — give each its own moment. Beyond the face, Asterwood's peptide lineup extends to an eye treatment, a lip treatment, and a body cream, so “layering peptides” can mean more than just a facial serum step.
The Basic Rule: Peptides Go on Clean, Dry Skin Before Moisturizer
Regardless of which peptide product you're using, the order is the same — cleanse, apply peptide serum to dry skin, then moisturizer, finish with SPF if it's morning.
Peptide serums are lightweight and meant to absorb quickly, which means they belong early in your routine, right after cleansing and before anything heavier. Applying a peptide serum to damp skin isn't necessary the way it is for a pure humectant — a peptide's job is to reach skin cells and signal them, not to grab water molecules, so clean and dry is the standard instruction across the Asterwood peptide lineup.
Morning Routine: Peptides Plus Sun Protection
A morning peptide routine is cleanser, peptide serum, moisturizer, then SPF — non-negotiable, since sun protection is the single most important anti-aging step regardless of what peptide you're using underneath it.
- Cleanse with the Barrier Boost Gel Cleanser or Hyaluronic Acid Cleansing Face Bar
- Apply your peptide serum of choice — Copper Peptides Serum, Matrixyl 3000 + Argireline Serum, Argireline Serum, or Triple Repair Serum — to clean, dry skin
- Follow with the Hyaluronic Acid Eye Serum around the eye area
- Moisturize, then finish with a broad-spectrum SPF 30 or higher — sunscreen is non-negotiable, whatever peptide serum you used underneath it
Evening Routine: Peptides Plus Repair
At night, the same peptide serum step gets followed by a richer cream instead of SPF, since overnight is when skin does most of its repair work, with no UV exposure to plan around.
- Cleanse, then optionally apply the Dual Phase Milky Toner as an early-routine prep step (shake well first — it's a dual-phase formula; contains milk protein, so skip it if you have a dairy allergy)
- Apply your peptide serum to clean, dry skin — same options as the morning list
- Layer the Hyaluronic Acid Eye Serum if you didn't already use it in the morning
- Finish with the Triple Repair Cream or the Copper Peptides Booster Cream, depending on which serum you used — pairing the cream with the same peptide family keeps the routine simple
What Never Goes in the Same Step as a Peptide
Keep peptides out of the same application step as a strong AHA/BHA exfoliant or high-dose Vitamin C — not because the ingredients are unsafe together, but because the pH swing between them can reduce how well each one performs.
If your routine includes the Overnight AHA+BHA Exfoliating Serum, use it on separate nights from your peptide serum rather than the same evening. If you're using a high-dose Vitamin C step, put it in a different part of your routine than your peptide — Asterwood's Triple Repair line handles this by using a lower, gentler, stabilized form of Vitamin C specifically so it can coexist with peptides in one formula, but a standalone high-percentage Vitamin C serum deserves its own step.
Layering Peptides Beyond the Face
“Peptide routine” doesn't have to stop at your jawline — lips, the eye area, and body skin all have their own peptide-formulated options, and they slot into your routine at different points than your facial serum does.
For lips, apply the Volulip™ Plumping Lip Treatment as its own step, any time of day, since it's a standalone treatment rather than part of the cleanse-serum-moisturize sequence. For the body, the Power Peptide Firming Body Cream works best applied right after showering, while skin is still slightly damp — this is specifically called out in the product's own directions, since damp skin helps lock in hydration and boosts absorption of the peptides and ceramides inside it.
If Your Skin Is Oily, Combination, or Acne-Prone
The layering order stays the same, but swap a rich cream for a lighter one — the Peptide Barrier Gel Cream follows any peptide serum with a lightweight, fast-absorbing gel-cream base instead of a heavier moisturizer.
A Sample 7-Day Peptide Routine to Start With
If you're starting from zero, a simple week-one routine is one peptide serum, once a day, before you add anything else — here's what that looks like in practice.
- Days 1-3 (AM only): cleanse, peptide serum of choice, moisturizer, SPF
- Days 4-7 (AM and PM): add the same peptide serum to your evening routine, followed by a moisturizer or the matching peptide cream
- Week 2 onward: layer in the Hyaluronic Acid Eye Serum and, if relevant, the Volulip Lip Treatment or Power Peptide Firming Body Cream, one at a time
- Ongoing: reassess after 4-8 weeks — that's typically when firmness or expression-line softening becomes noticeable enough to evaluate whether to add a second peptide product
This slower build isn't a strict requirement — peptides are one of the more tolerable categories of active ingredients — but it's the easiest way to notice what's working, especially if you're also introducing other new products around the same time.
Introducing a New Peptide Product? Start Slow
Add one new peptide product at a time rather than overhauling your whole routine at once, so you can actually tell what's working and give your skin time to adjust.
Most Asterwood peptide products are gentle enough for daily AM and PM use from the start, but if you're combining a new peptide serum with other actives already in your routine, patch test first and give it a week or two before adding anything else new. This isn't a strict rule so much as good practice — peptides are one of the more tolerable categories of actives, but “tolerable” isn't the same as “impossible to overdo.”
Traveling or Simplifying? A Minimalist 2-Product Peptide Routine
If you want the simplest possible peptide routine — for travel, or just to cut down on steps — one peptide serum plus one moisturizer covers the essentials without leaving out what matters most.
Pick a single serum based on your main concern (Copper Peptides Serum for firmness, Argireline Serum for expression lines, or the Matrixyl 3000 + Argireline Serum if you want both covered in one bottle), apply it to clean, dry skin, and follow with any moisturizer you already have on hand. Add SPF in the morning and you have a complete, effective routine in two steps. Everything else in this guide — the eye serum, the lip treatment, the body cream, the toner — is additive, not required, and can wait until you're back to your full routine.
