Peptides vs. Retinol: Do You Need Both, and In What Order?

Yes, you can use peptides and retinol together, and for most skin they work better as a pair than as rivals. Use retinol at night on clean, dry skin, and follow it with a peptide moisturizer. At night, combine both.

That is what we do, but what follows is the why. Once you understand what each ingredient is actually doing, the combination of both begins to make sense, not just in an article,  but on your skin.

 

Peptides vs. Retinol: What's the Difference?

The short version: retinol pushes, peptides support.

Retinol is a form of vitamin A. It works by speeding up the turnover of surface skin cells, boosting collagen, evening tone, and softening fine lines over time. It is one of the most studied anti-aging ingredients available without a prescription, and it earns that reputation. However, there can be side effects. Dryness, peeling, redness, and a stretch of looking worse before you look better are all common while skin adjusts.

Peptides work through a quieter mechanism. We covered what they are and how they signal skin in our piece on peptides (Sean or Janine insert link), so we won't repeat it here. For this conversation, let’s talk tolerance and combining. Peptides are generally well tolerated, and most people can use them without irritation. They support the barrier, can be anti-inflammatory, and they don't come with an adjustment period.

So one ingredient transforms, and the other helps it hold up while it does.

 

Peptides vs. Retinol at a Glance

Can You Use Peptides and Retinol Together?

Yes, and this is one of the easiest ingredient pairings to get right. Retinoids can temporarily weaken the skin barrier while your skin adapts, and peptides help support barrier function during that window. 

They don't compete and don't cancel the other out. One eight-week study of 30 adults using a nightly product with low-dose retinol, a pea peptide, and antioxidants found measurable gains in hydration and elasticity with no reported irritation. Retinol does its work more comfortably when the skin around it is well supported.

If you have been told that peptides and retinol shouldn't be mixed, you may be thinking of copper peptides specifically. That caution circulates online, but it is largely theoretical, and in real routines the two tend to be far more compatible than older advice suggests.

 

What Order Do You Apply Peptides and Retinol?

Retinol first, peptides second.

Apply retinol to clean, dry skin so it has direct contact, then seal it in with your peptide moisturizer. When layering separate products, dermatologists generally recommend applying retinol on cleansed skin and following with the peptide moisturizer.If your skin runs sensitive, or you are in the early weeks and feeling it, try the sandwich method. Apply a thin layer of moisturizer, then your retinol, then moisturizer again. The first layer softens retinol's contact with the skin without blocking it entirely. It is a slower road, but consistency is what makes retinols work.

 

How Often Should You Use Peptides and Retinol?

Retinol: Start with the gentlest formula you can find and use it every other night, then slowly build from there. (Should I insert Lenox and 16th laser serum product here?) If every other night, so patience matters.

Peptides: Every day, morning and night. There is no ramp-up and no rest night required. This is the steady, background part of your routine that keeps working whether or not it's a retinol night.

That difference is actually the best argument for using both. Retinol does its heavy lifting a few nights a week. Peptides keep the foundation strong every single day, including the nights your skin is recovering.

 

Where Soft Landing Fits

Soft Landing was built to be the second half of this equation. It is a smoothing moisturizer powered by four classes of peptides (copper, Argireline, rice, and Matrixyl 3000) that work together to firm, smooth, and calm while supporting collagen. A dual-weight hyaluronic acid complex adds layered hydration, and resveratrol brings antioxidant protection.

It also contains bakuchiol, a plant-derived retinol alternative that refines texture and evens tone without the irritation. That matters for two different people. If you use retinol, bakuchiol is a gentle complement rather than a competitor. If you can't or don't want to use retinol, Soft Landing gives you a retinol-adjacent benefit on its own. Bakuchiol and retinol both significantly reduce wrinkle surface area and hyperpigmentation. One note worth knowing: none of the current Lenox and Sixteenth products contain retinol. So if retinol is part of your routine, it's coming from your own shelf, and Soft Landing is what goes on after. A soft landing, exactly as the name suggests.

 

A Simple Peptide and Retinol Routine

Morning

• Cleanse

• The Preservationist Vitamin C Cream Serum

• Soft Landing

• Broad-spectrum SPF 30 or higher (non-negotiable on a retinol routine)

Evening, retinol nights

• Cleanse gently and pat dry

• Retinol, a pea-sized amount for the whole face

• Soft Landing

Evening, Laser Serum nights

• Cleanse

• The Laser Serum

• Soft Landing

Keep retinol and The Laser Serum on separate nights. Stacking a retinoid and an acid exfoliant on the same evening is one of the fastest ways to irritate skin, and our own guidance for The Laser Serum is to avoid other actives like retinoids on the nights you use it. A good starting rhythm is retinol two or three nights a week, The Laser Serum on one or two others, and at least one night with nothing but cleanse and Soft Landing.

Peptides vs. retinol isn't really a choice. Retinol is the more aggressive change-maker, at night, a few times a week, introduced slowly. Peptides are the daily support system that keeps skin comfortable, resilient, and hydrated while retinol does its work. Use retinol first on clean skin, follow with a peptide moisturizer, wear SPF every morning, and let consistency do the rest.
