Confused about what order to apply your skincare products?
You're not alone.
Most of us have stood in front of the bathroom mirror wondering if that fancy new serum goes before or after moisturizer.
The good news? Once you understand a few basic principles, layering your skincare becomes super simple.
Sure, you could just slather everything on and hope for the best, but taking a few minutes to learn the right order can make your products work so much better.
Think about it - if you're spending money on good skincare (like that Stratia C+C serum I’m always raving about), you want to make sure it's actually doing its job, right?

Using products in the wrong order is like putting your socks on after your shoes. It just doesn't work.
In this guide, I'll walk you through exactly how to layer your skincare products, which ones play nicely together, and which ones need their own space in your routine.
The Science Behind Product Layering
You don't need a chemistry degree like me to understand skincare, but knowing a few basics will make your routine work better.
Let's break it down super simply.
Water and Oil Don't Mix
Remember that science experiment in school where you tried mixing water and oil?
They separated, right?
The same thing happens with your skincare products.
Some are water-based (like most toners and serums) while others are oil-based (like face oils and some moisturizers).
Water-based products need to go first. Why?
Because oil blocks water - just like an umbrella blocks rain.
If you put your water-based vitamin C serum on top of a face oil, it won't be able to get through to your skin.
Size Matters
Skincare ingredients come in different sizes (stay with me here - this is actually pretty cool).
Imagine trying to push a basketball through a tennis net versus a tennis ball.
The tennis ball goes through easily, while the basketball gets stuck.
Your skin works the same way.
Lighter, smaller ingredients can sink in easily, while bigger molecules sit on top of your skin.
That's why we usually start with lightweight products and end with thicker ones.
pH Levels (Don't Worry, This Is Simple Too)
Some products, like certain exfoliants and vitamin C, work best at specific pH levels.
When you layer products with very different pH levels right after each other, they might not work as well as they should.
The easy fix?
Just wait a few minutes between layers.
Basic Rules of Layering
Let's get into the actual rules of layering your products.
Don't worry - there aren't many, and they're pretty easy to remember.
Rule #1: Thinnest to Thickest
Start with your most watery products and work your way up to the thick, creamy ones.
Here's what that usually looks like:
Watery toners go first
Lightweight serums come next
Thicker treatments after that
Creamy moisturizers
Oils last (if you use them)

For example, if you're using the Paula's Choice 2% BHA (which is super watery), it should go on before something thick like Mirror Skin’s Peptide Moisturizer.

Rule #2: Wait Times Matter (But Not As Much As You Think)
You don't need to stand around timing yourself between products.
Just follow these simple guidelines:
Let each layer sink in until it feels "almost dry" before adding the next
Give active ingredients like retinol or tretinoin about 2-3 minutes to settle
Sunscreen needs about a minute to form an even layer
Rule #3: Active Ingredients First
Products with active ingredients (like vitamin C, retinol, or exfoliants) work best when they can get directly to your skin.
Put these on after cleansing, when your skin is clean and ready to absorb them.
If you’re using multiple products with actives, apply the active ingredient that treats the problem you’re most concerned about first.
For example, I always apply tretinoin before copper peptides.
Product Categories and Their Order
Let's walk through each type of skincare product and exactly where it belongs in your routine.
Cleansers
Always start with clean skin. In the morning, a gentle cleanser like CeraVe Hydrating Cleanser or Prequel’s Glycerin Cleanser works great.
At night, you might want something that works harder to remove sunscreen and makeup - that's when a double cleanse can help.
Try starting with Tatcha’s Camelia Cleansing Oil followed by your regular cleanser.
Toners & Essences
These watery products go on right after cleansing.
But here's the thing - you don't actually need a toner.
If you like using one, great!
Just make sure it's not drying out your skin.
The Laneige Cream Skin Toner is a good option if you want extra hydration.

Active Treatments & Serums
This is where things get interesting. Here's how to layer different actives:
Morning:
Vitamin C serum (like Medik8’s C-Tetra) for antioxidant protection
Hydrating serums like DermElect’s Hydrating Serum if your skin needs extra moisture
Evening:
Exfoliating treatments (like Allies of Skin Mandelic Pigment Corrector) or retinoids (like Medik8’s Crystal Retinal)
Heads up, be careful if layering retinoids and exfoliants together. Not everyone can tolerate this.
If you're using tretinoin, that goes here too (and consider skipping other actives on tretinoin nights)
Moisturizer
Everyone needs moisturizer, even if you have oily skin.
In the morning, something light like CosRx Aqua Gel Cream works great.

At night, you might want something richer like Medik8’s Advanced Ceramide Night Cream, especially if you're using active ingredients.
Sunscreen (Morning Only)
Last step in your morning routine.
EltaMD UV Clear SPF 46 and Supergoop’s Zinc Screen are both great options that work under makeup.

Face Oils (Usually Evening)
If you use a facial oil like Stratia Fortify, it goes last at night to seal everything in.
Some people like using oils in the morning too, but I don’t typically them in the morning.
Let's move on to "Common Layering Mistakes" then:
Common Layering Mistakes
Doing Too Much at Once
Listen, I get it.
When you're excited about skincare, you want to try everything.
But using too many active ingredients at once is a recipe for irritated skin. Stick to one or two actives per routine.
You don't need vitamin C, niacinamide, AHA, AND retinol all at the same time.
Not Giving Products Time to Work
Rushing through your routine and piling products on top of each other right away?
That's probably why they're pilling (those annoying little balls that form on your skin).
Let each layer settle for a few seconds before adding the next one.
Mixing the Wrong Ingredients
Some things just don't play well together.
For example, using vitamin C and retinol at the same time can make both less effective.
Same goes for mixing tretinoin with harsh exfoliants - your skin won't thank you for that combo.
Using Oils Before Moisturizer
Oils can block other products from absorbing.
That's why they go last in your routine, not before your moisturizer.
The only exception is if you're doing the "oil sandwich" method for super dry skin.
Troubleshooting Your Layered Routine
If Your Products Are Pilling
When your skincare starts forming little balls on your skin, that's pilling. Usually happens because:
You're using too much product (a pea-sized amount is enough for most things)
You're not letting each layer dry enough
Your products might not get along (usually happens with silicone-based products)
Fix: Try using less product and waiting longer between layers. If that doesn't work, try using these products at different times of day instead.
If Your Skin Feels Irritated
Red, stinging skin? That's your skin barrier telling you to slow down.
Common causes:
Too many active ingredients
Using retinol or tretinoin too often
Not enough moisturizer
Mixing products that shouldn't go together
Fix: Strip your routine back to just cleanser, moisturizer, and SPF for a few days. Once your skin calms down, slowly add products back one at a time.
If Products Don't Seem to Work
Sometimes it feels like your products aren't doing anything. Usually this means:
You're not applying them in the right order
You're using too many products and they're canceling each other out
You haven't given them enough time to work
Fix: Stick to a simple routine for at least a month before deciding if something works. And remember - even the fanciest product won't work if it can't get to your skin because you're layering it wrong.
When to Start Over
If your current routine is just not working, don't be afraid to start fresh.
Go back to basics with just cleanser, moisturizer, and SPF.
Then add one product at a time, waiting a week between additions.
Sometimes less really is more when it comes to skincare.
In Conclusion: Keep it Simple
Remember when we talked about standing confused in front of the mirror?
Now you know exactly what goes where in your skincare routine.
The key is keeping it simple - you don't need a million products to have great skin.
Start with the basics:
Cleanser to clean your skin
Treatment for your specific skin concerns
Moisturizer to hydrate
SPF to protect (in the morning)
Once you've got that down, you can start experimenting with more products.
Just add them one at a time and pay attention to how your skin reacts.
And if you ever forget the right order? Just remember:
Thin products before thick ones
Active ingredients need to touch your skin to work
Sunscreen goes last in the morning
When in doubt, wait a minute between layers
Your skincare routine should work for you, not stress you out.
If something isn't working, it's okay to skip it or try something else.
The best routine is the one you'll actually stick to.
Cheers,
