Cleanser vs Moisturizer — Which Is More Important?

by Ella Goodman 06 Nov 2023

Hey there, skincare aficionados!

So, you've been bombarded with the age-old debate: cleanser versus moisturizer — which is the VIP in the grand ball of skincare?

The truth is, it's like asking whether you should drink water or eat food. Both are pretty darn crucial, right?

But let’s get down to the nitty-gritty and talk about why each one deserves a trophy in its own right.

Which Is More Important: Moisturizer or Cleanser?

Cleanser: The Unseen Hero

First up, let’s talk about what a cleanser really does.

On the surface (pun intended), its mission is to clear out the daily accumulation of gunk – we're talking makeup, sunscreen, sebum (that’s your skin’s natural oil), and environmental pollutants like exhaust fumes that stick to your face like bees to honey.

But what’s happening on a microscopic level is nothing short of a skincare Marvel movie.

When you massage that cleanser into your skin, you’re not just wiping away the day. You’re actually emulsifying these oils and impurities, making them mix with water so they can be rinsed away.

A great cleanser has a bit of a Goldilocks complex: it needs to be tough enough to tackle oil and makeup but gentle enough not to strip away your skin's natural protective barrier. This barrier, made of lipids, keeps the good stuff in (like moisture) and the bad stuff out (like irritants).

If your cleanser is too harsh, it's like a wildfire tearing through that protective barrier, leading to inflammation, dryness, and sensitivity.

If it’s too weak, it's like a security guard asleep on the job, letting all kinds of unwanted impurities throw a party on your face. For oily skin types, something with salicylic acid can dive into those pores and help keep acne at bay. Drier skin types might lean towards creamy, hydrating cleansers that whisper sweet nothings to their skin while they clean.

But the real secret sauce? Understanding pH levels.

Your skin is naturally a bit acidic, sitting pretty at around 5.5 on the pH scale. A good cleanser should respect that, keeping the peace and not sending your skin's pH into a tailspin.

Moisturizer: The Silent Guardian

Moving on to moisturizers, we’re not just talking about slapping on any old cream.

A top-notch moisturizer doesn't just sit on your skin like a lazy cat in the sun. It gets to work.

Hydrating ingredients like hyaluronic acid act like microscopic sponges, pulling water into the outer layer of your skin from the deeper layers and even the air.

Occlusives like petrolatum, if you’re into that, go full Gandalf, creating a barrier and proclaiming, "You shall not pass!" to water loss.

Then there are emollients—think of them as the skin’s personal landscapers, smoothing out the rough patches for a velvety finish.

Let’s chat science for a sec.

Your skin has this nifty thing called the Natural Moisturizing Factor (NMF), which is basically a mix of ingredients that your skin naturally produces to keep itself hydrated.

A good moisturizer boosts your skin's NMF, especially as age or environmental factors chip away at it.

And then there’s the anti-aging brigade.

Moisturizers with ingredients like retinol, collagen peptides, and antioxidants aren’t just hydrating – they’re fighting the good fight against time. They help to speed up cell turnover, boost collagen production, and fend off the free radicals from UV exposure and pollution that accelerate aging.

So, the drumroll, please...

Which is more important? It's like asking if you need the right partner or the perfect job to be happy.

Both, folks, both!

Cleanser and moisturizer work together like Sherlock and Watson – they’re just much better as a team.

Do You Need Both Cleanser and Moisturizer?

In a word? Absolutely. You can't have Ying without Yang, right?

Picture your skin as a bustling city.

Now, every city needs a good clean-up crew to keep the streets pristine, right? That's your cleanser. It sweeps through the avenues of your pores, collecting and disposing of the daily grime and leftover make-up, akin to the confetti after a New Year's bash.

And just as a city wouldn't thrive with trash lining its sidewalks, your skin won't glow if it's covered in an invisible film of pollutants.

Now, imagine that after the clean-up, there's no maintenance plan. The city's infrastructure would suffer, and the same goes for your skin.

Enter moisturizer, the city planner of skincare, ensuring everything runs smoothly after the initial cleanse. It's the crucial step that replenishes your skin's hydration reserves and keeps its protective barrier robust, just like a well-maintained city keeps its defenses against the elements strong.

But let’s dive into the "why" with a little skincare science.

When you cleanse, you’re also, inevitably, stripping away some natural oils and moisture along with the dirt and oil. It’s a necessary evil.

Your skin might feel squeaky clean, but without the follow-up of a moisturizer, it's also left more vulnerable to the elements, kind of like a castle without its moat.

This is where the moisturizer, laden with emollients and humectants, comes in to play the hero.

It works to repair and strengthen your skin's lipid barrier, which is essentially the security system that keeps the bad stuff out and the good stuff in.

Think of it like this: moisturizer seals in moisture and repairs your skin's barrier, like patching up the city walls after a day of defense.

But wait, there's more!

Your skin isn't just a static shield; it's a living, breathing organ that’s constantly in flux. It's dealing with internal factors like hormonal changes and external assaults from UV rays and pollution.

The moisturizer you use isn't just a superficial top coat; it's a supportive buddy that says, "Hey, I got you," offering antioxidants to fend off environmental stressors and ingredients like hyaluronic acid to bind moisture to the skin, ensuring it stays as hydrated as a tropical rainforest.

And let's not forget about the special agents in moisturizers tailored to specific skin concerns.

Got acne? There are moisturizers with niacinamide that help regulate oil production. Worried about wrinkles? Hello, moisturizers with peptides and ceramides that cheer on your skin's firmness and elasticity.

So, do you need both cleanser and moisturizer?

If you want your skin to be the city that never sleeps (but still looks like it got a full 8 hours), then the answer is a resounding yes.

Just as the best cities have a balance of clean streets and thriving public spaces, your skin deserves the balanced tag-team of a killer cleanser and a mighty moisturizer.

Can I Use Cleanser Without Moisturizer?

Technically, you can go cleanse-only and skip moisturizer, but it's a bit like walking a tightrope without a net — risky business!

Here’s the lowdown on why moisturizer should be your BFF after every cleanse.

When you wash your face, you're embarking on a necessary but delicate mission to remove unwanted guests from your skin's surface. Cleansers are the ninjas of skincare; they sneak in, battle the day's accumulation of oils, makeup, and pollutants, and then beat a swift retreat.

But, just like a ninja's path, sometimes there’s collateral damage. In this case, it’s your skin’s natural moisture and oils. The aftermath can leave your skin as barren as a deserted island.

Here’s the science of it all.

Your skin has this fabulous feature called the acid mantle — a very fine, slightly acidic film on the surface of the skin acting as a barrier to bacteria, viruses, and other potential contaminants. When you cleanse, especially with foaming agents or harsher detergents, you're potentially disrupting this protective mantle, leaving your skin vulnerable, almost like a knight without armor.

But wait — there’s more (again)!

Post-cleansing, your skin goes through a bit of an identity crisis. It starts thinking, “Hold on, where did all that lovely moisture go?”

If you don’t follow up with a moisturizer, your skin might just throw a hissy fit. This could mean cranking up oil production to overcompensate for the dryness, leading to an oilier complexion or, in a cruel twist of fate, breakouts.

Imagine your skin is a parched plant. You wouldn’t just wipe the dust off the leaves (cleansing) and call it a day. You’d water it (moisturizing), too, to keep it thriving.

Similarly, when you slather on that moisturizer, you’re not just quenching your skin’s thirst; you’re also locking in all that goodness, so your skin doesn’t go into panic mode. It's like giving your skin a big drink of water and a comforting hug.

And let’s not overlook the feel-good factor. Moisturizing is like the cherry on top of a great skincare routine. It can turn a mundane daily task into a luxurious ritual.

That moment when you glide a creamy, velvety moisturizer over your face can feel like an act of self-care and love. It’s your “me-time” encapsulated.

So, can you just cleanse and ignore moisturizer? Sure, if you want to live life on the edge.

But if you want your skin to be supple, happy, and resilient, it’s not the wisest move.

What Goes First: Moisturizer or Cleanser?


Well, let me paint you a picture.

Your skin, through the day or night, has been collecting a whole host of freeloaders: dirt, oil, dead skin cells, and environmental pollutants. They're all throwing a party on your face, and trust me, it's not the fun kind.

Here’s the scoop: when you cleanse, you're not just washing your face; you're prepping your canvas for greatness. Cleansing clears away the gunk, so your skin is in the optimal state to absorb the benefits of your moisturizer. It's like prepping the walls before painting; you want a smooth, clean surface for the best result.

But the magic really happens when you introduce moisturizer to the mix.

Now, if you’re visualizing slathering on moisturizer onto bone-dry skin, halt right there! Science has a little something to say about that.

When you apply moisturizer to damp skin, it's not just a feel-good step; it’s a move backed by some serious hydration science.

Damp skin acts like a sponge, quickly absorbing the moisturizer, which helps to lock in the water on the surface of your skin. It's like when you’re watering a thirsty plant, the soil soaks up that moisture much faster than if it were already saturated. And in skincare, timing is everything.

Think about the times you’ve felt your skin after a hot shower. It's soft, it's supple, and it's the perfect canvas for your moisturizer to work its magic.

By capitalizing on this prime time, you're giving your skin a hydration boost that's going to last. It's like filling up your gas tank before a long journey — it just makes sense.

But let’s break it down even further.

Your skin is home to a community of oils and moisture that it naturally produces. This community is pretty harmonious, but it does need some occasional TLC. That's where your moisturizer comes into play, replenishing any lost hydration and nutrients, and making sure that everything stays in balance.

And get this, the benefits of moisturizing post-cleansing extend beyond just feeling good. You're also helping to fortify your skin's barrier function.

That's your skin's own bouncer, keeping irritants out and moisture in. Without a strong barrier, your skin is like a fortress without walls — vulnerable to every invader that comes its way.

So, to answer the burning question: cleanser or moisturizer first? It’s a resounding, all-caps CLEANSER first, followed by MOISTURIZER on damp skin.

It’s this one-two step that’s going to keep your skin singing your praises.

Plus, it’s not just about looking good today; it's about setting the tone for healthier skin in the long run. Skincare is a marathon, not a sprint, and starting off on the right foot with the correct order can make all the difference.

Tying It All Together: Your Skincare Symphony

Now, let's bring it back to you.

Your skin is as unique as your fingerprint, and how you treat it can be a game-changer in your daily routine.

It's not just about slapping on some products; it's a self-care ritual. It's about taking that moment to give back to your skin for all it does for you.

After all, it's your body's largest organ, and it deserves some TLC!
