by Yu-Jun Park 30 Jan 2024

Hey, skincare enthusiasts!

Are you ready to dive into the world of acids? (without feeling like you’re in a high school chemistry class)

Let’s talk about a duo that’s creating a buzz in the world of Korean skincare: salicylic acid and glycolic acid.

Why settle for one when you can have both, right?

This isn't just a fad – it’s a game-changer for your skin routine.

So, buckle up as we explore how to mix these potent ingredients like a pro!

Can I Use Salicylic Acid and Glycolic Acid in the Same Routine?

Short answer? Absolutely, you can use salicylic acid and glycolic acid together. And they can be quite the dream team. Imagine Batman and Robin, but for your skin.

First, let's spotlight salicylic acid.

It's like the skincare equivalent of a deep-sea diver, plunging into the depths of your pores.

Known scientifically as a beta-hydroxy acid (BHA), salicylic acid is oil-soluble, meaning it can cut through the sebum and grime to unclog your pores.

Think of it as your personal pore police, keeping blackheads and breakouts at bay. Its anti-inflammatory properties are the cherry on top, soothing red, angry spots like a skincare whisperer.

Now, enter glycolic acid, the gentle giant of exfoliation.

Hailing from the alpha-hydroxy acid (AHA) family, glycolic acid is water-soluble and works on the surface level.

Its superpower lies in its tiny molecular size, allowing it to exfoliate the skin with the finesse of a skilled sculptor.

Glycolic acid unglues dead skin cells, revealing brighter, more youthful skin beneath. It's like an eraser for dullness and sun damage, smoothing out fine lines and pigmentation with a stroke of genius.

When these two acids come together, it's not just a routine; it’s a revolution.

Combining salicylic and glycolic acid creates a holistic approach to skincare. Salicylic acid keeps your pores in check, while glycolic acid ensures the surface of your skin is smooth and radiant.

This combination targets various skin concerns - from acne and oiliness to aging and dullness. It's like having a skincare army at your service, ready to tackle any challenge.

But remember, with great power comes great responsibility (to quote from another superhero movie!).

While salicylic and glycolic acid are a dream team, they can also increase your skin's sensitivity to the sun. So always follow up with a broad-spectrum sunscreen – think of it as your skincare shield against UV rays.

Should You Use Glycolic Acid or Salicylic Acid First?

In the grand ballet of skincare, sequencing is often seen as the key to a flawless performance.

But let's twist the narrative a bit: when it comes to the dynamic duo of glycolic and salicylic acid, the spotlight isn’t on the order, but on their harmonious performance together.

Let's dive into the nitty-gritty of why this order might not be as critical as you think and how, in the world of K-Beauty, these acids are choreographed to perfection.

Picture this: glycolic acid, the smallest molecule in the alpha-hydroxy acid (AHA) family, known for its ability to tiptoe across the upper layer of your skin, gently nudging away dead skin cells. It’s like a gentle breeze that sweeps away the old, revealing a luminous, fresh complexion underneath.

On the other hand, salicylic acid, a beta-hydroxy acid (BHA), plays a different tune. Oil-soluble and more direct, it dives deep into the pores, cutting through the oil and debris, preventing the sinister plot of acne and blackheads.

Now, conventional wisdom might suggest a strict regimen: apply water-soluble products (like glycolic acid) first, followed by oil-soluble ones (like salicylic acid).

However, in the innovative world of Korean skincare, the rules aren't so rigid. The beauty lies in the versatility and adaptability of these ingredients.

Imagine a serum or cream, a masterful blend of both glycolic and salicylic acid, artfully formulated to deliver the benefits of both in a single, elegant step.

This isn't just a formulation; it's a skincare revolution in a bottle. It's like having a multi-tool in your beauty arsenal, versatile and potent. Shout out to our wallet-friendly all-in-one Kojic Acid Serum here!

This approach not only simplifies your routine but also ensures that the acids work in synergy, complementing each other's strengths without the fuss over order.

But, for the skincare connoisseurs who love to layer separately, here's a tip: start with salicylic acid.


Because its oil-soluble nature allows it to penetrate deeply into the pores, laying the groundwork for glycolic acid to work on the surface.

It's like setting the stage before the main act. Once the salicylic acid has been absorbed, glycolic acid comes into play, working its magic on the surface, removing dead skin cells and boosting skin renewal.

This methodical approach is akin to a well-orchestrated symphony, where each note complements the other, creating a harmonious melody.

Which Is More Powerful: Salicylic Acid or Glycolic Acid?

Dive into the world of skincare, and you'll soon discover it's not just about power; it's about precision.

Asking which acid is more powerful between salicylic and glycolic is like asking whether a knight's sword is mightier than a wizard's wand.

They both wield their power differently, and understanding this is key to unlocking a skincare regime that's not just effective, but transformative.

Let's zoom in on salicylic acid first.

This BHA (beta-hydroxy acid) is oil-soluble, meaning it can penetrate the lipid layers of the skin and unclog pores from within. It's a true knight in shining armor for those with oily, acne-prone skin.

Salicylic acid delves deep into the skin's pores, breaking apart the debris and sebum that lead to acne. It's also a potent anti-inflammatory agent, calming inflamed, angry pimples and reducing redness. It's like having a microscopic superhero that dives into the pores to fight the evil forces of acne and oiliness.

Now, let's shift the spotlight to glycolic acid.

Hailing, as we’ve seen, from the AHA (alpha-hydroxy acid) family, glycolic acid is water-soluble and works on the skin's surface.

To refresh your memory on some of the technical bits: Its small molecular size allows it to exfoliate the skin with the finesse of a skilled artist, gently removing dead skin cells to reveal a brighter, more youthful complexion.

Glycolic acid is like the wizard in the skincare realm, casting spells to accelerate cell turnover, diminish fine lines, and fade hyperpigmentation. It's not just about peeling away the old; it's about revealing the new, radiant skin underneath.

So, which is more powerful? It's not about power; it's about purpose.

Salicylic acid is your go-to for deep pore cleansing and combating acne, while glycolic acid reigns supreme in surface-level exfoliation and tackling signs of aging.

What NOT to Mix with Salicylic and Glycolic Acid?

While we love a good mix, some things just don’t blend well.

And when you’re orchestrating the perfect skincare routine, knowing what not to mix is just as crucial as knowing what to mix.

It's like being a DJ at the trendiest club in town; you need to know which tracks blend harmoniously and which ones will clear the dance floor.

In the world of K-Beauty, where salicylic acid and glycolic acid are the stars of the show, there are certain ingredients that you might want to leave out of the mix.

Let’s dive into why some ingredients, although great solo artists, don’t make the best collaborators with our acid duo.

First up, Vitamin C.

This powerhouse antioxidant is like the solo diva of skincare – incredible on its own but a bit too much when combined with our acid duo.

Vitamin C thrives in a different pH environment than salicylic and glycolic acids. When they’re put together, they can destabilize each other, reducing their effectiveness. It’s like trying to mix oil and water; they just don’t blend well.

Also, this combination can be a bit too intense for your skin, potentially leading to irritation and redness. It's best to let Vitamin C shine in the morning routine, while saving salicylic and glycolic acids for the nighttime gig.

Next, let's talk about retinol.

This superstar ingredient is known for its anti-aging prowess, but when mixed with salicylic and glycolic acids, it’s like having too many lead singers in one band.

Both retinol and our acid duo encourage skin turnover and exfoliation, but when used together, they can upstage each other, leading to irritation, dryness, and sensitivity.

Think of it like this: you wouldn’t drink espresso shots while riding a roller coaster, right? Same concept. It’s all about balance.

Let retinol take the night shift on alternate days from the acids to keep your skincare routine harmonious and effective.

Last but not least, benzoyl peroxide.

Known for its acne-fighting abilities, benzoyl peroxide is a bit of a lone wolf.

When combined with salicylic and glycolic acids, it can lead to an overkill situation. This combination can strip your skin of its natural oils, leading to dryness, peeling, and irritation.

It's like having too many cooks in the kitchen – things get chaotic.

Let benzoyl peroxide have its own spotlight moment, preferably in the morning, while our acid duo rocks the night routine.

Remember, simplicity is the golden rule in skincare. Salicylic and glycolic acids are potent enough to handle the main stage on their own.

Avoid overcomplicating your routine with too many active ingredients. It’s not about how many products you use; it’s about using the right products at the right time.

Your Skincare, Your Rules

And there you have it, folks!

Mixing salicylic acid and glycolic acid is not just possible; it’s like giving your skin a VIP treatment.

With the K-Beauty wave making its mark globally, it’s clear that skincare is not just about following rules – it’s about understanding what works for you.

Whether you're using them in a single product or layering them like a skincare Picasso, the key is to listen to your skin.

Remember, in the world of Korean skincare, it’s all about embracing innovation and making it your own.

So, go ahead, experiment with confidence, and watch your skin thank you!
