This is one of the most well-known AHA exfoliants, primarily used for treating dull skin, uneven skin tone, visible pores, and uneven skin texture.
But what exactly does glycolic acid do? Who is it recommended for, how should it be incorporated into the routine, and when should caution be exercised with it?
Let's take a step-by-step look!
What is glycolic acid?
Glycolic acid is a chemical exfoliant that belongs to the alpha-hydroxy acids (AHAs) . It can be derived from plant sugars, including sugarcane, and is one of the acids with the smallest molecular size among AHAs.
As a result, it can effectively work on the surface of the skin and help loosen the connections between dead skin cells.
The result of regular, properly dosed use may include:
- smoother skin surface,
- brighter appearance,
- more even skin tone,
- finer skin texture,
- less prominent pores.
Maruderm's previous professional materials also highlight that glycolic acid is one of the most well-known AHA exfoliants, which is used, among other things, to care for uneven texture and the appearance of pigmentation spots.
How does glycolic acid work?
Dead skin cells continuously accumulate on the surface of the skin. If they do not leave properly, the skin may appear duller and more uneven, and the pores may also become more pronounced.
Glycolic acid helps to loosen dead skin cells, thus supporting the skin's natural renewal process.
This is used among other things for:
✨ caring for dull skin
✨ in case of uneven skin tone
✨ alongside visible pores
✨ improving uneven skin texture
✨ reducing the appearance of pigmentation spots
✨ achieving smoother, fresher skin.
However, it is important to note that glycolic acid does not literally "scrub" the skin. Chemical exfoliation helps to remove dead skin cells in a controlled manner.
On which skin can it be particularly useful?
Glycolic acid can be incorporated into the routine of various skin types, but it may be especially interesting for those who:
- have dull, lifeless skin,
- experience uneven skin tone,
- struggle with visible pores,
- want to reduce the appearance of pigmentation spots,
- want a smoother skin surface.
On oily and combination skin the exfoliating effect may be interesting in cases related to sebum and dead skin cell issues.
It can also be used on dry skin , but it is particularly important to proceed gradually and ensure proper hydration.
Sensitive skin prone to redness or rosacea should be treated much more cautiously. In such cases, glycolic acid is not necessarily the first active ingredient we would choose.

We recommend using the tonic 2–3 times a week, in your evening routine , depending on your skin's sensitivity.
In addition to using the product, it is especially important to ensure proper sun protection during the day. Furthermore, we would like to emphasize the importance of conducting a patch test on a small area to avoid any potential irritation.

How to use glycolic acid?
The most important rule: do not start with too frequent use.
A simple evening routine might look like this:
Step 1 – Gentle cleansing
Cleanse your face and then pat dry.
2.Step 1 – Glycolic Acid
Apply the product containing glycolic acid according to the product's usage instructions.
Step 3 – Hydration
After exfoliation, use a moisturizing, comfort-providing product.
Step 4 – Sun Protection the Next Day
Always use an appropriate SPF in the morning.
It is recommended to use Maruderm's 7% tonic 2-3 times a week according to the manufacturer's recommendation.
Why is sunscreen important alongside glycolic acid?
This is one of the most important rules.
Consistent sun protection is especially important when using exfoliants, so alongside your glycolic acid routine, apply a broad-spectrum sunscreen with appropriate SPF. every morning.
The use of sunscreen is important not only for skin protection but also because if you are working on lightening pigmentation spots, increased UV exposure can easily hinder your goal.
What should you not combine in the same routine?
Glycolic acid is an active ingredient on its own, so it may not be advisable to use it simultaneously with every other strong active.
Especially as a beginner, be cautious with the following combinations:
- retinol and other retinoids,
- other AHA acids,
- BHA/salicylic acid,
- strong exfoliating products,
- high-concentration active formulas.
This does not mean that these ingredients cannot be included in the same routine at all. Rather, it is advisable to use them in separate routines or on different days, and monitor the skin's reaction.
The most common mistake: "if it works, I use it every day"
With glycolic acid, more does not necessarily mean better.
If you use too many active products too often at the same time, the skin can easily become irritated, red, or sensitive.
Therefore, it is worth:
✔️ starting with a lower frequency
✔️ monitoring the skin's reaction
✔️ properly hydrating
✔️ avoiding the combination of too many active ingredients
✔️ using sunscreen every morning.
When can results be expected?
In skincare, it is rarely advisable to expect dramatic changes overnight.
With regular and proper use, you may gradually notice that:
- the skin appears smoother,
- the overall appearance becomes fresher,
- the skin tone looks more even,
- the skin may appear more radiant,
- certain skin texture issues may appear less pronounced.
The exact results, of course, depend on the condition of the skin, the concentration used, and the other elements of the routine.
Who is it not recommended for or when should one be particularly cautious?
Glycolic acid is an active exfoliant, so it is not the ideal choice in every situation.
Use with particular caution if:
- your skin is very sensitive,
- your skin barrier is damaged,
- your skin is irritated or peeling,
- you have active skin inflammation,
- or you are prone to rosacea or eczema.
If you experience a strong burning sensation, persistent redness, or significant irritation after using a product, discontinue use.
