Exfoliation for Beginners: AHA vs BHA vs Enzymes
Share
In this article +
Exfoliation can make skin look smoother and brighter, but it is also one of the easiest skincare steps to overdo.
The key is not choosing the “strongest” exfoliant. It is understanding how different exfoliating methods work, what skin concern you are trying to address and how often your skin actually needs them.
AHA, BHA and enzyme exfoliants are often grouped together, but they do not work in exactly the same way.
What Does Exfoliation Actually Do?
Exfoliation helps remove or loosen dead skin cells from the surface of the skin.
Depending on the exfoliating ingredient, it can help improve the appearance of rough texture, dullness, clogged pores or uneven-looking tone.
The result depends on the type of exfoliant, concentration, formula, frequency and your skin's tolerance.
Chemical vs Physical Exfoliation
Physical exfoliation uses particles or textured materials to manually lift surface build-up from the skin.
Chemical exfoliation uses acids or enzymes to loosen the bonds between dead skin cells.
Neither method is automatically “good” or “bad”. The important factors are particle shape, pressure, frequency, concentration and skin condition.
For reactive or compromised skin, aggressive scrubbing can be uncomfortable, while a well-formulated chemical exfoliant can sometimes provide a more controlled option.
What Are AHAs?
AHA stands for Alpha Hydroxy Acid.
AHAs are water-soluble exfoliating acids that mainly work at the skin surface and are commonly used for rough texture, dullness and uneven-looking tone.
Common AHA examples
- Glycolic Acid
- Lactic Acid
- Mandelic Acid
These acids differ in molecular size, strength and how they feel on the skin, so they should not be treated as interchangeable.
Glycolic Acid: A More Direct Surface Exfoliant
Glycolic Acid is one of the best-known AHAs.
Lueur Beauté Glycolic Acid Exfoliating Toner contains 5% Glycolic Acid.
It is designed to help:
- remove visible skin build-up
- improve the appearance of rough texture
- support a brighter-looking complexion
- promote a more even-looking skin tone
The formula also contains Glycerin, Betaine and Sodium PCA to support moisture and skin comfort.
Use it on clean, dry skin in the evening a few times per week. Sensitive skin should introduce it gradually.
There is no need to wait 5–10 minutes after application unless the product instructions specifically say so. The current directions simply say to apply it and continue with the appropriate evening routine.

Lactic Acid: Exfoliation With Added Hydration Support
Lactic Acid is another AHA commonly used when the goal is smoother, brighter-looking skin.
Lueur Beauté AHA Peeling Concentrate contains 10% Lactic Acid and 1% Hyaluronic Acid.
It is designed to help improve the appearance of:
- dull or tired-looking skin
- pigmentation spots
- fine wrinkles
- uneven-looking complexion
This formula is an overnight leave-on treatment and should be used 1–2 times per week.
It is COSMOS NATURAL certified by ECOCERT Greenlife, with 100% ingredients of natural origin and 2% of organic origin.
Parfum/Fragrance is not listed in the INCI.

What Is BHA?
BHA stands for Beta Hydroxy Acid.
The best-known BHA in skincare is Salicylic Acid.
Salicylic Acid is oil-soluble and is commonly used in formulas for oily, blemish-prone and congested-looking skin.
Salicylic Acid for Oily and Congested-Looking Skin
Lueur Beauté Purifying Toner contains Salicylic Acid together with Lavender Flower Water, Cucumber Extract, Sweet Flag Root Extract, Glycerin and Betaine.
The formula is designed to help:
- remove excess impurities and sebum
- help clear pores of build-up
- refresh oily and combination skin
- support a clean, balanced feel
The manufacturer lists normal and oily skin types and specifically positions the toner for oily and combination skin concerns.
It is COSMOS NATURAL certified by ECOCERT Greenlife, with 99% ingredients of natural origin and 7% of organic origin.
The product is labelled Fragrance Free / No Added Fragrance, although it has a natural botanical aroma from the ingredients themselves.
What About Enzyme Exfoliants?
Enzyme exfoliants use enzymes, often derived from fruits or other botanical sources, to help loosen dead surface cells.
They are sometimes chosen by people who prefer a non-acid exfoliation approach.
However, “enzyme” does not automatically mean “safe for sensitive skin”. Formula strength, concentration and the rest of the ingredients still matter.
AHA vs BHA vs Enzymes: What Is the Main Difference?
AHA
Best suited when the main goal is improving visible surface texture, dullness or uneven-looking tone.
BHA
More relevant when excess oil, clogged pores and blemish-prone skin are the main concerns.
Enzymes
Can provide a gentler-feeling alternative for some users, but the complete formula still determines how well the product is tolerated.
How Do You Choose the Right Exfoliant?
If your skin looks dull or feels rough
An AHA such as Glycolic Acid or Lactic Acid may be relevant.
If your skin feels oily or congested
A Salicylic Acid product may be more appropriate.
If your skin is sensitive or reactive
Start slowly, avoid several exfoliating products at once and follow the exact product instructions.
A stronger acid is not automatically better, and an enzyme product is not automatically irritation-free.
How Often Should Beginners Exfoliate?
There is no universal schedule that fits every exfoliant.
The correct frequency comes from the product instructions and your skin's tolerance.
For example:
- Glycolic Acid Exfoliating Toner: a few evenings per week, introduced gradually
- AHA Peeling Concentrate: 1–2 evenings per week
- Purifying Toner: use according to its toner directions and your skin tolerance
More frequent use does not automatically produce better results.
What Are Signs of Over-Exfoliation?
Signs that your routine may be too aggressive can include:
- persistent tightness
- redness
- stinging when applying otherwise comfortable products
- increased dryness
- a feeling that the skin is raw or uncomfortable
If this happens, simplify the routine and pause exfoliation until the skin feels comfortable again.

Can You Use AHA and BHA Together?
Some formulas combine different exfoliating acids, but beginners do not need to layer multiple separate exfoliants in the same routine.
If you are already using an AHA, BHA, retinoid or another strong treatment, adding more active steps can increase irritation risk.
A simpler routine also makes it easier to understand which product is actually working for your skin.
Should You Use SPF After Exfoliating?
Yes.
When exfoliating acids are part of your routine, daytime sun protection becomes especially important.
The AHA Peeling Concentrate specifically instructs users to apply broad-spectrum sunscreen the following day and avoid direct sun exposure after use.
The Glycolic Acid Exfoliating Toner also recommends sunscreen during daytime use of the product.
A Simple Exfoliation Routine

Cleanser → Glycolic Acid Exfoliating Toner → Moisturiser
Evening with AHA Peeling Concentrate

Frequently Asked Questions
Is Glycolic Acid stronger than Lactic Acid?
Not always in practice. Concentration, pH and the complete formula all affect how an acid performs and feels on the skin.
Does Glycolic Acid Exfoliating Toner contain fragrance?
No added artificial fragrance is stated. Its soft floral aroma comes from plant-derived ingredients in the formula.
Does Purifying Toner contain fragrance?
The manufacturer labels it Fragrance Free / No Added Fragrance. Its subtle aroma comes naturally from the botanical ingredients.
Is AHA Peeling Concentrate fragrance-free?
Parfum/Fragrance is not listed in the current INCI, and no specific aroma is stated in the product information.
Can sensitive skin use exfoliating acids?
Possibly, but the product should be introduced slowly and according to its directions. Sensitive-skin suitability should not be assumed unless the product information specifically supports it.
Do I need to wait after applying an acid toner?
Not unless the product directions tell you to. The current Glycolic Acid Exfoliating Toner instructions do not require a 5–10 minute waiting period.
The Most Important Rule: Match the Exfoliant to the Concern
AHA, BHA and enzyme exfoliants are tools, not rankings.
The best option depends on what you want to improve, how your skin tolerates exfoliation and how the product is formulated.
Start with one exfoliating product, follow its directions and avoid turning exfoliation into a competition for the strongest formula.
