AHAs vs BHAs for Men: The Complete Guide (2026)
AHAs vs BHAs for Men: The Complete Guide to Chemical Exfoliants
(and Which One You Actually Need).
If you’ve ever wandered down the skincare aisle, seen the words "glycolic acid" and "salicylic acid" on neighbouring bottles, and quietly walked away pretending you didn’t see them. This one’s for you.
Chemical exfoliants are the most misunderstood category in men’s skincare. The names sound like school chemistry. The instructions sound contradictory. Half the internet tells you they’ll transform your skin; the other half says they’ll burn your face off. The truth, in one paragraph: AHAs and BHAs for men are some of the most effective, best-studied
ingredients in skincare. Used correctly, they’re the difference between men who look after their skin and men who just hope for the best. Used wrong, they’re the fastest route to a red, peeling face and a regretful Monday morning.
This is the full men’s guide. What they are, every type you’ll see on a label, which one you actually need, and how to add one to your routine without anything going wrong.
What Are AHAs and BHAs? (In Plain English)
Your skin sheds dead cells constantly. Ideally, those cells fall off on their own and fresh skin takes their place. In practice, especially once you’re past 30 that process slows down. Dead cells pile up on the surface, which is why your skin starts to look dull, textured, or covered in blackheads in the same places no matter how often you wash your face.
Chemical exfoliants dissolve the "glue" that holds those dead cells together, letting them shed cleanly. Unlike a physical scrub, they don’t scratch or tear your skin. They work at the molecular level.
Here’s the difference you need to remember:
• AHAs (alpha hydroxy acids) are water-soluble. They work on the surface of your skin texture, tone, smoothness, early fine lines.
• BHAs (beta hydroxy acids) are oil-soluble. They go through oil, which means they can get inside your pores and clear them from the inside. This is why BHAs are the go-to for blackheads, whiteheads, and acne.
• PHAs (poly hydroxy acids) are the newer, gentler cousin. Same basic mechanism, bigger
molecules, slower penetration, less irritation. That’s the whole system.

The Difference Between AHAs and BHAs, Simplified!
One-line version: AHAs work on your skin’s surface. BHAs go inside your pores.
One-line version: AHAs work on your skin’s surface. BHAs go inside your pores.
If you had to pick based on concern alone:
• Dull, textured skin, uneven tone, early fine lines → AHA.
• Blackheads, whiteheads, oily skin, acne-prone → BHA.
• Sensitive, reactive, or first-timer → PHA.
A lot of men actually need both. BHA on the T-zone for oil and blackheads. AHA on the cheeks for texture and tone. You don’t need two separate bottles. A well-built exfoliant combines them at the right ratio.
Every Type of AHA You’ll See on a Label
There are six AHAs you’ll regularly see. They all work on the same principle but differ on molecule size (which controls penetration depth and irritation potential) and where the ingredient originally came from.)
1. Glycolic Acid — The Heavy Hitter
The most studied, most penetrating, most dramatic of the AHAs. Smallest molecule, which means it goes the deepest. Great for results, highest irritation risk if you push the percentage too fast. Derived from sugarcane.
• Best for: men past 35 with dullness, fine lines, or uneven tone.
• Start at: 5%. Never start at 10%. You’re not special.
• Watch for: dryness, tingling, flakiness in the first 2 weeks. Normal. If it burns, stop.

• Watch for: dryness, tingling, flakiness in the first 2 weeks. Normal. If it burns, stop.
2. Lactic Acid — The Gentle Workhorse
Bigger molecule than glycolic, so it penetrates less and irritates less. Bonus: lactic acid is hydrating on top of exfoliating. A proper two-for-one. Historically derived from sour milk, now mostly bioferments.
• Best for: dry, sensitive, or first-time men who want the benefits without the sting.
• Start at: 5–10%.
• Good to know: lactic acid is one of the best AHAs for men with darker skin tones lower risk of post-inflammatory pigmentation.
3. Mandelic Acid — The One for Acne-Prone Men
The largest common AHA. Slowest penetration, gentlest effect, and interestingly antibacterial. Which makes it one of the few AHAs that genuinely works for acne-prone men. Often recommended by dermatologists for darker skin tones. Derived from bitter almonds.
• Best for: acne-prone, hyperpigmented, or sensitive skin.
• Start at: 5–10%.
• Unique benefit: helps fade post-shave dark spots while preventing new breakouts.

4. Tartaric Acid — The Supporting Act
Less common as a headline ingredient. Derived from grapes. Strong antioxidant effect on top of gentle exfoliation. Usually plays a supporting role inside a blended AHA formula rounds out the performance without adding irritation.
5. Malic Acid — The Quiet Team Player
Derived from apples. Profile similar to tartaric, rarely headlines a product, often included in low concentrations to complement stronger AHAs. Good acid for men with sensitive, reactive skin when it’s blended rather than used solo.
6. Citric Acid — The One That’s Usually Not Exfoliating
You’ll see citric acid on almost every skincare label, but not always as an exfoliant. It’s often there to stabilize pH. At high enough concentrations (6%+) it exfoliates. At the low concentrations most products use, it’s a pH adjuster with a small exfoliation bonus.
Every Type of BHA You’ll See on a Label
BHAs are a much smaller family. Effectively, there are two you need to know and one natural precursor.
1. Salicylic Acid — The Main Event
Oil-soluble, anti-inflammatory, antibacterial. Penetrates into the pore lining and dissolves the oil + dead skin + bacteria mix that causes blackheads and acne.
Most formulations are 0.5% to 2%. Originally derived from willow bark, now mostly synthesized for consistency. This is the BHA in almost every product you’ll ever use.
• Best for: oily skin, blackheads, whiteheads, body acne, post-shave bumps.
• Use it: 2–3 nights a week, or as a cleanser daily at 0.5%.
• Pairs well with: niacinamide (calming), hyaluronic acid (rehydrating).
• Best for: oily skin, blackheads, whiteheads, body acne, post-shave bumps.
• Use it: 2–3 nights a week, or as a cleanser daily at 0.5%.
• Pairs well with: niacinamide (calming), hyaluronic acid (rehydrating).
2. Betaine Salicylate — The Gentler Alternative
The Korean-beauty workaround for men who can’t tolerate salicylic acid. Same target (pores, oil, acne),
slower delivery. If salicylic acid has irritated you in the past, betaine salicylate is the next thing to try.
• Best for: sensitive men who still need pore-clearing help.
• Typical concentration: 2–4%.
3. Willow Bark Extract — The Natural Precursor
Willow bark contains salicin, which the skin converts into salicylic acid. Much lower concentration and gentler action than synthesized salicylic acid. Won’t clear a serious breakout, but it’s a solid natural option for mild congestion or men who prefer plant-derived formulas.

PHAs: The Gentler Cousin Worth Knowing About
PHAs (poly hydroxy acids) are the newest category. They work on the same exfoliation principle as AHAs, but with much larger molecules. Which means they stay on the surface rather than penetrating deeply. Less irritation. Slower results. A strong choice for sensitive skin, first-timers, or men whose barrier is already damaged.
The three PHAs you’ll see on labels:
• Gluconolactone — the most common. Also attracts water, so it hydrates as it exfoliates.
• Lactobionic acid — powerful antioxidant, very gentle exfoliation.
• Galactose — rarely solo, often in blends. Mildest of the three.
Think of PHAs as the gateway acid. Not as transformative as a proper AHA or BHA, but much safer to experiment with while you learn how your skin responds.
Which AHA or BHA Should Men Actually Use?
Match your skin to one of these:
• Oily, blackhead-prone, T-zone shine → BHA (salicylic acid), 2–3 nights a week.
• Dull, uneven tone, early fine lines → AHA (glycolic or lactic acid), 2 nights a week.
• Acne-prone with hyperpigmentation → Mandelic acid, 2–3 nights a week.
• Sensitive skin or first-timer → PHA or low-percentage lactic acid, 1–2 nights a week.
• Combination skin / both concerns → Multi-acid blend, or alternate AHA and BHA on different nights.
• Oily, blackhead-prone, T-zone shine → BHA (salicylic acid), 2–3 nights a week.
• Dull, uneven tone, early fine lines → AHA (glycolic or lactic acid), 2 nights a week.
• Acne-prone with hyperpigmentation → Mandelic acid, 2–3 nights a week.
• Sensitive skin or first-timer → PHA or low-percentage lactic acid, 1–2 nights a week.
• Combination skin / both concerns → Multi-acid blend, or alternate AHA and BHA on different nights.
The number-one rule: One exfoliant. Not three. You don’t need a shelf of acids. You need one that works.
How to Add AHAs or BHAs to Your Routine (Without Wrecking Your Skin)
Start low. Start slow. Resist the urge to "push through" irritation. That’s your barrier waving a white flag.
Week 1–2: once a week, at night.
Week 3–4: twice a week.
Week 5+: three times a week, maximum.
Week 3–4: twice a week.
Week 5+: three times a week, maximum.
The basic sequence:
1. Cleanse and pat skin completely dry.
2. Apply your AHA or BHA. Pea-sized amount. Let it sit 60 seconds.
3. Follow with a hydrating serum or moisturizer.
4. Sunscreen the next morning. Non-negotiable. Chemical exfoliants make your skin significantly more sun-sensitive. The Mistakes Most Men Make With Chemical Exfoliants
5. Starting too strong. A 10% glycolic doesn’t work 2x faster than a 5%. It just hurts 2x more.
6. Using one every night. More isn’t faster. It’s barrier damage.
7. Combining with retinol on the same night. Either/or, not both.
8. Skipping sunscreen. You’ll undo everything in a week.
9. Buying three different exfoliants. Pick one. Master it. Move on.
How Often Should Men Chemically Exfoliate?
Rough guide:
• Oily, resilient skin → 3 nights a week.
• Normal / combination skin → 2 nights a week.
• Dry or sensitive skin → 1 night a week, or a PHA blend.
Listen to your skin. If it feels tight, rough, or red the morning after, You’ve gone too far. Scale back.
AHAs, BHAs, and Your Other Actives
• Retinol + AHA/BHA → not the same night. Alternate.
• Vitamin C + AHA/BHA → fine at opposite ends of the day. C in the morning, acid at night.
• Niacinamide + AHA/BHA → fine together. No conflict.
• Benzoyl peroxide + AHA/BHA → cautiously. Both are drying. Alternate nights if combining

Frequently Asked Questions (FAQ)
Is AHA or BHA better for men’s skin?
Neither is "better." BHAs are better for oily, acne-prone, or blackhead-prone skin. AHAs are better for dullness, texture, and early fine lines. Most men benefit from one or the other based on their main concern or a product that blends both.
Can men use AHA and BHA together?
Yes, but in the right way. Use them in a single well-formulated product (multi-acid blend) or on alternating nights. Don’t stack two separate exfoliants on the same night. That’s a quick way to barrier damage.
How often should men use AHA or BHA?
2–3 nights a week for most men. Once a week if your skin is dry or sensitive. Daily use is only appropriate for cleansers with very low concentrations (0.5% salicylic acid, for example).
Do AHAs and BHAs make your skin worse before it gets better?
Sometimes. The first 2–4 weeks can look worse. Minor dryness, flakiness, or small breakouts as congestion surfaces. If irritation is severe or lasts past 4 weeks, you’re over-exfoliating or using too high concentration.

Which AHA is best for men with darker skin?
Mandelic acid and lactic acid are typically the best choices. Larger molecules, gentler penetration, and a lower risk of post-inflammatory hyperpigmentation. A bigger concern for men with Fitzpatrick IV–VI skin.
The Bottom Line
AHAs and BHAs are some of the most effective actives in men’s skincare, when you pick the right one for your skin and use it properly. The mistake men make is assuming harder equals better. Lower percentages, used consistently, beat high percentages used aggressively every single time. At &SOM we built our exfoliating products around low-to-medium percentages, multi-acid blends, and natural supporting ingredients that calm the skin as they exfoliate because performance doesn’t have to come with a side of chemical burn.
Pick one. Use it 2–3 nights a week. Wear sunscreen. That’s the whole game.
