What is IPMP in Skincare? (And Why It's in Your Cleansing Balm)
You’ve probably seen IPMP listed on your K-beauty products and scrolled right past it. It’s not as flashy as niacinamide, not as famous as retinol, and not as trendy as centella. But here’s what the beauty industry doesn’t want you to know: IPMP might be one of the most underrated acne-fighting ingredients available.
If you’re acne-prone and nervous about oil cleansing (or already breaking out from it), IPMP could be the ingredient that changes everything.
What Is IPMP?
IPMP stands for Isopropyl Methylphenol. You might also see it called:
- 3-Methyl-4-isopropylphenol
- O-Cymen-5-ol
- Biosol
It’s an antimicrobial and antibacterial agent that’s been used in medical and personal care products for decades—but only recently gained attention in skincare, particularly in Korean beauty products.
Chemical Properties
Without getting too deep into organic chemistry:
- It’s a phenol derivative (similar structure to other antiseptics)
- Oil-soluble (which is why it works well in cleansing balms and oils)
- Stable across various pH levels
- Non-oxidizing (won’t degrade quickly like some other actives)
What this means for you: It’s effective in oil-based products where many other acne-fighting ingredients would fail.
How IPMP Works Against Acne
Unlike harsh acne treatments that dry out your skin or cause purging, IPMP works through targeted antimicrobial action.
Kills Acne-Causing Bacteria
IPMP is particularly effective against Propionibacterium acnes (now called Cutibacterium acnes)—the primary bacteria responsible for inflammatory acne.
How it works:
- Disrupts bacterial cell membranes
- Prevents bacterial growth and reproduction
- Works on contact, providing immediate antimicrobial action
The difference: Unlike benzoyl peroxide which kills everything (including good bacteria), IPMP is more selective.
Prevents Biofilm Formation
Acne bacteria form protective biofilms that shield them from your immune system and topical treatments. IPMP helps prevent these biofilms from forming.
What this means: Your other acne treatments can actually reach and work on the bacteria.
Anti-Inflammatory Action
IPMP doesn’t just kill bacteria—it also reduces the inflammatory response that causes red, swollen, painful pimples.
The benefit: Less redness and faster healing even while fighting active breakouts.
Doesn’t Disrupt Skin Barrier
Unlike many acne fighters (looking at you, benzoyl peroxide and alcohol-based products), IPMP doesn’t compromise your moisture barrier.
Why this matters: You can use it daily without the dryness, peeling, and irritation that makes acne worse.
IPMP vs Other Acne-Fighting Ingredients
Let’s compare IPMP to the heavy hitters everyone knows about:
IPMP vs Benzoyl Peroxide
Benzoyl Peroxide:
- Kills ALL bacteria (good and bad)
- Extremely drying
- Can bleach fabrics
- Causes irritation and peeling
- Very effective but harsh
IPMP:
- More selective bacterial action
- Non-drying
- Doesn’t bleach
- Gentle enough for daily use
- Effective but mild
Winner: IPMP for sensitive skin; benzoyl peroxide for severe acne that needs aggressive treatment
IPMP vs Salicylic Acid
Salicylic Acid:
- BHA that exfoliates inside pores
- Can be drying
- Photosensitizing
- Works on blackheads and whiteheads
- Takes time to see results
IPMP:
- Antimicrobial, not exfoliating
- Non-drying
- Not photosensitizing
- Works on inflammatory acne
- Works on contact
Winner: They work differently—use both for comprehensive acne treatment
IPMP vs Tea Tree Oil
Tea Tree Oil:
- Natural antimicrobial
- Can be irritating at high concentrations
- Strong smell
- Inconsistent potency between products
IPMP:
- Synthetic antimicrobial
- Gentle, low irritation risk
- No smell
- Consistent concentration and effectiveness
Winner: IPMP for predictable results; tea tree for those preferring natural ingredients
Why IPMP Works So Well in Cleansing Balms
Here’s where IPMP becomes really interesting: it’s one of the few anti-acne ingredients that’s oil-soluble and works effectively in cleansing products.
The Problem with Oil Cleansing and Acne
Many acne-prone people avoid oil cleansing because:
- Oil-based products can clog pores
- Some oils feed acne-causing bacteria
- The cleansing process can trap bacteria in pores
- Heavy oils can leave residue that causes breakouts
How IPMP Solves This
When IPMP is added to cleansing balms and oils:
- Kills bacteria during cleansing: While you’re massaging the product, IPMP is actively fighting acne-causing bacteria
- Prevents new breakouts: The antimicrobial action continues throughout the cleansing process
- Works in oil phase: Unlike water-based acne fighters, IPMP is effective in the oil-based first cleanse
- Doesn’t get rinsed away too quickly: Being oil-soluble, it stays in contact with skin longer during the cleansing process
The result: You get all the benefits of oil cleansing (makeup/sunscreen removal) without the breakout risk.
