Safety & compatibility
SAFEContains Salicylic Acid (BHA). While the concentration is low and it is a rinse-off product, consult your OB-GYN before use during pregnancy or breastfeeding as a precaution.
Contains Glyceryl Stearate, Caprylic/Capric Triglyceride, and Cetearyl Alcohol which may feed malassezia. However, as a rinse-off product with minimal contact time, the risk is significantly reduced.
Clinically tested with a skin irritation index of 0.00. Uses plant-based surfactants instead of SLS/SLES for minimal irritation. EWG Green certified.
Rated 1/5 for comedogenicity. As a rinse-off cleanser, pore-clogging potential is minimal since ingredients do not remain on the skin.
Safe to use alongside retinol, vitamin C, AHA, and BHA products. As a rinse-off cleanser, it will not interfere with active ingredients applied after.
Certified vegan product. No animal-derived ingredients and no animal testing. Formulated under eco-friendly practices in South Korea.

How to use
HOW TO USEWet Your Face
Splash your face with lukewarm water to prep the skin. Avoid hot water as it can strip natural oils and increase sensitivity.
Lather in Palms
Dispense a moderate amount (about a cherry-sized dollop) onto your palm and work into a rich foam with a small amount of water.
Gently Massage
Apply the foam to your face using gentle, circular motions for 30–60 seconds. Focus on oily zones (T-zone, nose, chin) where pores tend to be larger.
Rinse Thoroughly
Rinse off completely with lukewarm water. Pat dry with a clean towel and follow with your toner and the rest of your skincare routine.

Skin type compatibility
SKIN TYPESIdeal match. Controls sebum by 49.99%, deep cleans pores, and leaves a matte, refreshed finish without over-drying. Tannin Complex helps tighten pores.
Balances oily T-zone effectively while plant-based surfactants and Panthenol keep drier areas comfortable and hydrated.
Clinically tested for acne-prone skin. BHA clears pores, Azulene soothes inflammation, and the formula reduces blackheads and whiteheads over time.
Hypoallergenic with 0.00 irritation index. Azulene and Centella Asiatica provide soothing benefits. Patch test recommended for very reactive skin.
Gentle enough for daily use, but the sebum-controlling focus may not provide sufficient hydration. Follow immediately with a hydrating toner and moisturizer.
A solid everyday cleanser that maintains skin clarity and freshness. May be more targeted than necessary if you have no pore or sebum concerns.

2K+ REVIEWSPros & cons
BALANCEDPraised
- Extremely gentle formula with 0.00 skin irritation index — no stinging or tightness
- Effectively controls excess sebum and reduces oiliness throughout the day
- Rich, creamy foam from plant-based surfactants feels luxurious yet non-stripping
- Visibly reduces blackheads and whiteheads with consistent use over 4 weeks
- Fragrance-free, vegan, and EWG Green certified for clean beauty enthusiasts
- Azulene and Centella Asiatica soothe redness and calm acne-related inflammation
- Also available in a 250ml size for better value
Criticized
- BHA concentration is too low for aggressive acne treatment needs
- May feel slightly drying for very dry skin types if used twice daily
- Not a standalone makeup remover — requires double cleansing for heavy makeup
- Blackhead reduction results are modest (4.79%) and require patience
- Tube packaging makes it difficult to use every last drop of product
- Not 100% fungal acne safe due to certain emulsifying ingredients
Budget-friendly alternatives (dupes)
DUPESUses Betaine Salicylate (a gentler BHA derivative) and tea tree oil instead of azulene. Gel texture vs. creamy foam. Strong tea tree scent may bother sensitive noses. Can feel slightly more stripping than P.CALM.
A pH 5.5 foam cleanser with 13 botanical extracts. Gentler formula without BHA, so less pore-clearing power. Better suited for dry-sensitive skin that does not need sebum control.
Gel-type cleanser with Green Plum and AHA for brightening rather than BHA for pore control. Lighter texture with less foam. Lacks the sebum-controlling BADECA Complex and azulene soothing benefits.

Frequently asked questions
FAQUse with caution. The formula contains Salicylic Acid (BHA), which some healthcare providers advise limiting during pregnancy and breastfeeding. However, the concentration is very low and it is a rinse-off product with minimal skin contact time, which significantly reduces absorption. There are no retinoids, hydroquinone, or chemical sunscreens in the formula. We recommend consulting your OB-GYN or dermatologist before use during pregnancy or breastfeeding.
Not strictly fungal acne safe. The formula contains Glyceryl Stearate, Caprylic/Capric Triglyceride, Stearyl Alcohol, and Cetearyl Alcohol, which are esters and fatty alcohols that can potentially feed malassezia yeast. However, because this is a rinse-off product that stays on skin for only seconds, the practical risk is significantly lower than with leave-on products. Many users with fungal acne report no issues, but if you are highly sensitive, consider a confirmed malassezia-safe cleanser instead.
Yes. As a rinse-off cleanser, it does not leave active ingredients on the skin that could interact with your other products. The low-concentration salicylic acid in this cleanser is fully rinsed away before you apply serums or treatments. You can safely use it before applying retinol, vitamin C, AHA, BHA, or niacinamide products in your routine. If your skin is very sensitive and you are using strong prescription retinoids, consider using the cleanser only once daily.
This cleanser is best suited for oily, combination, and acne-prone skin types. It excels at sebum control, pore cleansing, and reducing blackheads and whiteheads. Sensitive skin types also benefit from its hypoallergenic formula (0.00 irritation index) and soothing ingredients like Azulene and Centella Asiatica. For dry skin, it works well but should be followed immediately with a hydrating toner and moisturizer to prevent any dryness.
You will feel a cleaner, refreshed complexion from the very first use. Visible improvements in oiliness and skin texture typically appear within 1–2 weeks. The most significant results, as demonstrated in clinical trials (49.99% sebum reduction, 19.29% whitehead reduction, 4.79% blackhead reduction), are observed after 4 weeks of consistent twice-daily use. Brightness improvement continues with longer-term use.
Use it as your water-based cleanser, which is typically Step 1 in a single-cleanse morning routine, or Step 2 in a double-cleanse evening routine (after an oil cleanser or cleansing balm). Apply it on damp skin, massage gently, then rinse. Follow with toner, serum, moisturizer, and sunscreen (AM). It can be used both morning and evening.
No. With a comedogenic rating of 1 out of 5, this cleanser has a very low risk of clogging pores. As a rinse-off product, ingredients are washed away within seconds and do not remain on the skin long enough to accumulate in pores. The formula is specifically designed to clean out pores (97.7% pore residue cleansing rate), not clog them. It is clinically tested for acne-prone skin.
The Period After Opening (PAO) is 12 months. The 150ml tube typically lasts 2–3 months with twice-daily use (a cherry-sized amount per wash). Store in a cool, dry place away from direct sunlight. If the product changes color, texture, or smell before the 12-month mark, discontinue use. A 250ml size is also available for those who want longer-lasting supply.
Verdict: The P.CALM UnderPore Foam Cleanser is an excellent daily cleanser for oily, combination, and acne-prone skin that delivers clinically-backed pore cleansing and sebum control in a remarkably gentle formula. Its plant-based surfactants, azulene soothing, and BHA exfoliation provide effective results without irritation — a rare balance in the cleanser category. While the BHA concentration is too low for serious acne treatment and it is not strictly fungal acne safe, it stands out as one of the best K-beauty foam cleansers for sensitive, breakout-prone skin. Best paired with a proper acne treatment serum for maximum results.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
