Lagom Micro Foam Cleanser: Full Ingredient Breakdown (2026)
By Victoria | Ingredient Analysis · Product Deep Dive
Lagom's Micro Foam Cleanser has built a loyal following in Korea for its dense, fine-bubble foam and "squeaky clean without the tightness" reputation. But marketing copy tells you what a product wants you to feel, not what's actually formulated into it. Here's what's really going on in the ingredient list, based on what the brand has disclosed.

The Core Formula: What's Actually Cleansing Your Skin
The primary surfactant doing the cleansing work here is Cocamidopropyl Betaine — a coconut-oil-derived cleansing agent that's a common, relatively gentle choice in Korean formulations, used as an alternative to harsher petroleum-based surfactants. This is paired with PEG-100 Stearate, which functions as both an emulsifier and a foam-texture booster, contributing to that dense, fine-bubble lather the brand is known for.
PEG-32 also appears, working as a binding agent, humectant, and solvent that helps the other ingredients blend into a stable formula. None of these are unusual or aggressive choices — this reads as a foam cleanser built for a gentle-but-thorough cleanse rather than a stripping, deep-pore-clearing formula.
Key Ingredients, Explained
| Ingredient | Function |
|---|---|
| Acacia Macrostachya Seed Extract (Aqualicia®) | A patented moisture-retention ingredient (US Patent 8642553). This is the brand's headline claim — it's marketed as helping activate the skin's water channels so cleansing doesn't leave skin as dehydrated. |
| Cocamidopropyl Betaine | Coconut-derived primary surfactant. Milder than sulfate-based cleansers, generally well-tolerated. |
| Urea | A humectant that helps bind moisture to the skin, partially offsetting the natural drying tendency of any foaming cleanser. |
| Phenoxyethanol, Chlorphenesin | Preservatives that keep the formula stable and prevent microbial growth — standard, widely used, and necessary in any water-based formula. |
| Potassium Hydroxide | A pH adjuster used in small amounts to keep the formula stable, not a harsh alkaline cleansing agent on its own. |
| Linalool, Limonene | Fragrance components, and two of the allergens Korea's MFDS requires brands to disclose. Worth noting if you have known fragrance sensitivities, even though the product is marketed as nearly unscented. |
Victoria's Note: One habit I picked up from years of reviewing export documentation is checking whether a brand discloses its full ingredient list and test certifications, not just the "hero ingredient" in the marketing copy. Lagom actually does this well — the fine-dust removal test and the 24/48-hour dermatologist patch test are both real, third-party-verified certifications, not just claims. That's the kind of transparency that should matter more to shoppers than a flashy patented-ingredient name.
Does It Live Up to the Claims?
The "gentle deep clean" claim: Reasonably backed. Cocamidopropyl Betaine is a genuinely mild surfactant choice, and the patch-test certification supports the low-irritation claim.
The "24-hour hydration" claim: This rests almost entirely on the patented Aqualicia ingredient plus urea. It's a legitimate humectant combination, but no cleanser — rinsed off within a minute of application — is going to hydrate skin for a full 24 hours on its own. Think of this as "less dehydrating than a typical foam cleanser," not a moisturizing treatment.
The "fine dust removal" claim: This one is actually verified by third-party lab testing (98.38% reduction in a simulated fine-dust test), which is more substantiation than most cleansers bother to provide.
Who Should (and Shouldn't) Use This
- Good for: Combination and oily skin that wants a thorough cleanse without the tight, stripped feeling of a harsher foam.
- Good for: Anyone who wears makeup or sunscreen daily and wants a cleanser that can handle a second-cleanse step without over-drying.
- Think twice if: You have a known fragrance allergy — this isn't fragrance-free, even though it's marketed as low-scent.
- Think twice if: You have very dry or barrier-compromised skin — foaming cleansers as a category, even gentle ones, aren't usually the best fit here. A low-pH gel or cream cleanser would be a better starting point.
FAQ
Is this cleanser low-pH?
The brand doesn't advertise a specific pH figure. Foam cleansers with this surfactant combination tend to sit closer to neutral or slightly alkaline rather than the low-pH (around 5.5) formulas often recommended for barrier health, so it's worth being mindful of that if pH is a priority for your routine.
Is the patented Aqualicia ingredient actually special?
It's a real, patented plant extract with documented moisture-channel research behind it — not a marketing invention. That said, "patented" describes the ingredient's novelty, not automatically its concentration or impact in this specific formula, which the brand doesn't disclose.
Is this cleanser fragrance-free?
No — it contains linalool and limonene, both fragrance-related allergens. It's marketed as low-scent rather than unscented, so check ingredient lists carefully if fragrance is a concern for your skin.
