Round Lab Soybean Panthenol Cleanser: Barrier-Respecting Cleanse With Soy Protein and B5

Round Lab expands into a fourth ingredient line here: soybean extract paired with panthenol (vitamin B5). The Soybean Panthenol Cleanser is a 150ml pump-dispensed foam cleanser at $33.50, formulated for the specific case of skin that gets stripped by most cleansers. Soybean proteins and isoflavones provide a barrier-protective layer during the cleanse; panthenol supports and calms; the surfactant system is engineered to rinse without removing the skin's natural lipids.

Korean cleansers broadly fall into three tiers: aggressive (clear oil, congestion removal), gentle (barrier-respecting for daily use), and "treatment" (contain ingredients like niacinamide or panthenol that do skincare work during the wash). This falls into the third category. The soybean protein content creates a film effect that protects the skin during cleansing, similar to how milky cream cleansers work but with a lighter foam finish.

What It Does

Soybean proteins create a temporary barrier film during cleansing, preventing over-stripping. Isoflavones provide antioxidant benefit. Panthenol (B5) reinforces barrier and hydrates. The gentle surfactant system lifts oil and debris without dismantling the skin's lipid matrix. Post-cleanse, skin should feel balanced, not tight or squeaky. For users who feel their skin needs a post-cleanse moisturizer immediately, this cleanser buys 3 to 5 extra minutes before that tight feeling sets in.

Who It's For

• Dry or mature-dry skin: Non-stripping formulation.
• Sensitive skin: Barrier-supportive rather than aggressive.
• Post-procedure recovery: Safe during healing phases.
• Users who get post-cleanse tightness: Addresses the stripped feeling at the cause.
• AM cleansing for dry skin: Gentle enough for daily morning use.

How to Use

Wet face with lukewarm water. Dispense 1 to 2 pumps onto damp hands. Lather and apply to face in gentle circles for 30 seconds. Rinse thoroughly.

Dry skin users may prefer to pat skin damp rather than fully dry after rinse, to maximize hydration retention.

FAQ

How does this compare to the Round Lab Birch Juice Cleansers or Soybean Panthenol Toner?

Birch Juice cleansers target hydration differently with sap extract. The Soybean Panthenol line is the most barrier-focused of Round Lab's cleanser options. If your concern is tight post-cleanse skin, this is the version to try. Follow with the matching Soybean Panthenol toner for the full line effect.

Does soybean cause allergy?

Topical soybean allergy is rare but possible. Users with severe soy food allergies should patch test before face application. Moderate soy food sensitivities rarely translate to topical reactions, but check on inner wrist first.

How does it compare to COSRX Low pH Good Morning Cleanser?

COSRX Low pH is ingredient-minimalist and pH-balanced but less rich. Round Lab Soybean is creamier with more active support (soybean protein + panthenol). For oilier skin: COSRX. For dry or mature skin: Round Lab.

Will it remove makeup?

Light makeup and sunscreen: yes, as a second cleanse after oil cleanser. Heavy makeup and waterproof: always oil-cleanse first. This is not a one-step cleanser for heavy makeup.

How long does 150ml last?

Twice daily use: 2 to 3 months. Once daily AM use: 4 to 6 months.
