ETUDE SoonJung 5.5 Foam vs 6.5 Whip: five checks for 150mL cleansers

Distinguish two Korean SoonJung cleansers, their sizes and a gentle cleansing routine.

AKJ Beauty's 2021 texture video of the SoonJung 5.5 Foam Cleanser; not a 2026 comparison with the Whip Cleanser. · AKJ Beauty (independent YouTube creator, 2021-05-26)

Korean beauty brand ETUDE lists SoonJung 5.5 Foam Cleanser 150mL and SoonJung pH 6.5 Whip Cleanser 150mL as separate items on its Korean official store. The Whip listing additionally offers a 250mL size and a 150mL refill option. Its global official shop also names the 5.5 Foam and 6.5 Whip separately. The numbers are product-label claims, not independent pH measurements by this editor; identical formulas or outcomes have not been established. AKJ Beauty's original 2021 video shows the earlier 5.5 Foam's texture only, not the current Whip Cleanser or a 2026 head-to-head test.

  1. 01

    Read the full product name

    Check whether the package says SoonJung 5.5 Foam Cleanser or SoonJung pH 6.5 Whip Cleanser. They are distinct listings even though both use the SoonJung name.

  2. 02

    Compare sizes and refills

    The Korean store lists the 5.5 Foam in 150mL and the 6.5 Whip in 150mL or 250mL plus a 150mL refill choice. Use refills only in suitable matching containers and check your actual regional offer.

  3. 03

    Cleanse gently with a small amount

    Follow the specific label directions. Wash your hands, wet your face with lukewarm water and gently cleanse using an appropriate amount. The older video demonstrates the 5.5 Foam format, not the 6.5 Whip pump.

    Rinse without harsh rubbing

    Keep cleanser out of the eyes. Rinse thoroughly with lukewarm water without aggressive scrubbing or repetitive cleansing.

  5. 05

    Pat dry and moisturize if needed

    Gently pat your face dry and apply moisturizer if appropriate. Stop use if irritation or a rash occurs, and seek professional care if symptoms are severe or persistent. Check the actual country-specific ingredient label.

ⓘ Keep in mind
