    Description

    Isntree Hyper Acid4 AHA BHA PHA LHA 30 Serum – a new way of skin exfoliation

    The Isntree Hyper Acid4 AHA BHA PHA LHA 30 Serum is a unique chemical peel for intensive and thorough removal of dead skin cells in just one minute. It is an anthracite-colored, slightly thick serum that is rinsed off after one minute.

    The serum relies on chemical peeling action with four different acids at an optimal concentration of 30% AHA, BHA, PHA, and LHA. It is a highly effective, rinse-off peeling solution that gently smooths skin texture by removing dead skin cells and reducing excessive sebum production.

    Thanks to its special formula, it regulates excess sebum production after just one application, reduces the appearance of blackheads, and helps to smooth skin texture.

    It is best to use the serum in the evening before going to bed, as the skin is more susceptible to UV radiation afterwards. If you use it during the day, apply sunscreen generously afterwards.

    Recommended for

    • oily skin with large pores
    • blemish-prone skin and blackheads
    • flaky, rough, or uneven skin texture

    Active ingredients

    AHA: gently frees the skin surface from dead skin cells

    BHA: regulates excess sebum production, reduces the appearance of pores and blackheads

    PHA: removes dead skin cells, keeps the skin moisturized

    LHA: offers gentle skin exfoliation

    Niacinamide: evens out skin tone, regulates sebum production

    Allantoin: moisturizes and soothes the skin, removes dead skin cells

    Peat water: promotes cell regeneration, improves skin elasticity

    Charcoal powder: clarifies skin pores, balances the oil-water ratio in the skin

    For which skin types and concerns?

    Ideal for oily skin with enlarged pores, and for skin prone to blemishes and blackheads.

    Particularly suitable when a smoother skin texture and reduced sebum production are desired.

    How does it solve my skin problems?

    Hyper Acid4 Serum harnesses the power of AHA, BHA, PHA, and LHA to gently exfoliate blemished and oily skin. This combination of acids helps to regulate excess sebum production and visibly reduce blackheads. The serum clarifies pores and promotes a more even complexion.

    The use of niacinamide and allantoin not only balances skin tone but also soothes and moisturizes the skin. Peat water and charcoal powder support cell regeneration and improve skin elasticity, while simultaneously restoring the skin's oil-water balance.

    Users can look forward to refined pore structure and visibly smoothed skin texture, while the skin surface becomes noticeably softer. The serum is particularly suitable for those striving for clear, regulated, and well-cared-for skin.
