Experience a professional-grade "peel in a bottle" with the ISNTREE Hyper Acid4 AHA BHA PHA LHA 30 Serum. This potent, wash-off exfoliating treatment is designed to transform rough, congested, and dull skin into a smooth, glass-like complexion in just one minute.

If you struggle with stubborn blackheads, textured skin, or a "muddy" skin tone, this high-concentration acid blend is your shortcut to a total skin reset.

Why It’s a Total Game-Changer?

The Hyper Acid4 Serum is a powerful multi-exfoliant. While most serums use only one type of acid, this formula uses four different types to target every layer of your skin simultaneously.

  • Pore Detox: Deeply cleanses inside the pores to shrink their appearance.
  • Textural Smoothing: Gently "melts" away the rough bumps and dead skin cells on the surface.
  • Instant Brightening: Reveals a fresh, glowing layer of skin underneath.
  • The 1-Minute Rule: You only need 60 seconds to see a visible difference.

    Key Ingredients
    Hero ingredient: Exfoliating acids

    - Skin-conditioning agents: Help improve the feel of softness and smoothness.

    How to Use Apply a small amount after cleansing and toning, then seal with moisturizer. Introduce active formulas gradually. Routine Order - Morning: Use sunscreen daily. Acid products are usually better introduced in the evening unless directed otherwise. - Evening: Cleanser → this product 1-3 nights weekly → moisturizer. Avoid layering with retinoids or strong exfoliants the same night. Application Steps - Apply to clean, dry skin after cleansing. - Start 1-3 times weekly depending on skin tolerance. - Use a thin layer and avoid the eye area. - Follow with a calming moisturizer. - Do not layer with retinoids, benzoyl peroxide or other strong exfoliants in the same routine. - Use sunscreen daily because exfoliating acids can increase sun sensitivity. - Reduce frequency if dryness or stinging appears. - Avoid on broken, freshly waxed or irritated skin.
