medicube 21% Acid Wash-off Exfoliant 1.41 fl oz — 1‑Minute AHA+BHA+Succinic Acid for Bumpy, Breakout‑Prone Skin

Designed in Korea with dermatologist input, this concentrated wash-off serum blends lactic acid (AHA), salicylic acid (BHA) and succinic acid to dissolve dead skin and excess sebum from pores quickly. Its short-contact format (apply, wait one minute, massage, and rinse) targets bumpy or congested areas without a long leave-on exposure, while patented soothing complexes help reduce irritation risk for sensitive or acne-prone skin when used as directed.

How does a one-minute wash-off exfoliant improve bumpy or breakout-prone skin?

The formula works by loosening and removing the surface buildup of dead cells, excess oil and pore debris that cause rough texture and blackheads. Because it rinses off after a minute, it delivers a high-concentration chemical peel effect without a prolonged leave-on step, making it easier to control sensitivity.

• 21% active acid complex combining lactic acid (AHA), salicylic acid (BHA) and succinic acid
• One-minute application to target congested zones or an all-over treatment once or twice weekly
• Rinse-off routine minimizes continuous acid exposure for sensitive skin
• Designed to dissolve sebum and dead skin to smooth texture and improve clarity

Is this safe for sensitive or acne-prone skin?

Medicube pairs the acid complex with patented soothing ingredients (Hydra Calm™ and Derma-Clera™) to help reduce irritation risk. A patch test is recommended prior to first use, and frequency should start low (once weekly) and increase as tolerated.

• Formulated with calming complexes to support skin barrier comfort
• Patch test advised on inner forearm or behind ear before facial use
• Start once per week, then increase to twice weekly if skin tolerates it
• Short contact time limits prolonged acid exposure for reactive skin

How do I use it within my existing skincare routine?

Use on clean, dry skin after cleansing. Apply two drops to the face, leave for one minute, gently massage to assist exfoliation, then rinse thoroughly with lukewarm water. Follow with soothing toner, moisturizer and daily sunscreen when used in daytime routines.

• Cleanse first, then apply 2 drops; leave 1 minute, massage, rinse
• Use once or twice weekly, increasing gradually based on tolerance
• Always follow with moisturizer; apply sunscreen the next morning
• Avoid concurrent strong exfoliants or retinoids on the same day to reduce irritation

What visible improvements can I expect and when?

Because the serum targets pore congestion and dead skin, many users notice smoother texture and reduced blackheads after a few applications. Results vary by skin condition and adherence to recommended frequency; long-term improvement in clarity and radiance typically appears after several weeks of consistent use.

• Immediate: smoother skin surface and clean-feeling pores after rinse
• Short-term (weeks): fewer visible blackheads and reduced bumpiness
• Ongoing: improved radiance and more even skin texture with regular use
• Individual responses depend on skin type and combination with supportive care

Who is this for: This product suits people with bumpy, congested or breakout-prone skin who want a powerful, short-contact chemical exfoliant. It is formulated for those seeking noticeable pore cleansing and texture improvement without a long leave-on acid treatment, and who will follow patch-test guidance and step-up frequency gradually. Not recommended for skin with open wounds or severe irritation; consult a dermatologist if unsure.
