Key Questions

  • Since this is a multi-acid formula, we don't recommend using other strong actives like retinol, benzoyl peroxide, glycolic acid, or lactic acid at the same time to minimize the risk of irritation.
  • Yes! This serum has been clinically tested and shown to be safe for sensitive, acne-prone skin. The formula is powered by 12% humectants to boost hydration and help counteract dryness and sensitivity from exfoliation. It also contains calming ingredients to ensure that acne-prone and sensitive skin can benefit from its potent formula without irritation.
  • If you’re new to exfoliating, you might experience a purge—meaning you may see small pimples and bumps appear. This is completely normal! Salicylic acid works by diving deep into pores and bringing underlying buildup to the surface. This phase can last a few weeks, so stick with it and continue to slowly incorporate it into your routine.
  • If you’re new to exfoliating, start slow—just a few times a week—and build up to daily use as your skin adjusts. You can use this serum in the AM or PM, but if you’re applying it in the morning, always follow with SPF.

    Banu blemish serum

    The Banu AHA + BHA serum with 2% salicylic acid has become a game-changer in my skincare routine.What impressed me most is how quickly I started seeing results. Within the first week of use, my skin texture began improving noticeably. The combination of AHA and BHA really works to tackle both surface-level concerns and deeper pore issues. My stubborn blackheads that l'd been dealing with for months finally started clearing up, and the overall clarity of my skin improved dramatically.The 2% salicylic acid concentration hits that sweet spot - strong enough to be effective without being too harsh or drying. I was worried it might irritate my somewhat sensitive skin, but I experienced zero irritation when I started with every other night application.The texture is lightweight and absorbs quickly without leaving any sticky residue. I love that I can layer it under my moisturizer without any pilling or greasiness. The bottle design is also practical with a dropper that makes application easy and hygienic.After using it for a few weeks now. my skin looks clearer, feels smoother, and my pores appear smaller. Even my partner noticed the difference! I'm genuinely excited to continue using this and see the long-term results.Would definitely recommend this to anyone dealing with blemishes, uneven texture, or clogged pores. This serum does exactly what it promises to do.Pros:Cons:Effective combination of AHA and BHANoticeable results within a weekLightweight, non-irritating formula…

    A MUST TRY!

    I’ve been using the BANU AHA BHA Blemish Clearing Serum as part of my nightly routine, and I’m genuinely impressed with how balanced and effective it is. As someone with dry skin who still deals with breakouts, I usually tread carefully with exfoliating serums—but this one is a game-changer. The mix of 2% salicylic acid and mandelic acid gently clears pores and smooths texture without leaving my skin tight or irritated. I love that it also includes niacinamide and 12% humectants to support hydration and barrier health. After just two weeks, my skin feels more refined, less oily, and visibly brighter. It layers beautifully under moisturizer and doesn't cause flaking or redness like harsher treatments. I also appreciate the clean, vegan formula that’s been tested on all skin tones and types—including acne-prone skin like mine. It’s gentle, hydrating, and actually works—definitely a must-try!

    What Is Salicylic Acid and Why It Belongs in Your Skincare Routine

    Let’s talk about one of the most proven, go-to ingredients in the acne world: salicylic acid. Technically, it’s a beta-hydroxy acid (BHA) — aka an oil-soluble chemical exfoliant that goes deep into pores to clear out dead skin cells and excess oil. Translation? It’s a total MVP for unclogging skin and calming breakouts before they blow up.
