Quick answer

Choose the Micro Scrub Exfoliator 8% if you have oily, non-sensitive skin and want deeper pore cleansing and faster skin renewal. Choose the Micro Scrub Exfoliator 4% if you have normal or combination skin and prefer a gentler daily exfoliation that still brightens and smooths without irritation.

Why glycolic acid strength matters

Glycolic acid, an alpha hydroxy acid (AHA), works by dissolving the bonds between dead skin cells so they shed more easily. A higher percentage like 8% penetrates faster and delivers more noticeable results in fewer uses, but it also increases the risk of stinging or redness if your skin isn't accustomed to acids. The 4% version is milder, making it a better starting point for those new to chemical exfoliation or with slightly reactive skin.

How to match strength to your routine

If you already use retinol, vitamin C, or benzoyl peroxide, your skin's barrier may be more sensitive. In that case, the 4% strength lets you exfoliate without overloading your skin. For those whose main concern is clogged pores or dullness and who have no history of acid sensitivity, the 8% strength can be used 2-3 times per week for faster turnover. Both formulas use bamboo-based natural microbeads for physical exfoliation, so you get dual action without plastic particles.

Tradeoffs between the two strengths

  • Exfoliation depth vs. frequency: 8% works faster but you should limit use to 2-3 times per week. 4% allows daily or every-other-day use, making it easier to sustain a routine. If you want quick results and can handle a slower cadence, go 8%. If you prefer a daily habit, go 4%.
  • Skin compatibility: 8% is labeled for oily, non-sensitive skin only. 4% is safe for normal and combination skin but still not suitable for sensitive skin. Neither is formulated for very reactive or damaged barriers. If your skin is oily and resilient, 8% is a match. If your skin is normal to combination, 4% is the safer bet.
  • Price and value: Both products offer similar value, with the 8% version priced slightly higher at USD 48.84 versus USD 45.54 for the 4% version. Both are discounted from a USD 66.00 comparison price. The price difference is small. Let your skin type, not the cost, guide your choice.
