Exfoliating acids vs scrubs: a practical buying guide

First separate the method from the product format

The American Academy of Dermatology (AAD) describes two approaches: mechanical exfoliation uses a scrub or tool, while chemical exfoliation uses ingredients such as alpha and beta hydroxy acids. It cautions that exfoliation is not suitable for everyone.

A cleanser, toner and scrub are different shopping formats, not three compulsory steps. Write the exact product name beside its role in your routine. If you cannot explain what a new bottle would add, leave it off the shopping list until you can.

Two Australian product pages show why directions matter

CeraVe Australia describes its SA Smoothing Cleanser as a rinse-off cleanser. The Ordinary’s Australian page presents its Glycolic Acid 7% Exfoliating Toner as an exfoliating toner and gives its own application instructions. These are manufacturer descriptions of different formats, not an independent comparison of their results.

Do not transfer a cleanser’s wash-off routine to a leave-on product, or assume a toner should stay on simply because of its name. Read the current directions for the exact bottle. Our comparison is about how to read those instructions, not a recommendation to use these two products together.

There is no universal exfoliation calendar

The AAD says frequency depends on the method and the person’s skin. It also warns that adding exfoliation to retinol, prescription retinoids or benzoyl peroxide can worsen dryness. Avoid exfoliating sunburned skin or open cuts, and ask a dermatologist if you are unsure whether exfoliation suits you.

For a shopping checklist, record the manufacturer’s stated frequency, any combinations it warns against, and whether your existing products overlap. A daily-use claim does not establish that everyone needs a daily exfoliation step. Do not increase frequency to finish a bottle faster.

Read warnings alongside the front-label percentage

The Ordinary’s toner page includes an AHA sunburn warning: the formula may increase sun sensitivity. Its directions call for sunscreen, protective clothing and limiting sun exposure during use and for a week afterwards. That warning is part of evaluating this particular product, not optional fine print.

A percentage can help identify a named formula, but it does not by itself answer whether that product fits your routine. Before comparing percentages across bottles, compare what each product actually is, where it is intended to be used, and its instructions. We are not ranking formulas by strength or promising a result.

Make a five-line comparison before buying

For each option, note: exact name and size; scrub, cleanser or leave-on format; directions and warnings; the step it would replace or add; and total delivered price. Use the same size when comparing sellers, and include shipping rather than relying on a large discount badge.

Check the current Australian brand page against the retailer listing. If the variant or instructions do not match, resolve that before ordering. Start with information rather than a multi-product bundle: an extra bottle is not automatically better value, and choosing not to add a new step is a valid outcome.
