Scrub or acid?

Scrub or acid exfoliant?

Both remove dead skin cells, in very different ways. Here's how they compare, which suits your skin, and how to use either one safely.

The short answer
1Scrubs work physically. Fine grains lift dead cells as you massage. Smoother straight away. 2Acids work chemically. They loosen the bonds between dead cells over days or weeks. 3Choose by skin and preference. Many people use a gentle scrub on the body and an acid on the face. 4Don't combine them on the same day. Double exfoliation is the fastest route to irritation.

Exfoliation has two camps: people who love the instant smoothness of a scrub, and people who swear by acids. Both are right, for different skin and different reasons.

01How each works

A scrub contains fine grains, such as volcanic sand, in a cream or gel base. As you massage, the grains help lift loose dead cells from the surface. You're in control of pressure and time, and the result is immediate.

An acid exfoliant uses alpha hydroxy acids (AHAs) such as glycolic or lactic acid, or beta hydroxy acid (salicylic acid). They loosen the bonds that hold dead cells together, so they shed more easily. Results build gradually, and strength depends on the acid, its percentage and the formula's pH.

02Pros and cons

Scrub Acid exfoliant
Speed Instant smoothness Gradual
Control You decide pressure and time Set by the formula
Body use Easy on large areas Often separate products
Sun sensitivity No added sensitivity from grains AHAs can increase it
Common mistakes Pressing too hard, using daily Too strong, too often, mixing actives

03Which suits you

✓Rough elbows, knees, legs: a gentle scrub is quick and satisfying.
✓Dull facial skin, uneven tone: a mild acid often suits better over time.
✓Sensitive or reactive skin: a very gentle scrub once a week, or a mild lactic acid product; patch test either.
✓Active acne, eczema or rosacea flares: skip scrubs on affected areas and ask a pharmacist or dermatologist.

Our Icelandic Volcano Face & Body Scrub is a gentle scrub for face and body. It contains a little lactic and citric acid, but only to adjust the pH; it isn't an acid exfoliant. The full ingredient breakdown is in the research behind it.

04Using both, safely

You can use a scrub and an acid in the same week, just not on the same day on the same area. A simple pattern: scrub on Monday and Thursday, acid on Tuesday or Saturday, moisturiser every day. If skin stings, looks shiny or feels tight, cut back. How often should you exfoliate? has schedules by skin type.

05Your questions, answered

Is a scrub worse for your skin than acids?

Not inherently. Fine grains, light pressure and two or three uses a week are gentle. Harsh particles and daily scrubbing are the problem.

Can I use a scrub and an AHA on the same day?

It's best not to. Alternate days to avoid irritation.

Which is better for body skin?

A scrub is usually quicker and easier on large areas like legs and arms.
