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.
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
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.
