Should You Apply Skincare Before or After Brushing Your Teeth?

A small, easy-to-overlook detail in most routines: whether you brush your teeth before or after your skincare steps.

It seems trivial, but there’s a real, physical reason one order makes more sense than the other.

Brush first, then wash your face

The main reason is straightforward.

Toothpaste residue, even a small amount left around your mouth or on your fingers, contains ingredients like sodium lauryl sulfate and fluoride that can irritate skin, particularly for anyone with sensitive skin, rosacea, or acne-prone areas near the mouth.

If you wash your face before brushing, that residue has nowhere useful to go except onto skin you just cleaned.

What’s actually in toothpaste that causes this

Sodium lauryl sulfate, a foaming agent common in many toothpaste formulas, is a known contact irritant for some people when it touches skin outside its intended use.

Whitening or tartar-control toothpastes often carry a higher pH than plain formulas, which can further disrupt skin’s naturally slightly acidic surface if residue lingers there.

Neither of these ingredients is dangerous in the context they’re designed for, inside your mouth, briefly.

The issue is specifically about unintended, repeated skin contact from residue.

Does this actually cause breakouts

For some people, yes, particularly around the mouth and chin, areas already prone to irritation from other sources like lip products or food contact.

If you’ve noticed small bumps or irritation specifically clustered around your mouth without an obvious other cause, toothpaste residue transfer is a reasonable thing to rule out.

The practical routine order

Brush your teeth first, rinse your mouth thoroughly, and then wash your face as the actual first skincare step.

This way, any toothpaste residue gets rinsed away during your normal face-washing step rather than sitting on freshly cleansed skin with nothing to remove it.

What if you brush your teeth midday, separate from your routine

The same logic applies loosely, though it matters less outside your actual skincare routine.

If you notice irritation after a midday brushing, a quick rinse of your mouth and chin area afterward addresses the same residue concern without requiring a full skincare reset.

Does toothpaste type make a difference

Yes, somewhat.

A toothpaste without sodium lauryl sulfate, sometimes labeled SLS-free, reduces the irritation risk if residue does end up on skin, though thorough rinsing after brushing remains the more reliable fix regardless of which toothpaste you use.

Is this really worth changing your routine for

If you’ve never noticed any irritation near your mouth, this is a low-stakes detail that may not change anything for you personally.

If you do deal with recurring irritation, bumps, or sensitivity in that specific area, this is a genuinely easy, cost-free adjustment worth testing before assuming a skincare product is the cause.

See the correct skincare routine order for how this fits into the broader sequence of steps, since it’s a small addition to an otherwise unrelated routine question.

A small change worth testing

Brushing your teeth before washing your face, rather than after, avoids leaving toothpaste residue sitting on freshly cleansed skin, which can genuinely irritate the area around your mouth for some people.

It’s a small, easy change, and while it won’t matter for everyone, it’s worth testing if you’ve noticed unexplained irritation specifically clustered near your mouth or chin.
