Aspirin is an effective topical treatment.

This is another case of: If it's not meant for your face, don’t put it there.

Unless your dermatologist advises otherwise, leave your aspirin in the medicine cabinet.

You should spend more for better skincare.

Expensive doesn’t always equal better quality, and rare ingredients aren’t necessarily more effective.

Often, there isn’t scientific evidence that these ingredients are, in fact, worth it. In skincare, a higher price tag really doesn’t guarantee better quality.

OILY SKIN? STOP MOISTURIZING.

This is a common misconception, but when you don’t moisturize oily skin (or any skin type), it compensates by producing even more oil in a vicious cycle that can lead to more breakouts.

All skin types need to stay moisturized in order to maintain a strong barrier, which is also what helps fend off acne-causing bacteria in the first place.

If you have oily skin, find a moisturizer formulated specifically for your skin type.

HOT WATER OPENS UP PORES FOR A BETTER CLEAN.

First of all, pores can’t open and close. Second of all, hot water can potentially strip your skin of essential oils.

Your best bet: Always wash your face with lukewarm — not hot — water. If your skin is red after rinsing, the water is probably too hot.
