Good skin does not require a cabinet full of expensive products. In fact, many skin problems come from doing too much or skipping the basics. Here are the most common skincare mistakes and how to fix them.

1. Skipping sunscreen in winter or on cloudy days

UV rays reach your skin year-round and reflect off snow. Daily broad-spectrum SPF 30 or higher is the single best step to prevent premature aging and reduce skin cancer risk.

2. Over-exfoliating

Scrubs, acids and peels used too often damage the skin barrier, causing redness, stinging and breakouts. Most people need exfoliation only one to three times a week.

3. Using too many active ingredients at once

Combining retinoids, vitamin C, exfoliating acids and benzoyl peroxide all at once can irritate skin. Introduce one new active at a time and give it several weeks.

4. Washing with hot water

Hot water strips natural oils. Use lukewarm water, especially in winter.

5. Sleeping in makeup

Makeup, sunscreen and pollution clog pores overnight. Cleanse every evening, double cleansing if you wore sunscreen or makeup.

6. Picking at blemishes

Squeezing pimples can push bacteria deeper and lead to scars and dark spots. Use a spot treatment or a hydrocolloid patch instead.

7. Skipping moisturizer on oily skin

Dehydrated skin can produce more oil. Choose a lightweight, non-comedogenic moisturizer.

8. Forgetting your neck, chest and hands

These areas show sun damage too. Extend your routine and sunscreen beyond your face.

9. Changing products too quickly

Most products need four to twelve weeks to show results. Give a routine time before switching.

10. Ignoring lifestyle

Sleep, hydration, a balanced diet and not smoking all affect your skin.
