Skincare myths — and what the evidence actually says

Oily skin doesn't need moisturizer.

Oily skin still needs moisture — skipping it makes things worse.

You should feel a tingle or burn — that means it's working.

Burning or stinging is your skin telling you something is wrong, not right.

Natural ingredients are automatically safer than synthetic ones.

Natural doesn't mean safe. Synthetic doesn't mean harmful.

Retinol thins your skin over time.

Retinol actually thickens the dermis with long-term use.

You need to wash your face twice in the morning.

For most people, water or a light rinse is enough in the morning.

More products = better results.

Overloading your routine reduces the effectiveness of each product.

Vitamin C and Niacinamide cancel each other out.

They're safe to use together. The cancellation theory is based on outdated research.

Your skin type is permanent and never changes.

Skin type can shift with age, season, climate, diet, hormones, and medication.

Expensive skincare always works better than cheap skincare.

Price reflects branding and packaging more than ingredient quality.

Pores open and close with hot and cold water.

Pores don't have muscles. They can't open or close.

SPF is only necessary on sunny days.

UVA rays are present year-round, rain or shine, indoors near windows.

Coconut oil is a good moisturizer for the face.

Coconut oil is highly comedogenic and clogs pores on most skin types.
