Age BeautifullySkincare advice travels fast, and a lot of it is half true at best. These ten beliefs come up again and again. Here's what the evidence says about each one, so you can spend less and worry less.
Sun protection
Myth
You don't need sunscreen on cloudy days or in winter.
Fact
UV light reaches your skin on cloudy days and in winter, and UVA can pass through window glass. The American Academy of Dermatology recommends sunscreen even then.
Myth
A higher SPF means you can apply less or reapply less often.
Fact
Most people already apply too little. Whatever the SPF, use enough, and reapply every two hours outdoors and after swimming or sweating.
Myth
People with darker skin don't need sunscreen.
Fact
Deeper skin tones have more natural protection, but they can still burn, develop skin cancer and experience sun-related darkening. Sun protection matters for every skin tone.
Products and prices
Myth
If it tingles, it's working.
Fact
Stinging and burning are signs of irritation, not effectiveness. Stop products that sting or burn, unless a dermatologist prescribed them and knows how your skin is reacting.
Myth
Natural products are always gentler and safer.
Fact
"Natural" has no regulatory definition for cosmetics. Many plant extracts and essential oils can irritate skin or cause allergies. What matters is the specific ingredient and how your skin responds.
Myth
Expensive products work better.
Fact
Price reflects packaging, branding and marketing as much as formulation. Well-formulated products exist at every price point.
Myth
Collagen creams add collagen to your skin.
Fact
Collagen molecules in creams are too large to replace the collagen in your skin's deeper layer. They can moisturize the surface, but they don't rebuild collagen.
Routines and habits
Myth
Oily skin doesn't need moisturizer.
Fact
Oily skin can still be dehydrated, especially when harsh products strip it. A light, non-comedogenic moisturizer often helps it feel more balanced.
Myth
Drinking more water will hydrate dry skin.
Fact
The evidence for drinking extra water to improve skin is limited, and any benefit seems greatest in people who drink very little. Gentle cleansing and moisturizer usually help dry skin most.
Myth
Your skin needs a detox.
Fact
Your liver and kidneys remove waste from your body continuously. There's no good evidence that detox masks, teas or cleanses improve your skin.
Most of the good news is quiet: daily sunscreen, gentle cleansing, a moisturizer your skin likes, and one well-chosen active if you want one. The rest is detail, and a great deal of it is marketing.
