Skincare Myths: What the Science Actually Says

Misinformation often relies on fear, dramatic language, a single small study or before-and-after photos. Good advice comes from consistent evidence and people with real training in skin.

Ask a few questions: Who is making the claim, and are they selling something? What is the evidence, and was it done in people or only in a lab? Does it sound too good to be true?

Ingredients are not dangerous just because they have long chemical names, and natural does not always mean safe. Poison ivy and many essential oils are natural, and they are common causes of skin reactions.

Many viral trends come and go without evidence. Some, like ear seeding facials or extreme longevity routines, are mostly harmless but unproven. Others can irritate or damage the skin.

Be especially careful with trends that put household products on the face, use high-strength acids or involve DIY procedures. When a trend promises dramatic results with no downside, be skeptical.

Some popular hacks can work when used correctly, but the details matter. Using a product in a way it was not designed for can increase irritation.

Whether a product works depends on its active ingredients, their strength, how stable the formula is and how consistently you use it. Price and popularity tell you very little.

Vitamin C serums can oxidize and turn orange or brown over time, which means they have lost much of their effect. Store them away from light and heat, and replace them when they change colour.

Retinol is one of the most misunderstood ingredients. It does not thin the skin over time, and with a slow start most people can tolerate it.

Many common rumours are half-truths. You cannot shrink pores permanently, but you can make them look smaller. Drinking water is good for your health, but it does not cure dry skin on its own.

Pregnancy is a good time to check your products. Retinoids are generally avoided during pregnancy, while sunscreen, moisturizers and azelaic acid are usually considered safe. Check with your doctor.

Alternative therapies can be appealing, but they rarely have the evidence of proven treatments, and delaying effective treatment can make skin conditions harder to manage.
