Skincare Myths That Dermatologists Wish Would Disappear

This myth has real consequences. While it's true that higher melanin levels provide a degree of photoprotection — research suggests darker skin may have a natural SPF equivalent of roughly 13 or lower — that falls far short of the SPF 30 or higher that dermatologists broadly recommend for daily use. UV-induced hyperpigmentation (dark spots and uneven tone) is actually among the most common skin concerns for people with deeper skin tones, and skin cancers, while statistically less frequent in darker-skinned individuals, are often diagnosed at later, harder-to-treat stages. Daily broad-spectrum SPF is a universal recommendation regardless of complexion.

This one is surprisingly widespread, possibly because some active ingredients — like certain chemical exfoliants — do produce a mild, temporary sensation when first introduced. But there's a meaningful difference between mild and brief versus persistent stinging or redness. The latter suggests your skin's protective barrier is being disrupted, not treated. Chronic irritation can worsen conditions like redness, sensitivity, and acne over time. If a product causes consistent discomfort, the right response is to discontinue it and, if needed, consult a dermatologist — not push through. Our guide to chemical exfoliants vs. physical scrubs explains what mild exfoliation should and shouldn't feel like.

Poison ivy is natural. So is lemon juice, which can cause a phototoxic reaction on skin exposed to sunlight. Meanwhile, synthetically derived hyaluronic acid and niacinamide are among the most well-tolerated and researched ingredients in dermatology. What matters is the ingredient itself, its concentration, how it's formulated, and how your individual skin responds to it. "Natural" has no standardized legal definition in U.S. cosmetics regulation, which means it functions more as a marketing signal than a safety guarantee. Fragrance — one of the most common causes of contact dermatitis — is often derived from natural plant sources.

Oil (sebum) and water are not the same thing. Skin can be oily on the surface while still being dehydrated — lacking adequate water content in the outer skin layer. When skin is dehydrated and stripped (from harsh cleansers or skipping moisturizer), it may respond by ramping up sebum production to compensate. Lightweight, non-comedogenic (non-pore-clogging) moisturizers are formulated precisely for oily and acne-prone skin types. Finding the right texture matters — gels and water-based lotions often work better than heavy creams for oily skin. Understanding your actual skin type and what it needs is the foundation of making the right call here.

Pores are follicle openings, not doors. They don't dilate in response to heat or contract in response to cold the way blood vessels do. What steam can do is soften the debris and sebum inside pores, making extraction or cleansing slightly easier — which may be where this myth originated. Cold water can temporarily reduce the appearance of redness or puffiness. But neither treatment changes the actual size of your pores. Consistent exfoliation, retinoids, and keeping pores clear of buildup are the approaches with the strongest evidence for minimizing their appearance over time.

Packaging, fragrance, brand positioning, and retail markup all contribute heavily to a skincare product's price. The active ingredients responsible for actual skin benefits — like retinol, niacinamide, glycolic acid, or ceramides — appear in products across a wide range of price points. Dermatologists frequently cite drugstore staples alongside luxury offerings when recommending effective options. That said, formulation quality and ingredient stability do matter, so reading ingredient lists carefully (not just price tags) is the more reliable approach. Cost is simply not a dependable proxy for performance.
