With so much information available online, it can be hard to separate fact from fiction when it comes to skincare. To clear up the confusion, we've consulted with dermatologists to debunk three of the most persistent skincare myths.

Myth #1: You Don't Need Moisturizer if You Have Oily Skin

This is one of the most common misconceptions. Many people with oily skin skip moisturizer, fearing it will make their skin even greasier. However, the opposite is often true. When you strip oily skin of its natural moisture (often with harsh, drying cleansers), it can go into overdrive and produce even more oil to compensate. The key is to choose the right moisturizer. Look for lightweight, oil-free, non-comedogenic formulas that will hydrate your skin without clogging pores.

Myth #2: The Higher the SPF, the Better the Protection

While a higher SPF does offer more protection, the increase is marginal once you get above SPF 30. For example:

  • SPF 15 blocks about 93% of UVB rays.
  • SPF 30 blocks about 97% of UVB rays.
  • SPF 50 blocks about 98% of UVB rays.
  • SPF 100 blocks about 99% of UVB rays.

More important than a super-high SPF is applying it correctly and consistently. Most people don't apply enough sunscreen to achieve the stated SPF level. You should use about a shot glass full for your body and a nickel-sized dollop for your face, and reapply every two hours, or more often if you're swimming or sweating.

Myth #3: Natural or "Clean" Ingredients Are Always Better

The terms "natural" and "clean" are not regulated in the beauty industry, so they can mean different things to different brands. While many natural ingredients are beneficial, not all synthetic ingredients are bad, and not all natural ingredients are safe. For example, essential oils and plant extracts can be potent allergens for some people. The effectiveness and safety of an ingredient depend on its chemical composition, concentration, and how it's formulated, not just whether it's derived from nature or a lab. It's more important to focus on evidence-based ingredients and formulations that are proven to be effective and suitable for your skin type.
