Skincare is one of the most talked-about topics in the beauty industry, yet misconceptions and myths continue to mislead consumers. With an overwhelming amount of information online, it’s easy to fall for beauty trends that may not actually benefit your skin—or worse, may harm it.
From the idea that natural is always better to the belief that you don’t need sunscreen on cloudy days, some myths have been around for decades. In this article, we will debunk the most common skincare myths, relying on scientific research and dermatologist insights to provide you with evidence-based skincare knowledge.
1. Myth: You Don’t Need Sunscreen on Cloudy or Cold Days
The Truth: UV Rays Penetrate Through Clouds and Glass
One of the biggest skincare misconceptions is that sunscreen is only necessary on sunny days. In reality, up to 80% of UV rays penetrate clouds (Skin Cancer Foundation). This means that even on overcast or cold days, your skin is still exposed to harmful radiation.
- UVA rays (responsible for aging) and UVB rays (responsible for burning) are always present.
- Even indoor light and screens emit blue light, which can contribute to premature aging.
- Solution: Apply a broad-spectrum SPF 30 or higher every day, regardless of weather conditions.
2. Myth: Oily Skin Doesn’t Need Moisturizer
The Truth: Skipping Moisturizer Can Make Oiliness Worse
Many people with oily skin believe they don’t need moisturizer, fearing it will make their skin shinier or cause breakouts. However, stripping the skin of moisture can actually trigger excess oil production, leading to more clogged pores and acne.
- Dehydrated skin compensates by producing more sebum.
- Using an oil-free, non-comedogenic moisturizer helps maintain skin hydration without clogging pores.
- Look for ingredients like hyaluronic acid and niacinamide, which hydrate without feeling heavy.
3. Myth: Natural Ingredients Are Always Better
The Truth: Natural Doesn’t Always Mean Safe or Effective
The term “natural” in skincare is often misleading—just because an ingredient is derived from nature doesn’t mean it’s safe for the skin.
- Lemon juice, apple cider vinegar, and baking soda are frequently recommended in DIY skincare, yet they can disrupt the skin barrier, cause irritation, and increase sun sensitivity.
- Conversely, lab-formulated ingredients like retinol, peptides, and ceramides have been extensively tested and shown to be effective in treating skin concerns.
- Solution: Always choose science-backed products rather than assuming that “natural” is superior.
4. Myth: Pores Can Open and Close
The Truth: Pores Don’t Have Muscles
One of the most common beauty myths is that hot water or steam can “open” pores and cold water can “close” them. However, pores do not have muscles and cannot change size.
- Steam can soften debris inside pores, making extraction easier, but it doesn’t physically “open” them.
- Cold water or toners may make pores appear smaller temporarily by reducing inflammation but do not permanently shrink them.
- Solution: If you want to minimize the appearance of pores, use ingredients like salicylic acid (BHA) and retinoids that help keep them clear and refined.
5. Myth: You Should Exfoliate Every Day for Clear Skin
The Truth: Over-Exfoliation Damages the Skin Barrier
Exfoliation helps remove dead skin cells, but doing it too often can cause more harm than good. Over-exfoliating can:
- Strip the skin of its natural oils, leading to inflammation, redness, and sensitivity.
- Weaken the skin barrier, making it prone to breakouts and dehydration.
- Cause micro-tears if using harsh physical scrubs.
Solution: Stick to 2-3 times per week, using gentle chemical exfoliants like AHAs (glycolic acid) or BHAs (salicylic acid) instead of harsh scrubs.
6. Myth: Acne Is Only a Teenage Problem
The Truth: Adult Acne Is Common and Treatable
Many people assume that acne only affects teenagers, but adult acne is a widespread issue. Factors like hormonal imbalances, stress, diet, and skincare products can trigger breakouts at any age.
- Hormonal fluctuations (especially in women) can cause cystic acne on the jawline and chin.
- Comedogenic skincare and makeup products can clog pores and trigger breakouts.
- Solution: Use non-comedogenic skincare, manage stress, and consider acne-fighting ingredients like benzoyl peroxide, niacinamide, and salicylic acid.
7. Myth: The More Expensive a Product, the Better It Works
The Truth: Price Doesn’t Always Equal Quality
Luxury skincare brands often market their products as being more effective, but price does not always indicate quality.
- Many affordable drugstore products contain the same active ingredients as high-end brands.
- What matters most is the formula, concentration of active ingredients, and skin compatibility.
- Solution: Look at ingredient lists, not just branding. A $15 niacinamide serum can be just as effective as a $100 one.
8. Myth: Drinking More Water Clears Your Skin
The Truth: Hydration Is Important, But It Won’t Cure Acne
While staying hydrated is essential for overall skin health, simply drinking more water won’t clear acne, fade wrinkles, or replace a skincare routine.
- Water helps maintain skin elasticity and function, but breakouts and aging are more influenced by hormones, skincare products, and sun exposure.
- Solution: Combine hydration with a proper skincare routine that includes sun protection, moisturizers, and targeted treatments.
