Why Skincare Is Full of Myths
Skincare is a multi-billion dollar global industry built partly on storytelling, aspirational marketing, and word-of-mouth. Social media accelerates the spread of unverified claims, influencer endorsements, and DIY "hacks" that are sometimes harmless, sometimes actively damaging.
This guide addresses 20 of the most common skincare myths circulating in Nepal and globally, replacing them with what dermatology evidence actually says.
Sunscreen Myths
Myth 1: "You don't need sunscreen on cloudy days"
Reality: Up to 80% of UV radiation penetrates cloud cover. Clouds block visible light (which is why you feel "cooler" outdoors on a cloudy day) but do not block the UVA and UVB radiation that damages skin and causes hyperpigmentation and skin cancer. In Nepal's mountain and high-altitude regions, UV intensity is significantly higher than at sea level — and cloud cover there can be highly variable.
UVedge SPF 50 Gel should be applied every morning regardless of cloud cover or season.
Myth 2: "People with dark skin don't need sunscreen"
Reality: People with darker skin (Fitzpatrick IV–VI) have more melanin, which provides some intrinsic UV protection (roughly SPF 2–13), but this is nowhere near adequate. UV damage in darker skin types manifests differently — as post-inflammatory hyperpigmentation, uneven tone, and melasma rather than sunburn. People with darker skin are also at risk for UV-induced DNA damage and collagen degradation. Sunscreen is essential for all skin tones.
Myth 3: "Higher SPF means I can apply once and forget it"
Reality: SPF measures the degree of UVB protection per application, not duration of protection. SPF 100 does not last twice as long as SPF 50. Sunscreen effectiveness degrades through sweat, sebum, friction, and photodegradation. Regardless of SPF, reapplication every 2 hours of sun exposure is required. UVedge SPF 50 Gel makes daily reapplication easy without a heavy feel.
Myth 4: "Makeup with SPF is sufficient protection"
Reality: See FAQ above. SPF in makeup is not applied in sufficient quantity to deliver the labelled protection. Always apply a dedicated sunscreen underneath makeup.
Cleansing Myths
Myth 5: "The tighter/more squeaky-clean your skin feels after washing, the better"
Reality: That tight, squeaky feeling after washing indicates that the skin's natural moisturising factors (NMFs) and lipids have been stripped — it is a sign of barrier damage, not cleanliness. Over-stripping the skin causes reactive sebum production (worsening oiliness), barrier dysfunction (worsening dryness and eczema), and increased sensitivity. Use a gentle, pH-balanced cleanser like Moisoft Cleanser that removes impurities without stripping.
Myth 6: "Washing your face more often clears acne"
Reality: Acne is not caused by surface dirt. Over-washing dries and irritates the skin, disrupts the microbiome, and can increase inflammation — worsening acne. Twice daily cleansing is the recommended maximum for most skin types. For oily or acne-prone skin, a salicylic acid-based cleanser addresses the oil-in-follicle issue more effectively than wash frequency.
Moisturiser and Hydration Myths
Myth 7: "Oily skin doesn't need moisturiser"
Reality: See FAQ above. Oiliness and hydration are different properties. Dehydrated oily skin produces more sebum reactively. Use a lightweight, non-comedogenic moisturiser like Moisoft Lotion.
Myth 8: "Coconut oil is a good face moisturiser for all skin types"
Reality: Coconut oil is highly comedogenic (it scores 4/5 on the comedogenicity scale). It is excellent for hair care but clogs pores when used regularly on the face, particularly for acne-prone or combination skin. Its antimicrobial properties do not compensate for its tendency to worsen follicular congestion.
Active Ingredient Myths
Myth 9: "Natural ingredients are always safer than synthetic ones"
Reality: See FAQ above. Evidence and formulation determine safety, not source. Poison ivy is natural; paracetamol is synthetic. Both matters of evidence, not origin.
Myth 10: "You should feel your skincare 'working' — tingling means it's effective"
Reality: Tingling, burning, or stinging sensations are signs of irritation, not efficacy. Active ingredients like vitamin C, AHAs, and retinol can cause a mild initial sensation as the skin adapts, but persistent stinging indicates concentration, formulation, or application method issues. Effective skincare can be completely sensation-free.
Myth 11: "You can't use vitamin C and niacinamide together"
Reality: This myth originated from a misunderstood 1960s study showing that niacin (not niacinamide) and vitamin C can form a yellow compound. Modern formulated niacinamide and vitamin C products can be layered without issue. They target different pigmentation pathways and complement each other. See our full guide: How to Use Vitamin C in Skincare.
Myth 12: "SPF 30 is half as effective as SPF 60"
Reality: SPF numbers are not linear. SPF 30 blocks approximately 97% of UVB; SPF 50 blocks ~98%; SPF 100 blocks ~99%. The difference between SPF 30 and SPF 50 is marginal, and the gap above SPF 50 is negligible in real-world use. Consistent daily application of SPF 50 matters far more than the SPF number above 50.
Acne Myths
Myth 13: "Toothpaste dries out spots"
Reality: Toothpaste contains ingredients like fluoride, detergents, and abrasives that are not designed for facial skin. It dries and irritates the surrounding skin, causing redness and flaking without meaningfully affecting the acne lesion itself. Benzoyl peroxide or salicylic acid spot treatments are evidence-based alternatives.
Myth 14: "Chocolate and greasy food cause acne"
Reality: The relationship between diet and acne is complex. High-glycaemic index foods and dairy (particularly skim milk) have some evidence linking them to acne exacerbation. Chocolate in moderation and most "greasy" foods do not have direct causal links to acne in the evidence base. The causes of acne are primarily sebum overproduction, follicular keratinisation, and bacterial proliferation — not the grease from food touching your face.
Myth 15: "Sun exposure helps clear acne"
Reality: Short-term UV exposure can reduce inflammation and temporarily dry skin, creating a brief appearance of improvement. Long-term, UV exposure worsens acne and causes post-inflammatory hyperpigmentation from healing spots, increases skin damage, and accelerates ageing. It is not a recommended acne treatment. See Hormonal Acne Causes and Treatment.
Anti-Aging Myths
Myth 16: "Eye cream is essential — you can't use regular moisturiser around the eyes"
Reality: The periorbital skin is thinner and more sensitive, and ingredients safe for the cheek may cause irritation there (especially retinoids). However, a fragrance-free, gentle moisturiser (like Moisoft Lotion) applied gently to the eye area works adequately for most people. Dedicated eye creams tend to be formulated with gentler, more hydrating ingredients optimised for that skin area, but they are not obligatory for everyone.
Myth 17: "Your skin 'gets used to' products and they stop working"
Reality: With some active ingredients (retinoids, AHAs), your skin does adapt — the adaptation is called tachyphylaxis and is more relevant for prescription treatments than OTC actives. For most skincare products, if they seem less effective over time, the more likely explanation is that the skin's condition has changed (season, hormones, age) or the ingredient was never substantially effective to begin with. A stable, evidence-based routine that is working should be continued.
Myth 18: "Anti-aging creams can erase existing wrinkles"
Reality: Retinoids can improve the appearance of fine lines by increasing cell turnover and stimulating collagen production — but results are modest and require months of consistent use. No OTC product removes deep, established wrinkles. Interventions like injectable treatments (Botox, fillers) achieve more significant visible results but are medical procedures. Consistent SPF use is the single most effective intervention for preventing new signs of photoageing.
DIY and "Hack" Myths
Myth 19: "Lemon juice is a good DIY brightening treatment"
Reality: Lemon juice is acidic (pH 2–3, compared to skin's pH 4.5–5.5) and contains phototoxic furanocoumarins (especially psoralen) that make skin dramatically more sensitive to UV. Applying lemon juice to facial skin and going outdoors can cause phytophotodermatitis — severe dark patches that are harder to treat than the original hyperpigmentation. Use evidence-based brightening actives: tranexamic acid, niacinamide, kojic acid, vitamin C.
Myth 20: "Pores open and close with hot and cold water"
Reality: Pores do not have muscles and cannot open or close. Pore size is determined by genetics and sebum production. Hot water can soften the sebum in pores (making manual extraction easier during a facial) and cold water can cause temporary vasoconstriction that makes pores appear slightly smaller — but neither "opens" or "closes" pores in a meaningful way. Regular exfoliation with salicylic acid keeps pores clear by dissolving the sebum congestion inside them.
Summary
Evidence-based skincare is simple: a gentle cleanser, a moisturiser, a broad-spectrum SPF 50, and targeted actives for your specific concerns. Most viral skincare trends and DIY remedies either lack evidence or actively cause harm. When in doubt, ask a dermatologist rather than trusting influencer content.
