Think pores “open” with steam? Think oily skin doesn’t need moisturizer? Here are the top 5 beauty myths people still believe—debunked by science.
Beauty Myths People Still Believe: Science vs. Skincare Damage
The number of harmful beauty myths people still believe is staggering, and following them blindly is often what wrecks your moisture barrier in the first place.
If you listened to every piece of “skincare advice” on the internet, you’d probably be washing your face with baking soda and drying it with a hair dryer. From “shrinking” pores to “drying out” pimples, bad advice is everywhere.
You’ve likely heard that steam “opens” your pores. Or maybe that oily skin needs to be punished with harsh alcohols. Stop. Your face is a biological organ, not a kitchen floor.
When we dig into the most common myths, we find they are mostly old wives’ tales that refuse to die. Marketing loves them because they sell products. Your skin, however, hates them.
Let’s look at the hard facts (verified by the [[American Academy of Dermatology]]): Your skin does not breathe, your pores do not have muscles, and “natural” does not always mean safe.

Quick Answer: Top 5 Myths Debunked
Myth 1: “Steam opens your pores.”
Fact: Pores are holes, not doors. They have zero muscles. Steam just softens the gunk inside.
Myth 2: “Oily skin doesn’t need moisturizer.”
Fact: False. Dehydrated skin panics and produces more oil to compensate.
Myth 3: “Natural ingredients are better.”
Fact: Poison Ivy is natural. Arsenic is natural. “Natural” tells you nothing about safety.
Myth 4: “You can shrink your pores permanently.”
Fact: Pore size is genetic. You can’t shrink them any more than you can shrink your shoe size.
Myth 5: “SPF is only for sunny days.”
Fact: UVA rays (the ones that age you) cut right through clouds and glass, 365 days a year.
At Glimpsera, we prefer chemistry over fairytales. Here is the forensic breakdown of why you need to stop believing the hype.
Myth #1: “Hot Water Opens Pores, Cold Water Closes Them”
This is one of the most persistent lies in the beauty world. The Science: Pores are just the opening of a hair follicle. They do not have sphincter muscles. They physically cannot open or shut. The Reality: Hot water or steam softens the hardened oil (sebum) inside the pore, making it looser and easier to extract. That’s it. Cold water might constrict the blood vessels nearby, making your skin look tighter for about five minutes, but the pore size itself? It hasn’t changed a bit. 
What to do instead: Cleanse with lukewarm water and use a gentle chemical exfoliant (BHA) to keep pores clear.
Myth #2: “If It Stings, It’s Working”
We have been conditioned to think that pain equals progress. If it burns, it must be killing the bacteria, right? The Science: Wrong. Stinging is usually your nerves screaming that your barrier is under attack. The Reality: If your toner or mask stings, you are likely causing inflammation. Chronic inflammation is essentially a fast-track ticket to collagen breakdown (aging) and hyperpigmentation. The Fix: If you feel the burn, wash it off immediately. (If you’ve already fried your face this way, switch to a [[routine for dry sensitive skin]] to rebuild the wall before doing anything else).
Myth #3: “Oily Skin Should Be Dried Out”
Teens are practically trained to attack grease with harsh alcohols. The Science: Your skin demands a balance of oil and water. When you strip away 100% of the oil, your sebaceous glands freak out. They think the skin is drying out, so they go into overdrive. The Reality: Drying out oily skin makes it oilier in the long run. It’s a trap. You actually need to hydrate it with water-based products so it feels safe enough to stop pumping out excess grease. (For a smarter approach, check our [[simple routine for oily acne-prone skin]] which hydrates without clogging).
Myth #4: “Natural is Always Safe”
“Chemical-free” is a nonsense marketing term (water is a chemical). The Science: Plenty of natural ingredients—like Lemon Juice, Unfiltered Essential Oils, or Baking Soda—are incredibly harsh, unstable, and allergenic. The Reality: A lab-created molecule is often purified specifically to remove allergens. A “natural” extract varies by crop and often brings a host of irritants along with it. Think of it this way: Poison Ivy is 100% organic and natural. That doesn’t mean you should rub it on your face. What to do instead: Look for ingredients labeled “hypoallergenic” or “tested for sensitive skin,” regardless of whether they are natural or synthetic.
Myth #5: “Scrubbing Blackheads Makes Them Go Away”
In most cases, you cannot scrub a pore clean, no matter how hard you press. The Science: Blackheads sit deep inside the pore shaft. A physical scrub (like those apricot pits or sugar scrubs) only scratches the surface layer of skin. The Reality: Aggressive scrubbing usually just tears the skin surface, spreading bacteria around. The only way to actually remove a blackhead is to dissolve the glue holding it together chemically. (To understand exactly which ingredient dissolves these plugs, read [[What Salicylic Acid really treats]]).
Real-Life Micro-Story: The “Toothpaste” Regret
“I had a massive pimple right before a date. My mom told me the old trick: put toothpaste on it to ‘dry it out.’ I woke up with a chemical burn the exact shape of the toothpaste smear. The pimple was still there, but now it was surrounded by a dark, crusty ring of burnt skin. The Lesson: Toothpaste is for enamel, not epidermis. The menthol and fluoride are severe irritants for skin.”
Final Thoughts: Be Skeptical
The list of beauty myths people still believe is long because simple lies are easier to sell than complex science. Your skin is resilient, but it is not indestructible. Treat it with gentle consistency, not aggressive “hacks” you found on a forum.
If a tip sounds too good (or too painful) to be true, it probably is.

Frequently Asked Questions
Does drinking water hydrate your skin?
Only if you are severely dehydrated. While water is essential for keeping you alive, your skin is the last organ to receive hydration from what you drink. No amount of water will fix dry skin if you aren’t using a topical moisturizer to seal it in.
Do pores get larger with age?
Sadly, yes. As we age, we lose collagen and elastin—the structural scaffolding of the skin. Without this support, the skin around the pore starts to sag, making the opening appear larger (stretched out), even if the pore itself hasn’t grown.
Is expensive skincare better?
Not necessarily. Half the time, you are paying for the jar and the celebrity endorsement. Many affordable brands (like The Ordinary or CeraVe) use the exact same active ingredients (Retinol, Niacinamide) as the $100 creams, often at effective clinical concentrations.
