Quick answer: Good skincare is usually less dramatic than viral advice. Oily skin can need moisturiser; burning is not proof that a product works; and sunscreen matters when you are exposed to daylight. Here are nine myths worth leaving behind.
At Scientifique, we believe in choosing products for a reason. These tips are general education, not a diagnosis or a replacement for individual advice from a dermatologist or pharmacist.
Myth 1: Oily skin does not need moisturiser
Reality: Oily skin can still benefit from a suitable moisturiser. Look for a comfortable texture and, if you are acne-prone, consider products labelled non-comedogenic. You do not need to use a very heavy cream to keep skin hydrated. The Anua Birch Moisture Boosting Cream is one option to assess against your preferences and ingredient sensitivities.
Myth 2: A burning sensation means the active is working
Reality: Stinging, burning or persistent tingling can signal irritation. Stop a new product that causes a significant reaction and seek advice if symptoms persist or are severe. Patch-test new skincare before applying it widely, especially if your skin is reactive.
Myth 3: The more you exfoliate, the faster you glow
Reality: Exfoliation is not necessary for everyone, and overdoing it can cause redness and irritation. If you use an AHA or BHA, follow the label, start cautiously and avoid stacking multiple exfoliating products in one routine. A gentle basic routine often makes more sense when skin is already irritated.
Myth 4: Acne-prone skin should be dried out
Reality: Harsh scrubbing and repeatedly stripping the skin can irritate it. Use a gentle cleanser and an appropriate moisturiser. If you have painful, deep or scarring acne, a dermatologist can help you choose treatment beyond cosmetics. A product such as COSRX Acne Master Patches may protect an individual blemish from picking, but is not a cure for acne.
Myth 5: Sunscreen is only for beach days
Reality: When you go outside, UV exposure is not limited to holidays. Choose broad-spectrum SPF 30 or higher, apply according to the label and reapply around every two hours outdoors or after swimming or sweating. For an everyday option, browse Beauty of Joseon Relief Sun SPF 50+.
Myth 6: SPF 50 means you never need to reapply
Reality: Higher SPF does not make sunscreen a one-time application for a whole outdoor day. Reapplication, shade and sun-protective clothing still matter.
Myth 7: “Natural” always means irritation-free
Reality: A product can irritate you regardless of whether an ingredient is described as natural or synthetic. Read the ingredient list, consider your known allergies and test a new product on a small area first.
Myth 8: More serums make a routine better
Reality: Each extra active adds complexity and may make it harder to identify what is helping or irritating. Start with cleansing, moisturising and sun protection. Add one targeted product at a time for a specific concern.
Myth 9: Results should be visible in a few days
Reality: Skincare is not an overnight makeover. Some products make skin feel hydrated quickly, but visible changes for concerns such as texture or uneven tone take time and vary by person. Follow the label and be wary of guaranteed transformation claims.
A better rule of thumb
Ask three questions before buying: What concern am I addressing? Does this fit with what I already use? Will I use it consistently? If you need a simple base, start with a gentle cleanser, suitable moisturiser and sunscreen, then choose optional treatments deliberately.
