Top 7 Skincare Mistakes Dermatologists Wish You’d Stop Making
A Dermatologist’s Guide to Getting More Out of Your Routine
Skincare shouldn’t be complicated—but with TikTok trends, aggressive products, and conflicting advice everywhere, it’s no surprise that many patients feel overwhelmed. As a board-certified dermatologist, Dr. Victoria Moss, MD, FAAD sees the same preventable mistakes over and over.
Most people don’t need a 12-step routine. They need the right steps.
Below are the seven most common skincare mistakes—and dermatologist-approved solutions to get your skin thriving.
1. Over-Exfoliating (Especially With Scrubs)
Exfoliation can brighten skin and improve texture—but too much can damage your barrier, worsen acne, and cause redness.
Signs you’re over-exfoliating:
Burning or stinging
Flaking skin
Sudden breakouts
Tightness after washing
Fix it:
Limit exfoliation to 1–3 times per week
Choose chemical exfoliants over physical scrubs (AHA, BHA, PHA)
Add a barrier-repair moisturizer to restore balance
2. Using Too Many Active Ingredients at Once
Mixing retinoids, exfoliants, vitamin C, benzoyl peroxide, toners and scrubs is a recipe for irritation.
Fix it:
Use 1–2 targeted actives at a time and introduce new ones gradually.
Dr. Moss can design a streamlined routine customized to your skin type.
3. Skipping Sunscreen — or Applying It Incorrectly
The biggest skincare mistake? Not protecting your skin.
Mistakes that matter:
Only wearing SPF on sunny days
Relying on makeup with SPF
Not reapplying
Using too little sunscreen
Fix it:
Use broad-spectrum SPF 30+ daily
Reapply every 2 hours with outdoor exposure
Use a nickel-sized amount for the face
Sunscreen is the most powerful anti-aging product you own.
4. Sleeping in Makeup
Even “non-comedogenic” makeup can trap oil, bacteria, and pollution.
Fix it:
Double cleanse at night—especially if you wear foundation or sunscreen
Use micellar water + a gentle cleanser
This prevents breakouts, dullness, and irritation.
5. Treating Acne With Harsh Scrubs
Scrubbing acne makes inflammation worse.
Fix it with these over-the-counter options:
Use benzoyl peroxide for inflammatory acne - my absolute favorite is CeraVe’s BP 4% wash
Use salicylic acid for clogged pores
Apply retinoids at night for long-term prevention
If acne isn’t improving, it’s time for a dermatologist-led plan.
6. Avoiding Moisturizer Because Your Skin Is Oily
Oily skin still needs hydration. Dehydration can increase oil production.
Fix it:
Choose lightweight, non-comedogenic moisturizers with:
Hyaluronic acid
Squalane
Ceramides
Gel-based textures
Balanced skin behaves better.
7. Believing Marketing Claims Over Evidence
Not all “clean,” “natural,” or “dermatologist-tested” products are beneficial.
Fix it:
Look for:
Clinical studies
Medical-grade formulations
Ingredients with proven benefits (retinoids, vitamin C, niacinamide, SPF)
Dermatologists select products based on results, not hype.
