DIY Won’t Fix Your Skin: Why Self-Diagnosing Is Hurting You

Let’s be honest--we live in a Google-it, figure-it-out, watch-a-TikTok-and-do-it-yourself world. And hey, that’s amazing when you’re learning how to hang a shelf or make sourdough. But when it comes to your skin? That fierce independence might be leading you down the wrong path.
At Tierny Tassler Skincare, we see this all the time: people spending hundreds—sometimes thousands—trying to fix their acne, dark spots, or anti-aging concerns with products they found from influencers or Reddit threads. And yet, their skin isn’t getting better. It’s often getting worse. 
Here’s why self-diagnosing your skin issues is almost always a bad idea:


1. Your Skin Isn’t a One-Issue Puzzle.
Acne isn’t always “just acne.” Dark spots aren’t always “just sun damage.” And that dry, flaky patch? It might be a dozen different things. Skin conditions often look alike, but they can have totally different root causes. That’s why slapping on random treatments rarely works—because the problem wasn’t what you thought it was.


2. TikTok Trends ≠ Paramedical Skin Care Training
We love a good skincare tip as much as anyone. But relying on influencers, forums, or friends to guide your routine is like asking your barista for dental advice. It’s well-meaning but potentially harmful. Without knowing your skin type, medical history, lifestyle, hormone levels, product history, or environmental factors, no one can give you the right evaluation and solution.


3. The Wrong Products Can Make Things Worse.
Self-diagnosing often leads to using harsh exfoliants, stripping cleansers, or going with trendy activities that your skin isn’t ready for. Over time, this can weaken your skin barrier, increase sensitivity, and even trigger new issues you didn’t have before.


4. You Could Be Missing the Bigger Picture.
Sometimes, skin issues are the surface symptoms of something deeper—hormonal imbalance, food sensitivity, chronic stress, or an underlying health issue. A trained eye can spot these connections. A random product from the beauty aisle? Not so much.


5. It Costs More Than You Think.
All those “maybe this will work” products add up. And when they don’t work, you move on to the next. And the next. By the time you get real help, you’ve spent a small fortune—without results.


6. Stressing Out Doesn’t Help Your Skin (But It Does Happen)
Not knowing what’s really going on with your skin is frustrating and stressful. And guess what? Stress makes most skin issues worse. If you’ve been spiraling through skin-anxiety loops and mirror panic, you’re not alone—but you do deserve better.

Just last month, I helped a new client—we’ll call her Patti, to keep things completely anonymous— who had gone through all 6 of these cycles. She is a brilliant business person, a great problem solver, and a busy mom. She was at her wits' end, because she’d run out of options and nothing was working. Thank goodness her mother-in-law recommended me to her. I uncovered her issues and acne triggers, and in less than 4 weeks, she’s well on the way to fully healed skin. Patti is no longer embarrassed to go out of the house!
