They Changed the Formula… Is It Still Worth Your Money? | Dr. Shereene Idriss

One of the most frustrating things in skincare is finding a product you love — and then realizing the formula has changed. In this video, I’m breaking down skincare reformulations: why brands change formulas, what those changes can actually mean for performance, and how to decide whether your favorite product is still worth buying. We’ll talk about ingredient changes, preservatives, texture, stability, active ingredients, packaging, price increases, and why a reformulated product is not automatically better or worse just because the ingredient list looks different. I also explain how I evaluate a new formula as a dermatologist: what changed, why it may have changed, whether the key active ingredients are still there, whether the new vehicle makes sense, and whether the product still does the job you originally bought it to do. Sometimes reformulations happen because of new regulations, supply issues, ingredient stability, safety, or an attempt to improve texture and tolerability. Other times, the new version simply may not work as well for your skin. If your favorite moisturizer, sunscreen, serum, cleanser, retinoid, or treatment has suddenly changed and you’re wondering whether you should keep buying it, this video will help you think through the decision without getting lost in ingredient-list panic. Because the real question is not: “Did they change the formula?” It’s: “Does the new formula still solve the problem I need it to solve?” Subscribe for thoughtful, ho
