Have you ever questioned whether your favorite product started losing its effectiveness after time? Or if it’s all in your head? We have, and dermatologist/dermasurgeon Dr. Michael Gold confirmed that we are, in fact, not going crazy and there are many different reasons for products to cause varying results.
Dr. Gold is here to clear up why your favorite product may not be working as well as it used to and how to avoid this problem:
Routine Change: If you have changed your regular application routine which has been working for a while, try being more diligent and sticking to a consistent schedule
Shelf Life: If you are using an old product, the active ingredient can lose its potency, reducing the effectiveness of the product. Toss out products shortly after the expiration date. It’s also a good idea to note the smell—if it’s starts to change chances are the actives have changed and it’s time to throw it away.Skin Tolerance: When you use a product for a long time, at times your skin can become tolerant to it and it stops working as well as it used to. For example, Dr. Gold says that medicated shampoos lose their effectiveness over time, which is similar to the reason that some OTC products are not as good as prescription products.
Expecting Too Much: Do not over-estimate what a product can do. Dr. Gold says we often expect more than what the product can actually do. Sometimes you believe you have just bought the next miracle cream, when in fact, it does little more than what you used to use.
So stick to the products that work best for you and when in doubt consult your dermatologist.
