Question: I feel like I try a new serum or moisturizer and get great early results but when I remain faithful, overtime I feel nothing more changes. Is it me? Should I rotate products to get better results?
Answer: This is one of my favorite topics! We ( consumers) have all experienced this. We fall in love with a new skin care product only to see the once wonderful benefits seem to twindle away. Doctors and other skin experts have a boatload of different reasons as to the cause:
1. When we first use a product it provides fresh new benefits, as it supplies what the skin needs. Over time, other problems and isssues develop and the once new serum or lotion cannot meet the new needs.
2. Some dermatologists believe that the products still continue to work , but we’ve forgotten how bad our skin looked before. In other words the original improvements are still there, but now we want more.
3. Then there is the phenomenon of “New User Benefits’. For example, if you’ve never used an exfoliating scrub, the first time results are remarkable. You have just taken off layers of dead dry skin and your skin just glows. Regular exfoliation will continue to clarify your skin but the shock and awe of the first time will not be repeated.
4. If you’ve purchased a second bottle of a favorite product only to be disappointed at the results, its possible that there’s been a “Change in Formula”. One or more of the key ingredients had become too expensive, was in short supply or even deemed unsafe. Different ingredients, different results.
All of these are pretty subjective reasons for a products decline, but in at least one case clinical studies have shown that skin cells do become resistant to an ingredient. Researchers have found that after about six months skin cells no longer respond as enthusiastically to alpha hydroxy acids like glycolic acid. The benefits continue, but not as dramatically as when they were first introduced to the skin.
To bottom line it, there are numerous reasons that products seem to become less effective over time. The question is what to do about it. People report that rotating products seem to slow the loss of power, but jumping around too frequently will not allow the skin to get full benefits from a forumla. Try using each product for two- three weeks at a time to allow the skin cells go through a full growth cycle before switching to another option.
Have you found that skin or hair care product seem to deliver less and and less benefits? How did you handle it?
