How can I tell if my new product is working?

It’s surprisingly difficult to tell sometimes, isn’t it?


First, you have to give a new product 60-90 days, unless it irritates you.   Change only one product at a time.  Make sure the difference you’re seeing isn’t just seasonal or a fluke … in you just got back from Hawaii and your skin looks worse/better, etc.  


It helps – okay maybe this is a little too scientific – to keep a small notebook and just write the product, start and end date, and your impressions after 60-90 days.   One good measure is are you getting more compliments on your skin?  

“Selfies” aren’t that helpful because the lightening and angles vary too much to get a good photo.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
