Is it better to buy a moisturizer in a jar or a closed pump system?

Moisturizers in a jar don’t really deteriorate the same way that antioxidants do when exposed to air.  It’s fine to buy a moisturizer in a jar and use it up within 3-6 months.  After more than six months or so, the oils in any cream or lotion may start to deteriorate.

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?!
