Mari where do you get all this information from? Cause id like to know about what about really i should be looking out for and what i should not when buying products, may be it will help with some of my confusion!! However though in the future though id love to be able to DIY some of my stuff will work out far cheaper too.
Thanks
Actually -- I learn a lot from watching the shopping channel and listening to what the product mfg. say about their products. If I can access the ingredients I look them up on skin care and find out what they do.
As far as nano technology -- this is very new to me -- I've read some very positve reports saying how it will change medical and cosmetic formulation -- for instance for medicine it could very well delivery a potent medical compoun to reach deep into a tumour and zap it. For cosmetics it could penetrate into a deep wrinkle and help puff it out. On the other hand I can't seem to get answers when the nano particles stop penetrating. They have now passed various agencies with approval in the UK and US, some question still in Canada.
So get the list of ingredients, check skin care and check out the product or ingredient. You can also do this on skin care dictionary -- but they don't have a lot of the new compounds.
Making your own serums makes sense because of the cost -- but you have to make sure you are buying the proper ingredients. I don't make my own -- chemistry was my poorest subject. I also check where a product is made.
