Thats a worthy idea, to add anti-aging ingredients! Trouble is, many of them are water soluble and tricky to put into anhydrous products. Secondly, scrubs are typically rinse-off products.
I manufacture a dermabrasion product and wanted to let you know there is a free webinar November 11, entitled Exfoliation Amplified. Visit "Skin Inc. Magazine" for further information. skininc@allured.com.
Hope this helps
