We prefer to use the Vitamin A Corrective as a spot treatment for PIH and Vitamin A with EGF is a full face treatment for anti-aging.  IT is more about the other ingredients in the products that guides us as to what to use them for vs.the Vitamin A itself.  THE EGF (Epithelial Growth Factor) is ideal for new tissue growth and what it works best as an anti aging product.  That being said, you can use the Vitamin A Corrective on the full face, and it does have peptides in it too, but if you are going for anti-aging you will get better results with the EGF serum.
