No. No need for colour correctors, or concealers. Remember, foundations are red blockers to begin with. Just follow your dermatologist’s recommendation on how long you should begin your after-care skin care and make-up routine.
Make sure you use a dermatologist recommended foundation brand such as Kryolan’s Dermacolor line, Dermablend, Cinema Secrets, Cover F/X, and Joe Blasco. Yes these foundations will be creme based, as they will provide the best coverage with the least amount of product being used. Don’t forget to gently powder to set it.
A little segue, but not totally off topic...
(The issue with green colour correctors, is that you’ll need to match it with the exact shade of red to neutralize it. If the shade is not an exact match, you will look grey. And then you’ll have to use a concealer to cover that. It’s a big and long drawn out process to find an exact match. This corrector theory has been around since the 70’s and thanks to continuing technological improvements in the cosmetic industry, has not been practiced for decades. Hence all foundations on the market are red blockers. All one has to do is match their skin tone, and viola they’re done! But not all are recommended for laser resurfacing or cancer after care routines.) Hope I didn’t digress too much.
HtH good luck!
