It is actually medical make-up. A few years ago, make-up was not recommended by dermatologists. Today we understand that it improves our patients' quality of life. The existing products, which are fragrance-free, preservative-free and non-comedogenic, present no risk of irritation or sensitisation. I recommend medical make-up to my patients.
Then you use a corrective foundation whose colour most closely matches your skin. It should be applied in small quantities and gently spread over the face. To neutralise red tones, you can use a very small amount of concealer before applying the foundation. For redness, you can use green, a complementary colour, as well as yellow for more heavily pigmented skin.
I reassure patients by explaining to them there is no risk of aggravation. I have them test the textures of the products. I suggest a demonstration on a red patch. Patients are always surprised by the result! Then I teach them the basic techniques of medical make-up which are quick and simple.
