Best Product for Red Marks/Scarring

I have skin that marks very easily. Even one spot can leave a lasting mark. I have tried a lot of products to reduce the red marks and only one did I find that truly works. It’s the Image Iluma Intense Brightening Serum. This serum is hydrating but oil free and it is brilliant for reducing red marks in the skin. It’s about €50 which is good value in my opinion as it lasts about 6 months and it really works with consistent use.
