Did you know that concealers come in different colors? ( I just found out) and they are based on the specific color of blemish you are trying to hide depending on your skin tone though....Concealers are best after foundation to avoid dispersing the concealer from the spot you intend to cover.

Using the color wheel might be a bit confusing but the use of concealer has an art to it and this explains it to an extent.

Green Concealers
These are meant for red blemishes (like the redness caused by breakouts) or just some red spot you have to hide (maybe from sunburn or some reaction). This will give a good base for the foundation you want to use.

I have seen one on jumia, green concealer.......so I think they are available in Nigeria. Skin redness is common. Anyone else know where to get?
