As much as I hate the implications of saying to cover up acne and everyone who used to tell me not to worry about I still got very good at covering up my spots. I do not have some crazy routine that involves layers of foundation or stuff like that. My skin shows redness really easily. Even a moderate pimple will leave a mark for a few days. I am doing this because I have found some products that are cheaper and do a decent job with cover up. My skin tone is uneven, red, and I still have marks as well as recent pimple ones. Some basic stuff can give me a more even face.
Foundations: I have been using BB cream- Maybelline (it is really light coverage) or SK79 (a Korean thicker coverage). I don't glob this on my face. A dot of cheeks chin and forehead goes a long way. Neither product has broken me out.
Covering red/pimples: I use a brush- small and thin bristles works best. I will dab some bb cream on the spot. Blend it with the brush. Next I used Exposed Organics concealer in green- really great to blend and counteracts red. I usually will put Dr. Murad salicylic acid concealer stick-this is in a lighter shade for me. I use these all with a brush and do variations of seeing the best coverage that blends and does not look like to much and matches my skin shade. I finish off with my powder foundation- light on the powder. I will use my brush with the powder to finish the spots.
Tips: it can be frustrating. Sometimes I have to start over. Best to work in the tiny layers to see how it goes. Sometimes depending on the pimple or mark a little bit of white eye liner can really take away red and makes a better base for skin matching foundation. With a whitehead that is pretty big using a really fine point brush and a dab of brown eye shadow on it can actually make it look nonexistent. However this is tricky. You don't want it to look brown and like a mole. Be aware that it stays on the whitehead part and not lower on the pimple. This trick takes practice. Visine dabbed on a spot can work with redness especially after popping a zit. The key is to have moisturized skin before. Dryness will show the coverage. If that happens for me I will use Vaseline of the area.
For anyone who struggles with red cheeks I will start using Clinique's foundation for redness. I will see if that is better coverage than BB creams. Again this for people like myself who do cover marks/ acne. It actually does not amount to much makeup. Makeup has never been a cause with my acne. Cover up is not a solution by any means to acne. Even celebrities have to cover up spots. I hope this helps anyone if they do chose to cover up.
