As I've mentioned before, my skin isn't outrageously acne prone, but when I do get a breakout it'll leave its mark on me for months. Right now for example, I don't have any active spots (knock on wood that I haven't just jinxed myself), but I still need to put on some kind of concealer or foundation to hide all the marks making it look like my chin and area around my nose are covered in spots. I've found some products that have really been helping to clear up the scars/dark marks left over faster than ever.
I've found that using an exfoliating toner has helped leaps and bounds. When I have an active breakout, I like to (gently) scrub at it with the toner - it not only to helps heal it faster, but I'll get a less prominent mark that will fade more quickly than if I hadn't used the toner. My favorites have been the Pixi Glow Tonic, paired with some exfoliating cotton pads (seriously life-changing), and the First Aid Beauty Facial Radiance Pads. I like using the Pixi Glow Tonic every night and the Facial Radiance Pads every other morning/2-3 mornings per week. Since both are very gentle exfoliators, using them this often and together doesn't irritate my skin or cause me to over-exfoliate. My skin has never been brighter and smoother.
A spot will scar the worst on me if it's been popped. I never purposely pop my pimples because of this, but sometimes it just happens. I always make sure I've got the Origins Super Spot Remover on hand to put on the spot right away to clear it out. It stings for a second if the spot is open, but it goes away quickly and helps the spot not leave a huge scar on my face - some quick stinging is definitely a fair trade for that.
At night I've been using the Indeed Labs Peptabright Serum before moisturizing. I've been using it consistently for about two months now, and it really has made a difference. It faded the acne scars I had over time, and now new scars don't last as long. It also really helped clear up the patchy redness I was prone to around my nose and on my chin. It feels really moisturizing as well, so I'm not trading the appearance of my skin for its nourishment.
Another essential that I've found really helps is using rosehip oil (I got a giant bottle from Eve Hansen Beauty on Amazon here). It's been lovely since my skin has been dry and dehydrated from the cold. It sinks in quickly and leaves my skin feeling velvety soft rather than greasy, so I reckon it would be helpful for people with more oily skin than me as well. I didn't see results right away from using this, but after using it consistently for two or three months I can really see the benefits. It did help clear up acne scars, and it also helps clear up active breakouts! It felt really weird to put oil on a pimple but it does help clear them up. I think this will be a staple in my evening skincare routine for a long time.
One last important thing to help acne marks and scars is to wear a facial SPF. I don't every day because I work in an office with literally no daylight, but if I know I'm going to be out in the sun I'll put one on. I like using the Neutrogena Healthy Defense moisturizer with SPF 50.
And as I'm waiting for these products to really clear up all of my marks, I've been loving the Nars Radiant Creamy Concealer to cover everything up!
