OK, no freaking out, that will only make it worse. I’m an esthetician, so here’s some advice and tips.
Yes, it is most likely the lack of birth control. This isn’t the right time to be experimenting or changing things that work. I have been off of birth control for almost as long as I have been an esthetician (about 5 years or so) and I still can’t 100% keep my skin in check. Some people are blessed with the ability to fight off the P.acnes bacteria that lives on our skin, some of us, we have to work a little harder 😉
First, are you washing your sports bra and clothing that you wear each time you work out? This is key! Second, while you work out, pat your forehead, don’t swipe away the sweat. Are you wearing makeup when you workout? Third, are you flexible? I ask because if you are able to reach your back blemishes, that’s not good, lol…don’t mess with them! Go get a few back facials, get some peels and some microdermabrasion. Go see your dermatologist and get a topical treatment that you can put on at night to help heal and kill bacteria.
7 weeks is enough time to clear this all up, but you have to start now. Look for a spa that has high frequency and cool beam/LED light treatments to help prevent and heal up the skin.
Please don’t go buying Pro-Active or any treatments for acne that you see at the drug store. You can try Dr. Dennis Gross’s Alpha Beta Body Peel pads, but be careful in the sun with any glycolic or salicylic usage. Actually, speaking of the sun, since you’re out in Las Vegas, you have some good sun out there, so, go lay out early in the morning, before 10 AM, before it gets too strong, lay out on your stomach for 30 or 40 minutes without sunscreen — I know I know, but it will have an antibacterial effect on your skin!
Start taking Vitamin C Ester, drink lots of water to clean out your body, eat lots of fruits and vegetables – you need your antioxidants and Vitamin A & D!
Start with this and let me know if you have any questions!
