Not sure if she's coming back, but will post for anyone else interested.
Back in my 20's I would get occasional pimples on my chin and jawline, so I used pro activ, and it DOES work, but all that constant exfoliating is not good for your skin in the long run. Plus, I found it difficult going cold turkey because my acne came back with a vengeance, so I had to gradually cut down to every other day, every week and then nothing, which worked better. If you're desperate you could try the pro activ to get rid of your existing acne and then find another way to maintain it.
It's a combination of things... hormones, diet, lack of hydration and not cleaning your face well.
I'm a fan of healing the body naturally through your diet. Things like raw kale are great for skin and you can throw some in a blender and mix with different fruits. There are mixed opinions on eating raw veggies, especially Kale, but I believe in moderation is fine. Also, plenty of water as nothing really beats hydrating internally. I've found that drinking water just before bed always helps a lot.. I always wake up feeling refreshed and a lot of it is because the water is being used as the body is repairing itself while you sleep, and then you flush out the toxins as soon as you wake up. Try to eat organic foods too.
As for external remedies...
Raw unfiltered honey - very soothing and a great treatment for acne and also it's great for anti aging. Make sure it's raw and unfiltered, not "organic honey" because there is a difference. Best to apply to a damp face as it's so much easier to rinse off after. Really soothing and makes your skin feel really soft. There's an Australian brand called Manuka and it's very powerful. I've not used that one yet, but it seems to be the most popular for skin and general health, especially getting rid of flu etc.
Aloe vera gel - straight from the plant, not the tube! You can't either buy the plant, or some grocery stores will sell the leaves. There are lots of youtube videos on how to extract the gel. Usually it's best to apply to a clean face before bed and leave it on overnight, and wash off the next morning. Would not recommend eating it though!!
Sheet Masks - my favorites are Dr Jart+. I use the "Soothing Hydra Solution" as well as the "Porecting Solution - Bubbling Charcoal". Love them!! There is usually serum left over in the packaging so I apply to my hands, arms and upper chest area rather than wasting it. Best to do these at night before bed. After removing the mask, press the excess serum into your skin and then seal it with a night cream/moisturizer. Don't exceed the time for the mask because you don't want it to dry up. There are other sheet masks but these are the two I've tried and love.

Professional Treatments:
Chemical peels & non ablative Lasers - good for acne treatment and also getting rid of any acne scars. The peels are a nuisance though because you shed like a snake, and you can't touch your face, you just have to wait for it all to shed naturally. The laser genesis is what I think they use on teens as it's a mild laser.
Hydrafacial - they literally give your face a thorough clean, extracting debris from your pores.

Double Cleansing - would recommend this for giving your face a really good clean. Usually ideal is to start with an oil cleanser followed by a water or foam based cleanser. I know the oil cleanser might seem counter productive, but it's the best way I've found to remove makeup and after rinsing it does not leave you greasy. The 2nd cleanse then removes anything you missed the first time. If you're reluctant to try the oil then use a water based cleanser first, but in my opinion the oil works better.
Julep Konjac Cleansing Sponge - really love this. I use it on my face in the shower. A really gentle way to exfoliate. Skin always feels polished afterwards.
