I know the Clarisonic's been revered as making a huge difference in people's skin, but I think what you put on your face is much more important than what you wash it with. If anything, using the Clarisonic too much might be harmful to what sounds like sensitive skin. I would use it every other day if I were you. As for skin care regimen, here's what I would do.
Morning:
1.Gentle cleanser, foaming or no, up to you, though foaming tends to be better for oilier skin types (I like Clean & Clear foaming sensitive, but phisoderm sensitive cream cleanser might be a better choice for you)
2. Chemical exfoliant with 1 to 2% beta hydroxy acid (salicylic acid). (Neutrogena oil free acne stress control 3-in-1 is the cheapest one out there) This is SO IMPORTANT. It brings forward healthy skin cells and cleans down into your pores. Though spot treatment may help in treating individual blemishes that have already flared up, it doesn't prevent new ones from forming. This does. And it's the only treatment against blackheads. It also reduces inflamation which will reduce redness. Seriously this will probably be the most important step for you. It may even help in reducing acne scarring, but that depends on its severity.
3. Wait 15 minutes
4. Optional: Moisturizer. If you find that the next step isn't enough after about 2 weeks of use, I would add a nice water-based moisturizer here. Suprisingly, Mac strobe cream is a decent choice and it has antioxidants which will help in repairing your damaged skin. Plus it's MAC and we're on Specktra
5. SUNSCREEN. Preferably, a photostable UVA/UVB sunscreen. That means a sunscreen with Zinc Oxide, titanium dioxide (or a combination of both), or Avobenzone (also known as parsol 1789) WITH octocrylene. I use cetaphil spf 15 and I really like it. If you are using a chemical sunblock (avo+octo, which cetaphil is) wait a little while before putting makeup up on.
Night:
1. Makeup remover. I like makeup removing cloths, most of them are good. You might want to avoid fragrances though.
2. Cleanser, same as morning.
3. Exfoliant, same as morning, though if you find you are reacting to it you may want to use it only in the morning (or every other morning) until your skin adjusts.
4. Wait 15 minutes.
5. Treatment. The best one at a non-exorbitant price in my opinion is neutrogena healthy skin anti-wrinkle cream night. It has antioxidants plus a synthetic form of retinol which will repair sun damage and acne scarring.
6. If necessary, a nice water-based moisturizer. Simple is best, and try to avoid fragrance and brands that claim to have fruits and flower extracts, which sound natural and healthy but will really most likely contribute to the redness in your skin.
I didn't include toners simply because I think they are necessary only for the most oily skin, and if they contain skin repairing ingredients or antioxidants, which are present in other products in your regimen anyway. They do remove traces of oil and makeup, but aren't needed if you're using a good cleanser and makeup remover.
So...this turned into a book. I guess I get a little carried away when it comes to skin care. Let me know if you have any questions or if you need product recs.
tl;dr: BHA exfoliant and SUNSCREEN!!!
