To get good skin, everyone knows that water, avoiding soda, and taking your vitamins are a must. The real reason why I have great skin? Because I'm a major proponent of preemptive care!
My whole life, I've had people tell me I have great skin and that I [said with a hint of annoyance] "never get" acne. My first secret is that when I got my first blemish in sixth grade, I rushed straight to the dermatologist for treatment. This was probably one of the first warning flags that my mom saw, telling her she was raising a perfectionist (I prefer "strong attention to detail"). Since then, I've tried relatively mild topical and oral solutions, but post-college, I didn't want to be committed to putting unnatural things into my body.
For day-in, day-out use, I swear by:
Neutrogena's Complete Acne Therapy System (Three step skin care process). Be careful with colored towels and sheets, because it will bleach them. I always use white sheets and towels for this reason (the night cream has a little bit of Benzoyl Peroxide in it).
Here's my skin sans makeup - On a safari in Africa, nonetheless! Definitely no concealer.
However, I usually swap out the Neutrogena daily moisturizer for Shiseido's The Skincare Day Moisture Protection SPF 15, because I find it less greasy.
I also alternate face washes with good ole St. Ives. I love St. Ives Apricot Scrub, as well as their Green Tea Scrub. I usually use my Clarisonic Mia face brush in the morning with a St. Ives face wash, and save Neutrogena for the evening.
For on the spot treatment, I recommend Clean & Clear's Clear Advantage Acne Spot Treatment.
For a gentler treatment system (no Benzoyl Peroxide), I also love La Roche Posay's skin treatment system: Effaclar Purifying Foam Gel and Effaclar K Duo Dual Action Acne Treatment.
More on vitamins and nighttime skin regime later. This covers your basic foundation for good skin. Your best face forward is always a clear face! You should be confident enough in your skin to not need to wear foundation to the gym.
