Hmm....I can honestly say that I know very little about wrinkle reduction at this point. I am looking into it more, because I'm sort of to the point where getting too little sleep really starts to show up, and it's never too early to start really taking care of your skin, right?
I don't know about Thermage, but I do have a bit of rosacea, and so I know the pulse lasers (is that like light therapy?) can do WONDERS in reducing redness and evening out skin tone. I am planning on getting some of that done in the next year or so. You would need to consult with a dermatologist though, because there might be something over the counter that would work just as well or better. Have you seen a dermatologist? I would recommend making an appointment with yours or getting a recommendation from a friend or someone you think looks really great or has "had some work done" and consult with them about what they think you can do. There are TONS of options out there, over the counter or surgical or microdermabrasion or acid peels, etc.
Do you wear sunscreen now and moisturize everyday? If not, that is definitely a first step. You want to stop the damage now and then address what's already occurred. I use Neutrogena Healthy Defense Daily Moisturizer with SPF 45 in the morning under my makeup, and at night I use Neutrogena Anti-Oxidant Age Reverse Night Cream, which is good for someone who's just starting to show signs of aging/damage, I think. A friend of mine is 44 and she looks freaking AMAZING. She started using Neutrogena Healthy Skin Anti-Wrinkle Intense Serum around her eyes, and I could actually see a difference after a few days, I wasn't even looking for it. You might give this a try. But I would definitely consult with a dermatologist.
Hey, off topic, but will you post a picture of yourself in the cardigan? I will post one of me, too. I think it would be fun to see it on someone else, and we could swap outfit ideas. You're the one with the cardigan, right?
