I'm interested in this topic. I've done a bit of superficial research on anti-wrinkle creams and have tried various types of product (e.g. Vitamin C products, Ibendone, Retin A, Kinerase, etc.) from different lines. I also know a little about aromatherapy.
Anyway, I write in American English, and can get your articles done in 4 days for $35. I'm new at freelancing, so I don't have a body of work to which I can refer you. However, I can assure you that I do a good job for you.
