Hi,
I sympathise. I have tried a whole range of skin care products, from expensive to cheap. I won't bore you with the details, but none of them really suit me.
I am now 49, have drier skin than I used to (was T-Zone combination, etc). However, my skin is in good nick, apart from the more evident open pores, and I get compliments on it (not being vanl, just wanting to demonstrate that independent evidence suggests my skin looks fairly good!!).
I am using a range called Dermaviduals. It may be just a beauty salon job, but there is no perfume, just conservative products. Creamy cleanser, taken off with a hot cloth. Then, just a moisturiser, which you can have custom made (ie, 'active' ingredients added by your therapist). There are eye gels and other stuff, and the most fabulous suncream. If you are buying Clarins you can afford this range. I like Clarins because it smells nice but it didn't do anything for me at all, and I end up disappointed.
My magic ingredient is a Clarisonic Mia (buy on-line, get as cheap as you can. You only need the most basic machine with one brush - don't get sucked into the idea you'll use it all over the body and therefore I'll buy the big version -unless you are a habitual body exfoliator). It has really made a difference, and no matter how crap my skin can look on a bad day, I know it would look worse without the Clarisonic. I noticed you have sensitive skin, so you'd need to treat it with caution, although it is gentle. However, it might not be for you. It is in effect a gentle exfoliator which is meant to do all other kinds of stuff that I can't be bothered to read about because I don't believe even half of the claims made for various products, tested on two and a half dogs, etc.) Reviews seem to be that people love it or hate it. You'd need to see for yourself.
The Dermaviduals would possibly suit you. The problem with Clarins, etc, is that they are essentially cosmetic products, not proper skincare products. I don't know where you live, but maybe (finances allowing) you could see a reputable beauty therapist and start using a different range?
And anyone else- please don't tell me off -if you are using Clarins or anything else and that suits you, then I'm not arguing with that at all. I am not slagging off every other product. I just never found anything I like as much as Dermaviduals. I was using the Environ range before that, but I like this better.
Good luck.
