There are no creams on the market that reduce muscular contraction. If there were, you wouldn't be asking that question on this website. You would know the answer and the whole world would to. It's very hard to keep something like that secret.
But, all patients over the age of 30 should be on Tretinoin which is the topical form of Vitamin A. All ther other alternatives to Tretinoin (Retinaldehyde, etc) are cousins that are far less potent and don't get the job done. I find that patients who say they can't tolerate Tretinoin (Retin A) haven't been properly told how to use it. My office also compounds a type of Tretinoin that has other ingredients to make it more tolerable and enables the patient to use a higher percentage Tretinoin (Retin A). Even 90% of the rosacea and sensitive skin patients can use it.
Otherwise, sunscreen is the other biggy. If you're going to use tretinoin you have to use suncreen or you'll get more photodamage. Good suncreens are ones that contain zinc oxide and titanium dioxide because they are physical blockers and don't allow any rays to get through. I like Eucerin Facial for sensitive skin SPF 30. Skinceuticals and Obagi make great sunscreens to which are really light and fragrance-free.
