A couple of years ago I invested in two La Prairie creams. I didn't get much change out of £300. I was feeling crap as my then boyfriend was not being very nice to me at the time and I wanted a boost.
I bought the creams not particularly for their use but the look of them on my dressing table so that psychologically every time I saw them I felt that I was 'worth' luxurious products.
Both creams were were very rich but did absolutely nothing, they felt heavy on and the night one irritated my skin.
Suffice to say I have in thirty five years or more of buying face creams, I have bought cheap creams to the most expensive and the price tag is insignificant.
It's what works for you and in my experience at nearly fifty years old, I have not found that the price reflects on what the product can do.
I recently discovered petroleum jelly is far superior than any nail oil or cream and we all know how cheap vaseline is.
If you want to avoid Botox or other cosmetic procedures the only way to significantly reduce wrinkles is to wear a sunblock, sunglasses and a sun hat. Sunblock should also be worn in winter.
Genetics play their part as well and some will age better than others no matter what you slap on your face.
Find a skin cream that you like the look of, fits your budget, smells nice or is I scented if you don't like fragrance and it feels and looks like it is moisturising your skin without causing any breakouts.
