For me, it's SK-II. I buy it when I feel like giving my skin some extra pampering.
La Mer and La Prairie for me! I try to use these only sparingly though so I don't over-pamper my skin. LOL is that even a good idea?
Sisley for me ....
Ever read about SKII, Cannot guarantee yet whether the secret called "Piatra" (I don't know I spell it correct or not) can be a cause of cancer.
I'm a big fan of SKII before and switch the whole range to use Sisley.
i buy my La Prairie luxe body cream caviar from nieman marcus for around $325. i loove it!
I suffered a mild acne condition for over 12 years and I finally found skin care product that works for me. This is the only beauty product I'm willing to splurge my hard earned money. The skin care set cost about $620 CAD, it includes cleanser, toner, serum, eye cream, clarite (dark spot whitening cream), expoliate, active (night blending cream), sunscreen, and finally moisturizer. The set lasts about 4-5 months. It's called Skin Tx and I need prescription to purchase from my dermatologist.
Sorry for the long post.
