I've tried a lot of products from SKII, La Mer and Khiels, here's my verdict :
SKII : not fond of their cleanser, essence miracle water and eye gel, but their facial treatment mask (sheet masks)which is great for hydration, I would say that this is the best hydration masks. It comes in 6 pcs of sheets in a box.
La Mer : It's a no, no for me, the creme too heavy (causing pimples), the gel is good but it has mineral oil, so in the long run will give milia to my already milia prone skin. The cleanser and toner just a total rip off, very expensive and very average, this is something cetaphil and other cheaper brand can also do.
Khiels : I'm trying out their products now, the Yerba Mate tea cleanser, just average, it's foam cleanser, can be a bit drying, may be suitable for younger skin the 20 something but not for 40 something skin. I just got a couple of samples for the Acai Damage Correcting Moisturizer, I love the smell, so far so good (only 3 days ago) and also the serum, the Powerful Strength Line reducing concentrate that has 10.5% pure vitamin C, not using this for lines but more for getting rid of the pimple scars. I will have to wait and see the result in a few more days, if it's okay I'm thinking of getting the serum from the Acai (Ah-sigh-ee) berry products as well.
