Project pan: Is an incentive to use up a certain product then rewarding yourself with something new and shiny.
I have done this myself with make up several times thanks to Back to Mac, I also have cheated by squeezing out product into another bottle to get there quicker. However we won't talk about that.
This week I did it for the very first time with not one but TWO skincare products. My skin has always been up temperamental and I have been on the hunt for the perfect routine since I can remember
Clean and Clear: Should not be flogging this stuff to teenagers with acne, highly fragranced and irritated my skin
Clinique 3 step: Paint stripper would most likely be milder
Cetaphil: Does nothing, ended up using it as hand soap
Ella Bache: Would be great for older skin, however too rich for mine.
Dermalogica: Works okay however never gave noticeable results.
Neutrogena: Like the wave, however its rubbish compared to my Clarisonic
Fast forward several years and I have found products that work for me.
I have been using Philosophy's 'Purity Made Simple' for 8 months now and it gently and easily removes make up. My skin is left clean and not too tight or dry. Works well with the Clarisonic as it doesn't foam, I would imagine a foaming cleanser would be quite messy.
Philosophy products are alot of fun. The shower gels/ bubble baths come in fun scents. I have 'Vanilla Birthday Cake' and 'Melon Daiquiri' . I would of purchased 'Beach Girls' at Sephora if it wasn't so heavy.
The 'Micro Delivery Peel' is a two step process that gives a salon worthy exfoliation.
'The Supernatural' gives a great light coverage that is perfect for summer. The sponge applicator on the top is a pain in the arse though.
Kiehls Ultra facial moisturiser is another favourite of mine. The thing I love about Kiehls is their policy around samples. They don't advertise, they sample to get the word out. I love when making a purchase they ask what samples you would like. I received a sample of the Ultra Facial Moisturiser when picking up a bottle of Creme De Cops body lotion.
The Ultra Facial moisturiser is light and very low in fragrance, it absorbs quickly into the skin and love the tinted version also.
Even my dogs use Kiehls products.

my empty bottles, Photographic evidence that I actually did it.
