Paula's Choice store is having 15% off all their products and free shipping if you spend over $100. If you don't know what these products refer to you can check out this page(blog.skincare-addiction.com) for some extra information. Personally I just bought the 2% BHA + 8% AHA gel products plus the Benzoyl Peroxide treatment.
These products comes highly recommended for those with Acne problems but results are obviously dependent on your own skin type.
Paula's Choice products are highly regarded on the SkincareAddiction subreddit, which in itself is a great resource to educate yourself and find new products. If nothing else check the link out, helped me learn heaps about skincare.
Don't forget about the 3 FREE Samples on orders over $5.
Paula's Choice has also recently introduced a referral bonus of $15 off your first order when you spend a minimum of $30 (full disclosure, the referrer will also receive a $15 credit). If you would like to use my referral link to take advantage of this deal please find it here
I missed out last time they have spend $100 get $30 off, I'm hoping they'll have that one again soon :) 30% off is worth it!
