I like Paula's Choice, also, though current budget needs have pushed me into using less expensive BHAs. The good news is that my recent budgeting has paid off and I've paid off my small debts plus will be able to live slightly more luxuriously in a month or so. Woot!!! But I'm still a hippie who takes public transport, wears thrift store clothes, and is pretty happy most of the time.
I use Retin-A almost every day, and buy it from international pharmacies so the cost is about $8 per small tube, which will last 3 months. I put it on my face, the backs of my hands, and my shoulders which are (or were) freckled. I also buy a latisse dupe from the same place, for keeping my lashes and eyebrows thick. And a BHA ointment which is basically vaseline with 6% bha; this removes flakes, clears pores and also is very emollient. I don't know the pH (important for BHAs) or if the percentage is accurate, but it is very cheap ($6 a tube) and works well.
I use Stridex red jar BHA pads, which are 2% bha (the same as Paula's stronger BHA products) every day or so on my oilier places, and to get rid of the flakes from retin-A.
Sunscreen is my number one skincare purchase; I currently have a Korean product I love (Biore Aqua something) which feels like nothing on the skin, and also like certain drugstore sunscreens such as L'oreal and Neutrogena.
I also use insect repellant around my ankles nearly every day ... found a 'natural' one from Skin Essential Actives which smells lovely so that's the current choice. I'm super sensitive to mosquitos and fleas and they're nearly everywhere.
For cleansing I'm lazy and don't have special products; I use Bioderma sometimes, or other cleansing toners, for their ease, and also just wash my face with whatever soap I have in the shower. I bought a Japanese exfoliating cloth, Salux, and use this all over my body and face gently. I also rarely use moisturizers or body oils except for the BHA ointment mentioned above. Because I'm lazy and I hate owning a ton of products; whenever I buy them I end up tossing them a year or 2 later, nearly unused. I live in an area with relatively high humidity and my skin isn't dry.
The last year I started using Timeless' Vitamin C serum nearly every day; cannot honestly say it is making a ton of difference but perhaps it is? I also bought a hyaluranic acid serum from Timeless and put it on my eye area once every few days; again cannot see much difference. IMHO this ingredient is over-hyped. Also I'm experimenting with niacinamide in a small spray bottle, misted on a time or 2 a day. I bought this in powder form from Skin Essential Actives.
I also wear sunglasses and a hat with large brim when I'm out in the sun and also gardening gloves when I garden and these are so much easier than putting on, then washing off, creams for me.
