The Essential Guide to Natural Skin Care by Helene Berton

Treat yourself--your face, hands, hair, and lips--to vitamin-rich, toxin-free nourishment from nature. The Essential Guide to Natural Skin Care maps the wondrous qualities and uses of botanicals used in homemade beauty products, making it easy to customize your own lotions, creams, milks, body butters, face masks, lip balms, ointments, toners, and more.

Choose from a wide variety of eco-friendly vegetable oils and butters, infused and essential oils, aromatic hydrosols, and emulsifiers. Discover the beneficial beauty and healing properties of each, as well as their practical traits, such as shelf life and absorption. 

You'll find ingredients that soften, tone, and hydrate skin and hair; tighten pores; fade scars; stave off wrinkles; prevent and heal acne; promote hair growth; treat dandruff; fight infection and fungus; and repel insects. 

This portable, compact DIY reference also includes practical advice and basic recipes that can be easily modified to your unique skin type, needs, and tastes.

I bought this book as a substitute to DIY Pure Plant Skincare... at first glance, it's not as well set out, there are ingredients that can be difficult to source within NZ, however, there are some comprehensive tables at the back that can be useful, along with the basic percentages required to modify the formulas to create your own.  For it's cost, it's a good introduction to formulating.
