Natural skin toner removes surface skin cells, excess oils, and exfoliate dead skin cells. A right toner should soothe, nourish, calm blemishes, and delivers active ingredients to freshly cleansed skin. It should be mild, hydrate, and lightweight, allowing your skin to breathe and heal itself during the night. Toners can be packed for your travel in your bag as an economical way of face mist to fresh and mist your face throughout the day. Aloe vera and hydrosols make the best toner ingredients can be used individually, blend them together, and even include a few essential oils.
If you are to add essential oil in your own skin toner, remember essential oils are oil-soluble, and aloe vera and hydrosols are water-based. The essential oils will not stay dispersed through the base of your skin toner, and you will need a solubilizer to blend the oil into the water base. Without a solubilizer, any essential oil added to hydrosol, in this instance, will have oil droplets floating on the top of the water, as oil and water do not mix well. This can cause sensitization and unwanted reactions if essential oil used is exceeded the dermal limit. Using solubilizer will create the overall finished product to have a clear and transparent appearance. It is also covered in my Essential Oils for Organic Skincare to learn how to apply a solubilizer so you can create your own toner with essential oils.
