I buy little dropper bottles, put a few drops of the 100% in them, fill the rest of the way with Witch Hazel water. You can also add it to a “carrier oil” such as Jojoba oil.
If you’re not using much, the Body Shop one is fine and really good. But with my sister, aunt and cousin all starting electrolysis, everyone needed a bottle to stop any whiteheads appearing after treatment.
It’s best used when you feel a spot coming up, or on active spots or whiteheads, just to combat the bacteria. So you only use a drop on a cotton wool pad and dab it on. It can be pretty irritating, which is why it’s best to use it sparingly.
Otherwise, witch hazel products are great for healing to lessen marks and stuff when the active spot dries up.
I use Witch Hazel a lot more as it’s beneficial to use everyday. Whereas TToil is just for when something comes up for a day or two, or directly after electrolysis.
