I definitely don't think it should be used as an aftershave. They can cause irritation if your skin is sensitive.
I took this from some website, hope it helps.
What Is A Toner?
Some of you may have read that last sentence and responded with “Toner. What the hell is toner?” Well gentlemen, a toner could be the missing link that you’re skincare regime has been crying out for. Of all the products out there (and there does seem to be an increasing number of serums, masks, creams, lotions and potions nowadays) a toner is often the product guys neglect from their routine. I think one of the main reasons for this is that many guys don’t understand what a toner could be doing for their complexion.
Masquerading as a light (often clear) lotion, toners can also come in the form of a spritz, or on toning ‘pads’. In whatever form, a toner is designed to aid your skin in one or a handful of the following ways:
Remove the excess oil that causes ‘shine’.
Prevent pores from becoming clogged with dirt and grime (causing blackheads).
Help to eliminate or control breakouts.
Refresh your complexion.
Refine skin tone and reduce pore size.
Sooth after shaving and prevent irritation.
When Should I Use A Toner?
A toner is primarily designed for use as part of a three step Cleanse, Tone & Moisturize routine. Once you've cleansed your skin with your chosen face wash, pat the skin dry with a towel and apply your toner (depending on the type of toner you use this may require a cotton ball or pad). Once your toner has dried, apply your moisturizer or mattifying product to complete your regime.
But that’s not all a toner can be used for. If you experience excess shine or grease throughout the day, then a toner can be used to control and eliminate this often embarrassing problem, and help prevent breakouts. Likewise, a refreshing toning spritz can breath new life into lackluster skin that’s under constant attack from dryness or external aggressors. For these type of grooming dilemmas the spray or toner pads are fantastic for an on the go touch up (see some of my recommendations below).
The final string to the toner bow is it’s post shaving benefits – helping to calm irritation, reduce redness and close pores after your razor has done its best work. Now do you see why using a toner might benefit your complexion?
Should I Be Using A Toner?
After all that, this is the big question isn't it? In short, the answer is probably yes. But I don’t just say that on a whim, here are some of the reasons you need to add a toner to your routine – whatever your skin type*.
