I have fielded this question from multiple people, and I know from my own sales data that many people are not using a toner, or not regularly. Perhaps more information is needed to convince you to include a toner in your daily regimen. When you're using the right one, you won't want to be without it.
In some product lines, toners are used to balance the pH of the skin or finish the cleansing process because many cleansers are alkaline or strip the lipid bi-layer (acid mantle). In Dermalogica, however, the cleansers are already acid balanced so a toner is not needed to restore the acidity of the skin. Dermalogica toners add additional moisture to the skin, but more importantly, help transport the next product (ideally a treatment serum) deeper into the epidermis. The deeper into the epidermis active ingredients travel, the more effective they are. So, think of a Dermalogica toner as a product booster; you'll get more bang for your buck out of your treatment serum. Toners can also be used to refresh and hydrate as needed throughout the day, even over makeup.
In the Dermalogica line, there are 5 toner formulas to choose from based on skin type or benefits desired.
Multi-Active Toner- An ultra-light spritz that refreshes and hydrates the skin while smoothing the surface. Helps condition skin to prepare for proper moisture absorption
Antioxidant Hydramist- A refreshing antioxidant shield with flash-firming properties to improve skin texture, fight damaging free radicals and intensely hydrate dry, dehydrated skin.
UltraCalming Mist- A soothing, hydrating mist that quickly relieves sensitivity while helping to calm redness, stinging and aggravated skin.
Redness Relief Essence- Lightweight like a toner but concentrated like a serum, the refreshing formula visibly reduces redness and helps reduce sensitivity by strengthening the skin's moisture barrier.
Breakout Clearing All-Over Toner- For teens, this toner contains several botanicals, including salicylic acid, that help reduce oil and bacteria to clear breakouts.
Application note: instead of spritzing directly on skin, you can spritz a cotton ball and wipe it over your skin.
I'd be happy to advise you on which formula is right for you!
