Hi @lenajam ! Most of today's toners are really just watery delivery vehicles for hydrating, antioxidant, or exfoliating ingredients. "Toner" and "essence" are interchangeable, as far as I'm concerned. Back in my day, toners used to be alcohol-heavy astringents designed to remove excess dirt/oil/makeup and lower skin's pH after use of highly alkaline cleansers. Since today's cleansers aren't so alkaline anymore, there's not much need for pH-adjusting tonersโand thank goodness, because those toners were super stripping and drying. Today's toners aren't like that, for the most part.
You might not need a toner, but here's what many of them do for your skin:
Hydrate your skin after washing - these toners contain ingredients like hyaluronic acid (often sodium hyaluronate), PCA/sodium PCA, carrageenan, trehalose, polyglutamic acid, birch sap, honey, peptides, various forms of sucrose, and other hydrating ingredients I'm forgetting right now. They're great for dehydrated skin. My favorite hydrating toner has been discontinued, unfortunately. But there are plenty of other options on the market. An "essence" can also be used for this purpose: I currently use and love Neogen Dermalogy Real Ferment Micro Essence each night. There's also a "toner" version of that product, if you're interested. COSRX Hydrium Watery Toner is another option: it contains 6 forms of hyaluronic acid. Or consider COSRX Full Fit Propolis Synergy Toner, which contains panthenol, propolis, and honey extract.
Exfoliate your skin - there are AHA and PHA toners that can remove dead skin cells from the top layer of your face, revealing newer skin. If you already use a leave-on chemical exfoliant product or a physical exfoliant (like a cleansing scrub or spin brush), then you don't need an exfoliating toner. In fact, that might be overkill for your face: it's easy to over-exfoliate, which leads to painfully damaged skin. If you choose an exfoliating toner, especially an AHA toner, use it just 1-3 times a week (never twice on the same day) to avoid over-exfoliation. A good gentle option is
The INKEY List Polyhydroxy Acid (PHA) Gentle Exfoliating Toner 3.4 oz/ 100 mL
. Some folks love
The Ordinary Glycolic Acid 7% Exfoliating Toner 8 oz/ 240 mL
. When I first started using chemical exfoliants, I used First Aid Beauty Facial Radiance Pads 28 Pads as an exfoliating toner.
Deliver antioxidants/active ingredients to your skin - this includes vitamin C toners, niacinamide toners, etc. I've used and enjoyed the Good Molecules Niacinamide Brightening Toner: it contains niacinamide and a stable vitamin C derivative (3-O-ethyl ascorbic acid).
Remove traces of makeup left after washing - not necessary if you already double-cleanse (oil cleanser/cleansing balm/micellar water, followed by a more traditional gel/cream/foaming cleanser). But, eh, itโs another reason to use a toner. Any of the exfoliating toners I mentioned can work for this purpose. Some folks use 100% witch hazel as a toner; if your skin's not sensitive to witch hazel, you could try that. (I used to do this but had to stop because it was wrecking my skin over time. Your results may vary.)
