Love,Love, LOVE This Cleanser – Dry Skin Game-Changer!
I can’t say enough good things about this cleanser. I have very dry, sensitive skin, and it’s hard to find products that cleanse effectively without stripping my skin or leaving it tight and flaky. This one is a total winner! The texture is creamy and gentle almost soothing when applied. After using it, my skin feels clean but still soft and hydrated. No irritation, no tightness, just a beautiful, healthy glow that I haven’t seen from a cleanser in ages. I’ve actually started looking forward to my skincare routine again because of how good my skin feels afterward. Another huge plus? No breakouts. Sometimes rich or hydrating products can clog my pores, but this cleanser hasn’t caused a single issue. In fact, my skin looks clearer and more balanced since I started using it. I’ve been pairing it with the Thayers Milky Toner, and the combo is a dream. The toner adds another layer of hydration, and together they leave my skin feeling plump, dewy, and calm. I’ve had multiple people comment on how radiant my skin looks lately, and I give all the credit to this duo. If you have dry or sensitive skin and want something gentle but effective, I highly recommend trying this. It’s officially a staple in my routine now!

Absolutely Fabulous for Any Age - Not To Be Missed
Whether you have a 15-step skincare regime or are extremely low maintenance in your skincare routine, this is a product that is an essential component to a healthy, radiant complexion. I’ll admit, my skincare game became fairly extensive as I approached 40. Prior to that, I had a solid day and night routine using 4-5 products.
After 40, my skin required more effort with a focus on hydration, prevention of damage from sun, stress, lack of sleep, etc., barrier building, and aging gracefully. At 55, people often comment on how nice my skin is and some people think I’m still in my 40s.
I owe that to a fantastic arsenal of skincare products rather than procedures (plus water, solid nutrition, and at least 8 hours of sleep per night). Nothing wrong with getting Botox or fillers, but I’m rather frugal and would rather focus on daily maintenance to ensure my skin looks as good as possible regardless of my age.
This milky toner is as good - and actually better - than brands at much higher price points. It’s thick (in a good way), provides instant hydration, and keeps my skin glowing for hours. I use it in the morning as part of my AM skincare routine, as part of my skin prep prior to doing my makeup, and every night in my PM routine.
Some people use milky toner as a setting spray (mix equal parts toner and distilled water into a spray bottle and lightly mist your face once your makeup is complete). I prefer a setting spray that provides staying power rather than additional hydration, but I have sprayed this mixture on my face if I feel dry and my skin looks parched. It feels really nice on a hot day, especially if you keep the mister cool in the fridge.
I have tried adding drops to my foundation, which is a “viral” trend, but I find this product to be a bit too thick. A thinner consistency like the Byoma Milky Toner works better for me if I want to create a more dewy foundation. I find that using this Thayers product as part of my skin prep prior to foundation along with using a dewy, hydrating foundation is better for me.
I love that this bottle is huge, affordable, easily obtained from Amazon, and incredibly effective. It’s earned its spot in my holy grail products for life.

Gentle Milky Cleanser That Mostly Delivers on Hydration
I picked up the Thayers Milky Hydrating Face Cleanser with Snow Mushroom while it was on sale because I was looking for a non-drying face wash.
Overall, I do like it. The texture is gentle and milky—it doesn’t foam up, feels non-irritating on my skin, and rinses off easily. I also paired it with the moisturizer from the same line (though I skipped the toner since I already use one my skin prefers).
It does a good job cleansing without stripping my skin too harshly, which I appreciate since I tend to lean dry. That said, I do notice a slight dryness after washing and drying my face, which surprised me a bit given the “hydrating” claim.
One other small downside is that the packaging was a bit difficult to open.
Still, overall it’s a gentle, easy-to-use cleanser that feels calming on the skin and doesn’t cause irritation.

Leaves face feeling clean, soft, and smooth
Love this facial cleaner. I actually double cleanse my face. First I use an oil based makeup remover, then I cleanse with this face wash. It doesn’t strip my skin of moisture, and I’ve noticed less redness on my face after switching to this cleanser. The cleanser is light and leaves my face feeling clean, soft, and smooth. I would recommend to people who notice their face feeling “tight” or noticing redness after cleansing.
