My Favorite Product in the Milky Line
Style: Milky Toner, Style: Milky Toner
This toner has easily become my favorite product from Thayers brand and all other brands. I’m very picky about my skincare routine, especially when it comes to products I use daily, and this one has completely earned a permanent spot in my routine. It feels incredibly gentle, hydrating, and soothing on the skin without feeling sticky or heavy. I love the ingredients, especially the snow mushroom and hyaluronic acid, because my skin always feels soft, balanced, and refreshed after using it. I’ve also noticed my pores looking smoother and overall healthier since incorporating this toner consistently. The formula works beautifully with the rest of the Milky line, and my skin genuinely looks and feels better when I use it regularly. I’ll absolutely continue repurchasing this product.

Hydration + glow without irritation!
Style: Milky Toner
I’ve been using this milky toner for a couple months now and it has quickly become a staple in my routine. The texture is lightweight but creamy, which makes it feel more nourishing than a typical watery toner. It absorbs really well into my skin without leaving and sticky or greasy residue. I haven’t noticed that my skin feels softer and more hydrated after applying it AND it layers so nicely with serums and moisturizers. One thing I really appreciate is how gentle it is on my skin. It doesn’t cause any irritation, redness or breakouts! I actually feel like it helps calm my skin on days when It feels a little dry or “stressed”. Overall, I think it is a great option if you are looking for a hydrating, soothing toner that fits easily into either a simple or more detailed skincare routine. I will 100% be repurchasing when I run out of my current bottle

This will make your face soft and glowy!
Style: Milky Toner
This is GOOD STUFF! First cleanse face, then I tried using both a cotton ball and a cotton round, but in the end, I put a small amount right on my fingers and massage into my face. It seems pretty wet at first, so I let it air dry for a minute before adding my moisturizer. My face really seems smooth and even has a glow to it, which is unbelievable to me! My face also feels very soft and hydrated (and usually has some dry patches).

Practically perfect in every way
Style: Milky Toner
The results (in combination with other care products) have been amazing! I’m a 37yo trans-woman, who in my late 20s looked like I was in my mid 30s. My skin is much smoother than it used to be (to be fair, in addition to laser hair removal’s results), my tone is more uniform, and with more hydration is fewer wrinkled areas. This is definitely a critical part of my skin care routine, which allows me to need hardly anything for my make-up routine. Value/price is fair, and I have no issue paying that again.

Nice
Style: Milky Toner
I have tried the regular version of this toner years ago and I loved it. It was one of the few products I have used that I could actually notice a visible difference after using. I liked the texture of this one and was excited to try it. I was using Glycolic acid prior to ordering this and wasn't thrilled with my results. This one was nice because it felt nice on my skin and there was definitely no burning even if I use it on an active or open acne spot. There's no scent and the ingredients are fairly good. However, I would be lying if I said I have noticed any visible signs of it working.
