Frequently Asked Questions:

What is Humic Acid?

A naturally occurring substance from decomposed organic matter that revitalizes soil and supercharges nutrient absorption.

Why is it called "Humic Acid"? Is it dangerous?

Great question—the word “acid” in “humic acid” sounds stronger than it really is. But don’t worry—this is not a harsh chemical like battery acid or vinegar.
Humic acid is a completely natural substance that comes from ancient organic matter, like decomposed plants, found in the earth. It’s called an “acid” because of its chemical classification, not because it’s corrosive or harmful. In fact, it’s safe for all plants, pets, and people when used as directed.
Think of it like vitamin C for your soil—it helps unlock nutrients and feed the living biology in the ground that your plants need to thrive. Many organic gardeners and farmers use it regularly to improve soil health and boost plant growth safely and effectively.

What is Humic acide good for?

Plants only absorb a fraction of the fertilizer you apply. The rest is often locked in the soil or washes away. Humic acid changes that. It binds nutrients in a form that roots can absorb, naturally enhancing fertilizer efficiency and soil vitality.

Is this product safe for pets and kids?

Yes! Our humic acid is 100% organic and derived from natural sources. It contains no harmful chemicals and is safe when used as directed around pets, children, and edible plants.

How often should I apply it?

For most plants, apply once per month during the growing season. For problem soils or heavy feeders, apply every 2–3 weeks.

Can I mix it with other fertilizers?

Absolutely. Humic acid actually improves the efficiency of other fertilizers, helping your plants absorb more nutrients with less waste.

What does it do for my soil?

It improves soil structure, boosts microbial life, and enhances the availability of nutrients, creating a healthier and more productive growing environment.

Is this just for outdoor use?

Nope! It's great for indoor potted plants too. Just dilute and apply to the soil like you would outdoors.

A Staple in Skin Care Routine
Style: Milky Toner
This toner has become a staple in my skincare routine. I have sensitive skin and a lot of products tend to cause irritation or redness, but this one has been incredibly gentle from the start. My skin always feels soft, calm, and hydrated after using it. The texture is lightweight with an almost soapy feel at first, but it absorbs quickly and never leaves my skin feeling greasy or heavy. It layers well with the rest of my skincare and works great both morning and night. I also appreciate that it gives results similar to more expensive brands without the high price tag. Definitely one of the better affordable skincare products I’ve tried.

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).
