Product Description:
Humic12 liquid humic acid product is an excellent addition to any fertilizer program for correcting soil issues. Humic acid is essentially the final remains of organic matter, primarily plant material that has decayed over time and broken down into its simplest form by microbes. If you think poop is organic, natural, and good for plants, then think of humic acid as microbe poop. Super small, super-rich, and super for your soil (but no foul smell). 

Humic acid is carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur, and the only reason it’s acid is that it’s a hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. And that is what makes humic acid so awesome!

It is known as a “chelator” (pronounced Kee-Lay-Tor), which in layman’s terms just means that it helps other nutrients become more available to the plants to be utilized. Think of it as a bridge between nutrients and your turf’s roots. To put it simply, applying humic acid to your lawn and watering it into your soil helps the turf roots extract more of the naturally existing nutrients from the soil AND makes the fertilizer you apply more efficient. If we were talking in automotive terms, it would be like adding a shot of nitrous to increase your speed.

The process of N-Ext Humic12 stands out against the competition. Their “long brew” technique using high-quality oxidized lignite, allows for a cleaner, more flowable product with enhanced biological activity.
The benefits of N-Ext Humic12 are:

  • Increased root growth
  • Increased chlorophyll content
  • Increased nutrient uptake
  • Improved soil structure
  • Improved plant quality

Greasy but light
It's very lightweight and is definitely hydrating it's lightly greasy after its dry and it is not matte but has a dewy shine to it , I have tried many sunscreens and settled on this one as it just has a nicer feel to it and is easier to apply everyday, it goes on quickly and leaves no white streaks at all Its more watery than thick And does NOT peel whatsoever I Would definitely recommend this as a daily Face sunscreen if you not mind the shine it has to it. Its convenient Yet the bottle is small and last only about a 1 to 3 weeks depending how many times you use it To bad They DO NOT MAKE A BIGGER SIZE

Hydrating sunscreen
This is a great sunscreen for dry sensitive skin, even combination skin specifically if you’re using acne products that can dry out your skin. My dermatologist recommended this to me due to my rosacea and dry flaky skin. It helped me maintain my skin moisturize during the day, also adds a healthy glow to the skin. It has a liquid consistency which I love cause it makes it so much easier to blend and absorbs faster into the skin. I wouldn’t recommend so much for oily skin though, it can make you look greasy really quick!!

Delicious flavors and reliable sun protection
Scent: Coconut, Banana, Watermelon, Size: 0.15 Ounce (Pack of 1)
These Sun Bum SPF 30 lip balms are perfect for anyone looking to protect their lips from the sun while keeping them smooth and moisturized. I appreciate that each tube in this variety pack provides broad spectrum SPF 30 protection with soothing aloe and vitamin E, which nourish my lips instead of just sitting on the surface. The coconut, banana, and watermelon flavors are deliciously tropical without being overly sweet, and the balm glides on easily without leaving a heavy or greasy feel. I also love that the formula is reef-friendly and free from harsh chemicals like oxybenzone and octinoxate, so I can use it confidently at the beach or on the slopes. Overall, this set has become my go-to for daily lip care and sun protection, and I would gladly reorder it or give it as a thoughtful gift to friends and family.
