Quintessential™ takes quinclorac performance to the next level and is an excellent choice if you are going after crabgrass that has invaded your lawn. This is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds, including crabgrass, foxtail, signal grass, and torpedo grass.

  • Up to 90-day control for both broadleaf and grassy weeds
  • Active Ingredient: Dimethylamine salt of Quinclorac 18.92%
  • Unique, patent-pending formulation powered by H-Value Technology, a proprietary performance additive that increases efficacy
  • Great for controlling crabgrass, including the mid-tiller stage of growth
  • Available in multiple sizes *

Product Description:

Quintessential alters the formulation of quinclorac in a way that improves the absorption of the product into the plant. That means faster activity and higher rate load in the targeted weed, as well as improved performance in drought stress or rainfast situations. And unlike any other herbicide on the market, Quintessential demonstrates improved control of crabgrass at all growth stages, including the problematic 3-5 tiller stage. 

This product can be applied to both residential and non-residential turf. Selective control means it doesn’t harm turf.

Quintessential can be applied from seven days prior to seeding and up to twenty-eight days after selected weeds have emerged. The use of methylated seed oil, such as Duo Stick Select is recommended to enhance the effectiveness of the product. If you cannot get methylated seed oil, a non-ionic surfactant can be used.

Target pests include Barnyardgrass, Black medic, Foxtails, Clover, Crabgrass (large & smooth), Daisy, Dandelion, Morningglory, Wild Violet, and more.

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!!

Gentle on my skin and actually brightens. Saw changes around week three.
I picked this up because I wanted something that could help fade a few sun spots without irritating my skin. A lot of dark spot creams feel harsh or overly scented. This one feels rich, calming, and non-greasy, which made it easy to use every night. The texture is smooth and absorbs faster than I expected for a night cream. It doesn’t sit heavy on the skin or leave a film on the pillowcase. After about a week my skin felt more hydrated and even. Around the three week mark I noticed a real difference in brightness and in how even my cheek area looked. The darker spots are not gone, but they look softer and less defined. A few things that stood out: 1. No stinging or peeling which is rare for brightening products. 2. The moisture lasts through the night with no dryness the next morning. 3. Works well under other skincare like serums or retinol. 4. The fragrance is very light and fades quickly. It’s not an instant fix, and anyone expecting overnight results will be disappointed. But if you stick with it, it delivers steady improvement without stressing the skin. For the price, it performs better than some department store creams I have tried. If you want something that brightens tone, softens dark areas, and keeps your skin moisturized through the night, this is a solid option.

Very Good
Eucerin cream is an excellent skincare product, especially for dry and sensitive skin. It provides deep hydration and helps restore the skin’s natural barrier. It absorbs well without leaving a greasy feeling, making the skin soft and smooth. Many people notice improvements in skin dryness and irritation after using it regularly. It is also dermatologist-recommended, which makes it a trusted choice for daily skin care.

Fantastic moisturizer for overnight. Quality and small amt used justifies the $$
Love this stuff! It goes on like silk, and is quickly absorbed. No greasiness. Just enough extra body from the daytime version to be moisturizing all night. As for the dark spot aspect, I don’t really have any spots to correct, therefore I can’t speak to it. This is just an incredible moisturizer for me that doesn’t clog my pores and isn’t greasy..
