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.

So lightweight, so smooth
I was looking for a retinol eye cream and decided to try this since I liked this brand before. The texture is super lightweight and absorbs well, and my makeup doesn’t pill at all after using it. Not sure yet about long-term wrinkle results, but it keeps my under-eye really hydrated and smooth. I’ve also been using it on my smile lines. lowkey excited to see more results!

Helped a bit with barrier, but it must be used very sparingly, and didn't improve fine lines for me.
I had mixed feelings about this eye cream. On paper, the combination of ingredients such as retinol, niacinamide, and centella sounded promising, especially for targeting texture and supporting the skin barrier. However, in practice, I found the formula to be a bit too strong for my sensitive eye area. I had to be very careful not to apply it too close to my eyes to avoid irritation. The cream is very thin and lightweight, and I found that it did absorb well without leaving too much of a greasy residue once applied. After about two weeks of consistent use, I did notice some positive changes. The skin under my eyes felt slightly more elastic, and my skin barrier seemed to be benefiting overall, which I appreciated. That said, I didn’t see any real improvement in fine lines or firmness, which is one of the main reasons I reach for an eye cream with retinol in the first place. The price point is definitely affordable, but it also feels like a case of getting what you pay for. While it’s not a bad product, it didn’t stand out enough for me to consider replacing my regular eye cream. At the end of the day, skincare is a long game. What we do now often shows up years down the line, so I do think it’s worth investing in higher-quality formulas when possible. For me, this one was just okay: some mild benefits, but ultimately unremarkable.

Pleasantly surprised
I’m two jars in and love it. I do use Botox, retinol, a good face wash, wash moisturize twice daily, etc etc. I struggle with moisturizer because I’m prone to breakouts. Idk what it is about this one but my skin loves it. It feels refreshed and soft. Added bonus, my eyebrows and lashes have gotten longer and darker quick! Obviously we all respond differently to products but I’ll be keeping this in my rotation

A thick and rich cream that smooths on nicely!
So I jumped on the Korean skincare bandwagon and decided to purchase some of the DR MELAXIN Products to try! I read many good reviews and decided it was worth the money. This first product is the Dr Melaxin Calcium cemenrete calcium volume cream. It comes in a 1.76 ounce glass jar. On the label there is a lot of word descriptions so I will add a few: Ex volume firming, rebornic 10,000 ppm hydrolyzed elastin and collagen extract. I have photographed label for viewing. The directions indicate to "apply a small amount of cream onto your face especially around the under-eye area". I found the cream thick and rich and I used it in addition to another Dr Melaxin neck and face product so I concentrated on only neck and under eye area. It is neutral in scent and is very thick so it feels like it is absorbing nicely. I have been using it for about a month now and have definitely noticed some improvement in the neck area so i will continue to use and layer with other products. I do recommend this line as the ingredients seem effective so far!
