Jonathan Green’s Mag-I-Cal Plus for Lawns in Alkaline & Hard Soil contains sulfur and calcium sulfate dihydrate which lowers soil pH, is important to cell development and is vital to many grass plant functions. Poor soil that is hard and compacted is often the problem when it comes to growing a great lawn. When soil is too alkaline and compacted, air, water and nutrients cannot get down to the roots and the grass will not grow properly. Lawns thrive in slightly acidic to neutral soil with pH levels between 6.2 and 7.0. In soils with pH readings of 7.0 to 9.5, weeds thrive and the grass becomes light green and spindly. Additionally, Mag-I-Cal Plus helps to break up clay and compacted soils. This improves root penetration and promotes growth by increasing biological activity and releasing nutrients trapped in the soil.

Satisfied
I’ve been hearing all about the benefits of snail mucin for skin care, and now after trying Jasclair snail mucin hydrating serum for post derma-planing, it is easy to understand what all the hype is about when it comes to snail mucin. After derma-planing, it is super hydrating and soothing to put on, and my skin retains that moisture long after. But although it’s great for after derma-planing, it works just as well as a daily serum. For anyone wondering - yes it is a little bit slimy, but it’s more just out of the ordinary for what one is used to with a serum, not anything excessive. The smooth hydrated texture of my skin afterwards it’s perfect for makeup application and this serum works well underneath my make up, at least in part because it absorbs so well. A little bit goes a long way and this is now a must have as part of my beauty routine. I would highly recommend this snail serum after derma-planing and overall skin rejuvenation.

Great results
Love using this item at night. It’s kind of thick but if put on before bed it is all soaked in by morning. Face is so smooth after using this product before bed. Easy to use and completely clear in color.

Ok
The Snail Mucin hydrating serum is soothing and effective, ideal for use after dermabrasion or other skin treatments. It deeply moisturizes, promotes skin healing, and helps reduce redness and irritation. Lightweight and fast-absorbing, it leaves the skin soft, refreshed, and rejuvenated.
