Soap with the best post shave

Hyaluronic Acid is a natural component, works in deep.
Polyglutamic Acid is a synthetic product, works on surface ...

How "deep" a moisturizer goes is irrelevant ...

For you, for sure.
Unrefined and pure.

Looking at the big picture, endogenous components as Hyaluronic Acid play a role in a balanced system.
Not just moisturizing, but helping the matrix to control density and biosyntesis.
Focus on the physiology, not just on chemistry.
Human Skin is not potato skin.

To answer the OP question of best post shave in a soap:
1) Grooming Dept (lamb tallow/donkey milk formula)
2) A&E Kaizen

I've tried a lot of soaps and those two are my #1 & #2 in order for post shave specifically, but also in overall performance.
I've not tried "Ethos" soap though.

Wow I hadn’t even heard of Ethos or Cutting Edge before coming here, so I’ll have to try them out. My favorite purely for post is DG milksteak. The other bases I’ve tried have probably caught up and are close (NO v3, Talbot v3, GD kairos) but milksteak was the first soap that truly wowed me with the post feel.

Note: I havent tried Ethos (YET, as I will as soon as the site is up), so for now the best post shave goes to the following in order: DG Milksteak, Wholly Kaw Siero, B&M Excelsior, A&E and Zingari Man.

Another vote for Mystic Water. Jusr the right post-shave. Soft, supple, smooth, but never greasy and it never feels like it left a film on your face.

Currently, my favorite post shave feel is Talbot v3. It’s truly incredible. It’s the very first time I honestly felt that my face wouldn’t benefit from a post shave product.

I just used this tonight and it is incredible. 
My wife says she's jealous of my soft skin.

Just ordered CuttingEdge and Mystic Water, haven't tried them before.
My faves are Ethos and GroomingDept Otium.

I tried both CuttingEdge and Mystic Water both with peppermint scents.

I paid $20 + shipping to CuttingEdge, it is written 3.5oz but I received around 4 to 4.5 oz. 
I really like the soap, it has very good post-shave feeling. 

I paid less than $15 + shipping to 4 oz. Mystic Water, I really surprised with the results.
It is an excellent soap and you can get refill under $12. Excellent performance and post-shave.

Best post-shave is easy for me , Ethos wins by a wide margin.
