if there a difference between these 2 applications

[kukusama]

Is there any difference if i :
spray 2 x IH , 1 of each forearm
vs
spray 2 x IH, overlaying 2 spray on 1 of the forearm

let say if i spray apply 2 spray on my left forearm only, is the effect stronger than i apply 1 spray at both forearm

Not hugely - The greater the surface area of your application the better it diffuses but you will need to move your arms around a bit - in which case the two-arms will have the greatest diffusion.

Thank you so much!

Is more surface area for two sprays better? Yes,more surface area is better. Also, more solvent for the same amount of solute is better. in both cases, better diffusion.

A better question regarding layering sprays is: What happens when I change the order that I layer sprays of different molecules. Does that change the result. The scent, for example.

If you’re speaking from the results of a personal experiment, I bow to your superior data, but in general, diffusion is only linearly proportional to surface area but proportional to the 2nd-4th power of concentration (depending on the system), so higher concentrations diffuse markedly better. I am only speaking of SOLVENT concentrations. Having proportionally more adjuvant carriers [e.g. lower Putative content in the same Androtics base, or adding a cologne] may yield better diffusion, but this is due to mechanisms other than dilution. You’re right about greater surface area, though

Imagine you are cleaning up a small spill of a very stinky substance. You may briefly initially increase the stink by spreading it around, but as you dilute it, it will stink less.

Also remember that body heat/circulation promoting the diffusion will be another factor to consider - So the larger area on both arms will be slightly better than a double app on one.

However, neither will be quite as effective as a smaller app on the (generally) warmer neck/throat area but proximity and moving you arms about may make that-up.

So its not quite as consistent as equal sprays on identical surfaces.

Thank you for the advice! i will keep that in mind
