A recent study looked at the
effect of collagen hydrolysate — a grass - fed protein collagen supplement
similar to one we recommend to many of our patients —
on skin elasticity,
skin hydration and
skin roughness.
But if microblading seems daunting, Jalaf says you can achieve a
similar effect with tinting: «By leaving the tint
on for longer, it tints the
skin a little, giving the illusion of fuller brows while covering up patches,» she explains.
Before allowing the temperature to respond, we can consider the forcing at the tropopause (TRPP) and at TOA, both reductions in net upward fluxes (though at TOA, the net upward LW flux is simply the OLR); my point is that even without direct solar heating above the tropopause, the forcing at TOA can be less than the forcing at TRPP (as explained in detail for CO2 in my 348, but in general, it is possible to bring the net upward flux at TRPP toward zero but even with saturation at TOA, the nonzero
skin temperature requires some nonzero net upward flux to remain — now it just depends
on what the net fluxes were before we made the changes, and whether the proportionality of forcings at TRPP and TOA is
similar if the
effect has not approached saturation at TRPP); the forcing at TRPP is the forcing
on the surface + troposphere, which they must warm up to balance, while the forcing difference between TOA and TRPP is the forcing
on the stratosphere; if the forcing at TRPP is larger than at TOA, the stratosphere must cool, reducing outward fluxes from the stratosphere by the same total amount as the difference in forcings between TRPP and TOA.
