Does Jergens Natural Glow actually work?

How Jergens Natural Glow actually builds color

Here's the mechanism buried under the glow, let's dig it out. The active ingredient doing the actual tanning is dihydroxyacetone, DHA, a sugar that reacts with the amino acids sitting in the dead outer layer of your skin, the stratum corneum. That reaction, a version of the browning you see on toast, produces melanoidins, brown pigments that sit on the surface rather than penetrating anywhere. Because Jergens mixes a low dose of DHA into a daily lotion instead of a concentrated tanning spray, each application only darkens you a little, which is exactly why the color builds gradually over about a week instead of showing up orange overnight. Layer it daily and the pigment accumulates in step with your skin's natural shedding cycle, so it fades the same way it arrived, evenly, instead of patchy. That part is straightforward chemistry and it works the way the label says. The collagen, elastin, and green tea blend is a different story. Those molecules are far too large to reach the fat and connective tissue that actually cause cellulite's dimpled look, so what you're getting is a moisturizer that plumps and smooths the skin's surface, temporarily softening how the texture reads under light. That's a real cosmetic effect, worth having, it's just not a structural fix, and it won't survive past your next shower the way the tan color will.
