Panthenol (also called pantothenol) is the alcohol analog of pantothenic acid (vitamin B5), and is thus a provitamin of B5. In organisms, it is quickly oxidized to pantothenic acid. It is a viscous transparent liquid at room temperature. Panthenol is used in pharmaceutical and children's products as a moisturizer and to hasten wound healing.

Understanding how deep skincare ingredients can reach
Outermost protective layer
Living skin cells, no blood vessels
Collagen, elastin, blood vessels
Smaller molecules (under 500 Da) penetrate deeper. The 500 Da rule states that molecules larger than this rarely penetrate beyond the stratum corneum.
Delivery systems like liposomes, nanoparticles, and certain solvents can help larger molecules penetrate deeper into skin layers.
Damaged or compromised skin barriers allow deeper penetration, while intact barriers are more selective about what passes through.
Introduce at the typical OTC concentration range of 1% - 5%. Higher percentages should be reserved for skin that has already built significant tolerance.
Usually suitable for PM routines. If applying in the AM, follow with a broad-spectrum SPF 30+ to shield active skin.
