Factors Affecting Penetration
Molecular Weight
Smaller molecules (under 500 Da) penetrate deeper. The 500 Da rule states that molecules larger than this rarely penetrate beyond the stratum corneum.
Formulation
Delivery systems like liposomes, nanoparticles, and certain solvents can help larger molecules penetrate deeper into skin layers.
Skin Condition
Damaged or compromised skin barriers allow deeper penetration, while intact barriers are more selective about what passes through.
