Skin irritation and inhalation toxicity of biocides evaluated with reconstructed human epidermis and airway models.

Biocides are widely used in household products. Humans are exposed to biocides through dermal, inhalational, and oral routes. However, information on the dermal and inhalational toxicity of biocides is limited.

Lysates of a Probiotic, , Can Improve Skin Barrier Function in a Reconstructed Human Epidermis Model.

The main function of the skin is to protect the body from the external environment. The barrier function of the skin is mainly provided by the stratum corneum, which consists of corneocytes bound with the corneodesmosomes and lamellar lipids. Skin barrier proteins like loricrin and filaggrin also contribute to the skin barrier function.
