Frequently Asked Questions

Your questions answered about iS Clinical EDU and its resources for skincare professionals.

Vitamin A and its derivatives help smooth and refine the skin’s surface, promoting a radiant appearance. Cosmetic formulations use stabilized forms to improve texture and tone without medical activity.

In biological systems, Vitamin A derivatives are converted from retinyl esters to retinol, then to retinaldehyde, and finally to retinoic acid. Cosmetic formulations use early-stage derivatives that remain within the skin’s surface layers to enhance appearance safely.

Different forms offer unique benefits. Retinol and its esters are effective at improving visible smoothness and tone, while encapsulated or time-release versions enhance tolerance. iS Clinical uses balanced forms chosen for cosmetic efficacy and stability.

Keratolytic retinol promotes exfoliation and cell turnover at the surface, while non-keratolytic forms focus on conditioning and improving appearance without visible peeling. iS Clinical’s Retinol+ Emulsions are designed to balance both effects for cosmetic smoothness and comfort.

Retinol+ Emulsions contain encapsulated retinol for gradual release, providing a more intensive resurfacing effect. Pro-Heal Serum Advance+ combines vitamin A derivatives with antioxidants for a gentler, soothing formulation suited for daytime use.
