Which ingredient should be avoided by individuals with sensitive skin?

Retinol is a derivative of vitamin A that is commonly used in skincare products for its ability to promote cell turnover, improve skin texture, and reduce the appearance of fine lines and wrinkles. However, it is known to be potent and can cause irritation, redness, and peeling, especially in individuals with sensitive skin. People with sensitive skin often have a compromised skin barrier and react more adversely to ingredients that can cause irritation. Therefore, retinol should be approached with caution or avoided altogether by those with such skin conditions.

On the other hand, hyaluronic acid, vitamin C, and glycerin are typically well-tolerated by most skin types, including sensitive skin. Hyaluronic acid is a hydrating ingredient known for its ability to attract moisture. Vitamin C, despite being acidic, is often formulated in stable forms that are safe for sensitive skin and may even help brighten the complexion and improve skin tone. Glycerin is a gentle humectant that helps to draw moisture to the skin without most potential irritations.
