Which ingredient is NOT recommended for use on mature skin and rosacea?

Rosemary Oil is not recommended for use on mature skin and rosacea due to its potential to irritate sensitive skin. Mature skin often requires gentle, calming ingredients that nourish and hydrate, while rosacea is characterized by redness and inflammation. Rosemary Oil can stimulate circulation and has a warming effect, which might exacerbate these symptoms, making the skin feel more sensitive and reactive.

In contrast, ingredients like Jojoba Oil, Hyaluronic Acid, and Vitamin E are considered beneficial for mature skin and those with rosacea. Jojoba Oil is hydrating and closely resembles skin's natural oils, making it unlikely to irritate. Hyaluronic Acid is known for its ability to retain moisture, providing hydration without causing irritation. Vitamin E, with its antioxidant properties, helps soothe and protect the skin, making it suitable for these skin types.
