Provide two examples of ingredients suitable for sensitive skin.

• A. Allantoin and panthenol
• B. Glycerin and allantoin
• C. Panthenol and fragrance
• D. Glycerin and ceramides

Answer: (D)

When choosing ingredients for sensitive skin, focus on hydration plus barrier support while avoiding potential irritants. Glycerin works as a gentle humectant, attracting water to the outer skin layers to keep moisture levels up without causing irritation. Ceramides are essential lipids in the skin barrier; adding them helps rebuild and reinforce this barrier, reducing moisture loss and making the skin less prone to sensitivity.

Together, glycerin and ceramides provide both ongoing hydration and structural protection, which is especially important for sensitive skin.

Fragrance is a common irritant, so any option containing fragrance is less suitable for sensitive skin. While allantoin can be soothing and panthenol can be gentle and moisturizing, they don’t address barrier restoration as effectively as ceramides, especially in the presence of potential irritants.
