## Why this fit

- Offers excellent firming and plumping for your dry skin due to peptides like Tetrapeptide-21 and Palmitoyl Tripeptide-1 Acetate, which work synergistically to enhance skin elasticity and reduce the appearance of fine lines. Sodium hyaluronate and squalane further support hydration, addressing dryness and flakiness effectively.
- The formula is highly suitable for dry skin, with glycerin and squalane providing essential humectant and emollient actions to maintain skin barrier function and prevent moisture loss.
- The safety profile is excellent, with no risks of irritation for your dry skin due to the absence of harsh ingredients and the inclusion of soothing components like glycerin and squalane.
