L'Oréal Paris Age Perfect Le Duo Defying Serum - Collagen Peptide Booster + Vitamin B3 & C*, 15ml

The serum combines a collagen peptide booster to smooth wrinkles and improve firmness with vitamins B3 and C to brighten dull skin and even tone, promoting a more youthful and refreshed appearance.

It is recommended to use the serum twice daily, in the morning and at night, as part of your regular skincare routine.

Yes, this serum is designed to complement your existing skincare routine and can be used with other L'Oréal Paris products.

The serum has a silky, lightweight texture that absorbs quickly into the skin without leaving any heavy residue.

The sophisticated pump is designed to release two expertly balanced serums simultaneously from separate chambers when pressed evenly, ensuring optimal performance and integrity of each formula.

It is generally suitable for adult skin. However, if you have sensitive skin, it is recommended to perform a patch test first.

With twice-daily use, a 15ml bottle typically lasts approximately 3-4 weeks, depending on the amount of product dispensed per application.

Ensure you are pressing down evenly on both sides of the pump simultaneously. If the pump appears clogged, gently wipe the nozzle with a dry cloth.

Discontinue use immediately. Perform a patch test on a small area of skin before reintroducing the product to the full face. Consult a dermatologist if irritation persists.

You may be using too much product. Try using a smaller amount, equivalent to one pea-sized drop, and ensure it is spread evenly and massaged in until absorbed.

Consistency is key. Ensure you are using the serum daily, both morning and night, as directed. Results can vary based on individual skin types and concerns. Allow at least 4-8 weeks of consistent use.
