    Size
    Aida says: The most concentrated finishing serum for older skin, skin with wrinkles, loose skin, and tired and dull skin. Use it morning and night on top of cream. A finishing serum is important for sealing the serums and cream underneath and protecting skin from environmental damage. You can also incorporate the finishing serum into your makeup by mixing it foundation or any tinted makeup.

    Best finishing serum for menopausal skin!

    Le Grand Serum is the best finishing serum I've ever used. Even when I try something new I always come back to Le Grand. There's nothing like it for sealing in all that comes before it. The protective barrier it creates saves my sensitive skin from the harsh arid desert environment. Pricey but absolutely worth it!
