- Grapeseed Carrier Oil tightens and tones the skin, protects against sun damage, and reduces the appearance of blemishes, wrinkles, and stretch marks. Used on skin, Grapeseed Oil cleanses the pores and balances oil production, thereby reducing future acne breakouts - Mixing a drop of grapeseed oil in your favorite moisturizing face and body creams helps to seal the moisture into your skin. If you'd prefer, you can heat grapeseed oil slightly by putting some in your palms and rubbing your hands together. Apply a generous amount to your skin as a moisturizing mask.
