Questions, answered plainly

Before you add another step.

Is glycerin only for dry skin?

No. Formulas use it in light and rich textures alike, so the whole formula matters more than the one ingredient.

Can I use glycerin every day?

It is common in daily-use formulas. Follow the directions on the finished product.

Is glycerin the same as a face oil?

No. Glycerin is a humectant, while oils are generally used as emollient or occlusive components.
