How to Apply:
- After Cleansing and toning, apply 1-2 pumps over entire face - twice daily (avoiding the eye area)
- As the formula blends into the skin, you may experience a feeling of warmth. This sensation is normal
- Follow with your usual facial oil and/or moisturizer
- *While our formula does not sensitize skin to the sun, we always recommend the daily use of a broad-spectrum sunscreen as the cornerstone of every healthy skincare regimen

Vitamin C Myths Debunked
- Your Skin Needs Topical Vitamin C - Not Just Oranges
Fact: "While skin cells do not have the ability to produce Vitamin C, the ingredient is an essential part of collagen production. Therefore, in addition to eating a diet rich of the potent anti-oxidant, it is important to apply a topical Vitamin C to return skin to a healthy state and reduce the appearance of aging. " Dr. Geyer Kiehl's consulting Dermatologist - Vitamin C is For Any Skin Type, at Any Age
Fact: "I recommend Vitamin C products not only to my patients who are looking for solutions to correct signs of aging, but also those who want to prevent the aging process from starting early. Vitamin C is one of the best known anti-oxidants, protecting skin against UV damage caused by free radicals."Dr. Geyer Kiehl's consulting Dermatologist - Topical Vitamin C Should Only Work at Night
Fiction: "Before my patients leave their door, I tell them to apply an anti-oxidant rich product and an SPF 50 or higher. Vitamin C is a great anti-oxidant that provides a second layer of defense after sunscreen by neutralizing free radicals that can damage skin, accelerating signs of aging."Dr. Geyer Kiehl's consulting Dermatologist
