With all of these benefits has come some myths and mistruths circulating around and with the launch of the new Powerful-Strength Line-Reducing Concentrate with heightened Vitamin C and added ingredient of Hyaluronic Acid, it’s important to learn the facts on Vitamin C and how we at Kiehl’s use it.1
As Pioneers in Vitamin C skincare for more than 13 years, Kiehl’s has extensive knowledge of this ingredient, being recognized as having expertise in Vitamin C formulations, incorporating it at its most beneficial concentrations. Learn more about Vitamin C and how it can achieve your skin care goals with a Healthy Skin Essentials routine.
Fact: Not All Vitamin C’s are created Equal
Although there are different forms of Vitamin C, with overlapping benefits, Kiehl’s uses three key forms of Vitamin C. Pure Vitamin C (also known as L-Ascorbic Acid) to reduce lines and wrinkles, Vitamin Cg to minimise the appearance of lines and wrinkles over time and Activated C for brightening and correcting skin discoloration. Each of Kiehl’s Vitamin C serums and cream effectively incorporates a form of topical Vitamin C that is carefully selected to maximize its targeted efficacy.
Fiction: The More Vitamin C the Better
When products have too high a concentration level of L-Ascorbic Acid, it can cause skin irritation. However, Kiehl’s selects its Vitamin C concentrates at levels that are both effective and gentle on the skin. Our products are then dermatologist-tested for safety, proving the suitability of our formulas for all skin types, including those with sensitive skin.
Fact: Your Skin Needs Topical Vitamin C
Just as Vitamin C is an important part of our diet, it is also an important part of keeping your skin healthy. Vitamin C benefits for skin include supporting collagen production and protection against free radicals. Using a balanced Vitamin C facial serum every day will ensure that your skin soaks up all of the benefits of this powerful ingredient.2
Fiction: Vitamin C causes skin sensitivity to the Sun
On the contrary, topical Vitamin C has actually been proved to be a second line of defence against harmful UVA rays while also helping to boost skin’s antioxidant defenses. We recommend applying a Vitamin C serum in the morning before applying your daily SPF product.3
Fact: Vitamin C Products Benefit All Types of Skin
The benefits of topical Vitamin C can be enjoyed by all skin types, including sensitive and dry skin. Vitamin C serums can also help to correct dark spots and post-acne marks as used in our Clearly Corrective Dark Spot Solution.
Our serums containing Vitamin C pair well with certain other serums or concentrates such as our Kiehl’s Midnight Recovery Concentrate or our Daily Reviving Concentrate. Speak with our friendly Kiehl’s Customer Representatives to find complementary serums which are right for you. Visit our store locator to see your nearest store.
Fiction: Vitamin C Serums are Not for Sensitive Skin
At Kiehl’s, our Vitamin C serums are formulated to be gentle enough for sensitive skin types. When first beginning to use facial Vitamin C skincare products, start by applying once a day and gradually build to twice a day. Vitamin C will create a gentle warming sensation on the skin on application which is perfectly normal and not a reaction or sensitivity. This sensation will cease quickly but the Vitamin C will continue to work beyond that. Always consult with your dermatologist when incorporating new skincare products into your routine.
Fact: Store Your Vitamin C Serum in a cool dry place
Store L-Ascorbic Acid serums like Powerful-Strength Line-Reducing Concentrate in a place other than your bathroom cabinet to avoid contact with humidity. Also, keep out of direct sunlight. Additionally, the best Vitamin C serums are kept in dark-coloured or amber bottles that effectively protect the formula from light.
Fact: Apply Vitamin C Serums Before Your Moisturiser
After you cleanse and tone your skin, apply a thin layer of Vitamin C serum. Smooth it on morning and night before your moisturizer to lock in Vitamin C benefits for skin.

Forms of Vitamin C
Pure Vitamin C L-Ascorbic Acid or Pure Vitamin C is a powerful skincare ingredient. This potent form of Vitamin C easily absorbs into skin and begins working immediately. A dermatologist-recommended ingredient, L-Ascorbic Acid is frequently used in anti-aging products to improve radiance and skin texture while diminishing the appearance of fine lines, wrinkles and crow’s feet. Kiehl’s Dermatologist Solutions Powerful-Strength Line-Reducing Concentrate uses 10.5% of Pure Vitamin C. L-Ascorbic Acid is also found in Powerful-Strength Line-Reducing Eye-Brighteing Concentrate Vitamin Cg Ascorbyl Glucoside is a potent derivative of Vitamin C that boosts collagen production, provides antioxidant protection and helps to minimize the visible signs of aging. Vitamin Cg activates once absorbed into skin to boost Vitamin C activity overtime. In Kiehl’s Powerful-Strength Line-Reducing Concentrate, 2% of Vitamin Cg is included to enhance the efficacy of Vitamin C benefits over time. It is also found in the Facial Fuel Energising Moisture Treatment for Men.4
Activated C Activated C is a next-generation Vitamin C derivative that is highly efficacious. This powerful form of Vitamin C penetrates skin and is proven to effectively fade acne marks and age marks and reduce skin discolorations.
