“We wanted to formulate a retinol product that could be used every day from the start with minimal discomforting effects, while still offering powerful anti-aging skin benefits. Our formula includes peptide to further support and sustain the repair benefits of retinol, and ceramides that release vital skin barrier lipids to help build retinol tolerance and prevent against dryness. The precise dose of retinol can then be effectively delivered into skin to begin providing benefits without over-accelerating cell turnover or disrupting the skin barrier. The results are the maximum efficacy of retinol, with minimal to no discomfort.”

Frequently Asked Questions
Can retinol serum be used under eyes?
While most retinol serums are too irritating to be used under eyes, our Micro-Dose Anti-Aging Retinol Serum is formulated with ceramides and peptides to help fortify the skin barrier thereby promoting skin tolerance to retinol, including the delicate skin area around the eye. The micro-dose amount of Pure Retinol also ensures the skin experiences minimal irritation.
Can retinol serum be used in the morning?
While most retinol serums are recommended for night usage, our Micro-Dose Anti-Aging Retinol Serum utilizes advanced micro-dosing technology – a scientific skincare innovation that ensures Pure Retinol is administered to the skin in a precisely calibrated dose. This promotes a gradually accelerated rate of surface skin turnover. This coupled with the ceramides and peptide in the formula ensures skin is fortified and tolerant to retinol, making Micro-Dose safe for day-time use. Make sure you always protect your skin against skin-aging UV damage by using Super Fluid UV Defense Daily Facial Sunscreen SPF 50+
Can you use retinol serum and hyaluronic acid together?
Hyaluronic acid is known for its ability to pull moisture into the skin. Hyaluronic acid will hydrate the skin while retinol will help the skin renew itself more rapidly. To minimize any side effects such as redness, drying, or peeling, retinol may be used in partnership with hydrating serums, such as Vital Skin-Strengthening Hyaluronic Acid Super Serum.
What age should you start using a retinol serum?
Retinol can be used as early as the 20s where it can help maintain the skin’s youthful look. As one ages, retinol is an important ingredient for any anti-aging routine as it can help improve the visible signs of aging while also delaying the appearance of more advanced signs of aging.
Can you use a retinol serum and Vitamin C together?
Vitamin C is a powerful antioxidant that protects the skin by neutralizing free radicals. Using Vitamin C and Retinol will enhance any anti-aging routine, but they should not be used together. We recommend using a Vitamin C product, such as Powerful-Strength Vitamin C Serum, in the morning and a retinol serum at night. This will avoid skin sensitization while ensuring that Vitamin C defends, protects, and supports collagen production, while retinol renews skin cells and stimulates collagen.
Can you use a retinol serum and AHAs together?
AHAs, or Alpha Hydroxy Acids, are chemical exfoliants that brighten and clear your skin. They are considered an “active” ingredient. Avoid using additional active ingredients at the same time as retinol to avoid skin sensitization. AHA products, such as Ferulic Brew Antioxidant Facial Treatment with Lactic Acid
may be used during the daytime.
Does retinol serum help with anti-aging?
Topical retinol has been a dermatologist preferred ingredient for anti-aging treatment since it was first offered over 50 years ago. It is considered a highly effective topical ingredient capable of treating and visibly improving a wide range of skin aging signs including lines, wrinkles, firmness, texture, visible pores, radiance and photodamage. It can also help to maintain youthful-looking skin as well as delay the onset of advanced skin aging signs.
CAN I USE RETINOL ON MY BODY?
Yes, you can use our retinol on your body. However, it is important to start slowly and gradually increase the amount of retinol you use over time to reduce the risk of irritation. It is also important to use a retinol product that is specifically formulated for the body. Our gentle retinol serum is perfectly suited to avoid retinol reactivity while nourishing the skin with Collagen Peptide. It’s best thoroughly tested and is suitable for use on the hands, neck, & chest.
WHAT IS THE DIFFERENCE BETWEEN RETINOL AND TRETINOIN?
Retinol and tretinoin are both forms of Vitamin A, but they have different effects on the skin. Retinol is a gentler, yet still very effective, form of Vitamin A that is often used in over-the-counter skincare products. It can help to improve skin texture and reduce the appearance of fine lines and wrinkles. Tretinoin is a more potent form of Vitamin A that is only available by prescription to treat more advanced cases of acne, hyperpigmentation, and other skin conditions.
CAN I USE THIS RETINOL IF I HAVE ACNE?
Kiehl's retinol serum is designed primarily for anti-aging. It is formulated with a low concentration of retinol and is suitable for people with sensitive and acne prone skin.
CAN I USE RETINOL EVERY DAY?
For typical retinol serums, it is generally recommended to start by applying them every other day or once a week and gradually increase your usage as your skin adjusts. Because our micro dose formulation was designed with sensitive skin in mind, it can be used daily with visible results with minimal visible redness, dryness, or peeling.
