    Can I use Summer C on acne-prone skin?

    100% of volunteers said the product did not cause breakouts or clog pores*** Niacinamide and White Willow Bark Extract used in this formula supports the care of acne-prone skin. Additionally, Meadowfoam Seed Oil, Avena Sativa Kernel Extract, Pseudoalteromonas Ferment Extract, and Clay Sage Oil regulates the production of sebum. This product is formulated to be non-comedogenic and maintain a balanced skin microbiome. A balanced skin microbiome is important because it helps maintain the health of the skin and protects it from pathogens. Research suggests that imbalances in the skin microbiome can contribute to the development of acne. Acne-causing bacteria, such as Propionibacterium acnes (P. acnes), can overgrow in areas with a disrupted microbiome, leading to inflammation and the formation of pimples. Additionally, the skin's natural oil production can be disrupted, leading to clogged pores and further acne breakouts. However, it is always advisable to consult with a dermatologist or healthcare professional before using a new product, especially if you have acne-prone, skin or any other specific skin concerns. ***A third-party laboratory conducted studies on 25 women ages 24 to 45 for 28 days under a dermatologist’s supervision. Results are based on the volunteers’ observations.

    What concentration of actives do you use?

    Our formula consists of active ingredients in a concentration level that is both effective and safe for the health of your skin barrier and skin microbiome. These concentration levels are advised by the manufacturer of each component and are grounded in scientific evidence that demonstrates specific benefits for the skin.
    While we often seek instant results and opt for products with the highest concentration of ingredients, this can sometimes cause harm instead of good for our skin. For example, Niacinamide has been shown to be safe and effective for the skin at a concentration of 2-5%, but higher concentrations can weaken the skin barrier. Instead of just focusing on concentration, we advocate for a holistic approach to skincare. We recommend a consistent and deliberate skincare routine, rather than constantly overloading your skin with a high concentration of active ingredients. By adopting a more mindful approach to skincare, you can revitalize your skin barrier and enjoy long-lasting benefits for your skin's overall health.

    Can I use it while pregnant?

    When used properly, our products are safe during pregnancy and while nursing. Although there are no specific safety tests for products during pregnancy and nursing, there is a substantial amount of information supporting the safety of products when used as directed. If you have any concerns, we recommend that you consult your doctor.
