    ► Cosmeceuticals


    Epionce® is a therapeutic line designed to enhance medical and aesthetic treatments. Epionce products are backed by solid science utilizing an effective delivery system for botanical ingredients in specific concentrations to produce visible changes in the appearance and function of the skin. The transport of these elements below the epidermis helps to strengthen the skin barrier while inhibiting the production of damaging inflammatory factors.

    Epionce products offer support in the treatment of rosacea, eczema, psoriasis, and acne. They are also effective to improve the effects of sun exposure, compromised skin, as well as soothe post-procedure and radiation damage.

    Knott Street Dermatology does not keep the entire line in stock. Custom orders can be placed upon request.

    Results Rx® by CosMedix®

    Physician exclusive Results Rx delivers the powerful performance patients expect from a doctor's office. This procedure-specific skincare line utilizes the concept of "chirality": the selection of molecules most recognizable by the skin's receptors. Through this direct communication, these products deliver the purest, most potent ingredients to the skin without irritation or excessive downtime.

    Elta MD® sunscreens help prevent sunburn, as well as decrease the risk of skin cancer and early skin aging caused by the sun, when used with other sun protection measures. Elta MD® sunscreens are formulated with transparent zinc oxide and are non-comedogenic, sensitivity-free, fragrance-free, and paraben-free. All Elta MD® sunscreen products were tested for phototoxicity and showed no adverse effects or unexpected reactions in test subjects.

    ► Eyelash Enhancer

    LATISSE® by Allergan

    LATISSE® (bimatoprost ophthalmic solution 0.03%) is the first and only FDA-approved, science based treatment for eyelash thinning to increase length, thickness, and darkness. LATISSE® users can expect to experience longer, fuller, and darker eyelashes in as little as eight weeks, with full results in about 16 weeks. Continued treatment with LATISSE® is required to maintain the effect; if discontinued, eyelashes will gradually return to where they were prior to treatment over a period of weeks to months (average eyelash hair cycle). Schedule an appointment with one of our providers to discuss if this prescription medication is right for you.

    ► Dry Skin Therapy
    Dry skin is a very common skin condition characterized by a lack of water in the most superficial layer of the skin, the epidermis. Skin is normally kept hydrated by water and lipids (natural oils) that prevent evaporation of water from the skin. Dry weather will draw moisture from the skin, often experienced during the winter months due to low humidity. Repeated wetting and drying of the skin, long hot showers, and harsh soaps will also aggravate dry skin.

    Ointments, creams, lotions, and oils are all effective moisturizers. Ointments can be messy to apply, but work best to keep moisture in the skin. Creams are less messy, last longer than lotions, and are generally preferred by most dermatologists. The following moisturizers are available at Knott Street Dermatology for your convenience.

    ► Jane Iredale: the Skin Care Makeup®
    Jane Iredale® makeup is a line of natural, long-wearing mineral makeup that helps your skin become more balanced. Mineral makeup can conceal almost any skin imperfection, and is created in different formulations and shades to flatter a wide range of skin tones.
