Clinical Services

West-Michigan-Dermatology-Clinica-Services-page-imageWelcome to West Michigan Dermatology, the new name of the Dermatology Offices of Jack A. Dekkinga, M.D., P.C. Caring, professional service has been a hallmark of our practice since 1982. With locations in Grandville and Holland, West Michigan Dermatology provides expert medical dermatological care focused on conditions of the skin, hair and nails. West Michigan Dermatology specializes in the removal and diagnosis of skin cancer using the highly regarded and advanced Mohs microsurgical technique.

At West Michigan Dermatology we treat an array of common skin conditions including acne, moles, warts, hair loss, eczema, psoriasis, rosacea and melanoma. We also offer cosmetic procedures and products through The Skin Revitalizing Center, located in the same building as our Grandville office.

From our board-certified physicians, to our highly-trained PAs, estheticians and staff – all of us share a common philosophy of care for our patients. We subscribe to a belief-driven philosophy of practice that tells us the most important things we can provide, in addition to quality medical care, are a listening ear, a smile and an understanding heart. We are dedicated to helping people, and regard it as a blessing when we can do so.

Blu-U is a unique, non-drug therapy that can be effective in treating moderate acne. When sebaceous glands just beneath the surface of the skin produce extra amounts of oil, this can clog the pores to the skin, trapping the oil. P. acnes bacteria thrive in these clogged pores, quickly leading to irritation of the skin and the formation of a “pimple.” Blu-U is a great alternative for those who are uncomfortable taking antiobiotics or are unhappy with their current antibiotic treatments.

Blu-U is light and gentle, using blue light to kill the P. acnes bacteria in the skin. During treatment, a patient needs only to sit close to the blue light for a short time – usually 16 minutes once or twice per week. The length of treatment varies depending on the severity of acne and will be discussed with you during your initial appointment.
