DermaHarmony, also known as D3 Development, Inc., is a Maine-based skin care product business whose origins date to 1997. The company makes soaps, cleansers, and solid shampoo bars for problem skin, including products formulated with zinc pyrithione, sulfur, salicylic acid, and benzoyl peroxide. Its products are positioned to help with the symptoms of psoriasis, acne, seborrheic dermatitis, eczema, and severe dandruff, and are intended to treat, prevent, or cure a medical condition only when identified as an OTC drug. DermaHarmony began by making zinc pyrithione and salicylic acid products for the psoriasis community, and its approach also reflects an effort to lessen environmental impact.
