Brief Summary:

The purpose of this study is ascertain the efficacy and safety of Clindamycin

Phosphate 1.2% and Tretinoin 0.025% in the treatment of Acne and Post

Inflammatory Hyperpigmentation in patients with skin of color.

Condition or disease Intervention/treatment Phase
Acne Drug: Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel Phase 4

Detailed Description:

Acne is a chronic disorder of the pilosebaceous glands characterized by

inflammatory papules, pustules, opened and closed comedones, cysts and

nodules. Post inflammatory hyperpigmentation is a condition in which an

inflammation from a disease such as acne, trauma, or abrasion results in areas

of the skin with increased melanin content compared to the surrounding skin.

There are several treatments available for acne, which include benzoyl

peroxide,antibiotics (topical or oral), and topical retinoids (tretinoin,

tazarotene, adapalene). Combination therapy, such as topical retinoid and

clindamycin, has been shown to be more effective than monotherapy in

addressing all pathogenic factors of acne.
