Supatret Gel 0.4% is a topical formulation prescribed to patients with acne problems. Applying it overnight on the acne-prone skin helps treat acne and prevents the formation of new acne. It contains topical retinoid called Tretinoin which when applied on the entire affected area of the face decreases the number and severity of acne as well as heals the existing pimples. Tretinoin is a topical ingredient with an active vitamin A metabolite, which is used to reduce the appearance of blackheads, pimples, age spots, and wrinkles. It is suitable for people with all skin types. The topical medicine must be used with a total skincare and UV rays avoidance program. Supatret gel may make your skin sensitive to sunlight, therefore, it is important to protect your skin by applying sunscreen and wear protective clothing.
