The drug Philefasol is effective in treating acne, especially good for patients with oily skin, thanks to the pharmacological mechanism of the above ingredients. Tretinoin is a drug that causes the skin to peel off the stratum corneum, shortens the renewal time of epidermal cells and stimulates the regeneration of connective tissue. Tretinoin acts on hyperkeratinization that causes sebaceous stasis (the cause of acne microcysts and nuclei). Thereby eliminating open caviar and microcysts, and also preventing their formation. The drug also has the effect of promoting the progression of nodules and pustules by reducing the inflammatory response caused by saprophytic bacteria and some components that irritate the sebum. Tretinoin when applied to the skin has many different effects on cells such as stimulating cell division, promoting renewal of epidermal cells, inhibiting the formation of keratin or stimulating the regeneration of connective tissue. Drugs have the ability to prevent, even shrink skin tumors. The drug acts directly on cellular lysosomes, releasing proteolytic and hydrolytic enzymes. When used topically, tretinoin is poorly absorbed. Most of the drug remains on the surface of the skin in situ, a small amount penetrates the epidermis and dermis, and low plasma concentrations cannot be detected.

The extent of transdermal absorption of tretinoine or of retinoic acid, although varies depending on the area of application or duration of treatment... but is still very low when used in therapeutic doses. In terms of metabolism, tretinoin is rapidly metabolized within 48 hours. Erythromycin is a macrolide antibiotic with bacteriostatic activity against all bacteria causing acne mainly Gram-positive and Gram-negative bacteria and others including Mycoplasma, Rickettsia, Spirochetes, Chlamydia bacteria. But this drug has almost no effect on gram-negative aerobic bacteria. This drug mechanism binds reversibly to the 50S ribosomal subunit of susceptible bacteria and inhibits protein synthesis. When applied to the skin, erythromycin is not significantly absorbed. Erythromycin also has an effect on the inflammatory response, one of the causes of acne. Topical drugs act on the group of bacteria that are concentrated in the hair follicles. Although the mechanism is not very clear.
