Preface: Tretinoin, a topical retinoid derived from vitamin A, has been a cornerstone in dermatological practice for decades. Its versatile operational mechanism ensures effectiveness in managing a variety of skin disorders, especially acne vulgaris and photoaging. This report reviews two cases, one involving moderate acne vulgaris and the other with sun-damaged skin, emphasizing tretinoin’s effectiveness, possible adverse effects, and the value of patient instruction and handling. Example 1: Moderate Acne Vulgaris A 24-year-old woman appeared with moderate acne vulgaris identified by inflammatory papules and pustules chiefly on the face, especially the cheeks and forehead. Her health history was uneventful, and she negated any substantial family history of acne. She had tested OTC benzoyl peroxide and salicylic acid items with slight betterment. After a comprehensive review, a diagnosis of moderate acne vulgaris was determined. Regimen was commenced with a 0.025% tretinoin cream put on nightly after washing and entirely drying the skin. The patient was guided to initiate with application every second night for the first week to minimize irritation, steadily enhancing the oftenness as tolerated. She was further recommended to apply a wide-spectrum sunscreen with SPF 30 or more every day, including cloudy days, to guard against sun sensitivity, a typical side effect of tretinoin. During the first month of treatment, the patient experienced mild erythema, dryness, and scaling, which were managed with the use of a gentle, fragrance-free moisturizer applied twice daily. These starting unwanted effects steadily lessened. By the third month, a significant reduction in inflammatory lesions was observed, with a notable improvement in overall skin texture and tone. At the six-month point, the patient’s acne had substantially cleared, with just sporadic non-inflammatory comedones left. She reported elevated satisfaction with the regimen results. Maintenance regimen with tretinoin was proceeded at a diminished frequency to prevent return. Example 2: Photodamaged Skin A 55-year-old female presented with concerns about visible signs of photoaging, including wrinkles, hyperpigmentation, and rough skin texture. She had a history of significant sun exposure throughout her life and reported infrequent sunscreen use. Physical inspection uncovered fine lines and wrinkles near the eyes and mouth, coupled with varied pigmentation and a rugged texture to the skin. Regimen was commenced with a 0.05% tretinoin cream put on nightly after washing and moisturizing. The individual was recommended to begin with use every alternate night for the initial week and slowly raise the frequency as endured. The necessity of consistent sunscreen employment was emphasized, and she was provided with a high SPF broad-spectrum sun shield. The subject experienced more evident initial drawbacks versus the acne patient, such as significant dryness, scaling, and redness. These were managed with elevated moisturizer employment and momentary diminishment in tretinoin application pace. After several weeks, the side effects lessened, and improvements in skin texture and tone became apparent. By the six-month point, a notable decrease in fine lines and wrinkles was noted, together with enhanced skin color and feel. Hyperpigmentation exhibited progressive betterment, although total resolution was not attained. The subject was happy with the total improvement in her skin’s aspect. Ongoing care with tretinoin was maintained to preserve the obtained outcomes. Analysis: These two examples demonstrate the adaptability of tretinoin in addressing various skin issues. Its effectiveness in acne stems from its ability to normalize keratinization, reducing comedone formation and preventing inflammation. In photoaging, tretinoin stimulates collagen production, improves skin elasticity, and reduces hyperpigmentation. Nevertheless, tretinoin‘s potency comes with likely side effects, chiefly associated with skin irritation. These consist of erythema, dryness, flaking, peeling, and increased sun vulnerability. The harshness of these drawbacks varies depending on the tretinoin dose, oftenness of application, and individual patient aspects. Careful patient selection, appropriate initial dosing, and gradual titration are crucial to minimize irritation and ensure treatment adherence. Patient education regarding the expected side effects, the importance of sunscreen use, and appropriate skin care regimens is paramount for successful treatment. Wrapping Up: Tretinoin persists as a beneficial therapy for acne vulgaris and sun-damaged skin. Its efficiency is well-founded, but its use calls for careful individual selection, adequate dosage, and attentive patient education to manage potential drawbacks. This case study highlights the importance of individualized treatment plans and the need for ongoing monitoring to ensure optimal outcomes and patient satisfaction. Additional studies are in progress to investigate new compositions and mixes of tretinoin with other topical remedies to improve effectiveness and reduce adverse effects.
