Nonsurgical Facial Rejuvenation

The increasing demand for minimally invasive facial rejuvenation has expanded the role of nonsurgical aesthetic procedures in plastic surgery. These treatments offer meaningful improvement in skin quality, texture, dyschromia, and photoaging while avoiding the morbidity and recovery associated with operative intervention. However, safe and effective treatment selection requires an understanding of skin biology, facial aesthetic principles, phototype, baseline barrier function, and the severity of photoaging. This review presents a practical framework for nonsurgical facial rejuvenation centered on 3 core variables: Fitzpatrick skin type, skin barrier status, and photoaging severity. Foundational concepts, including facial thirds and fifths, stratum corneum physiology, transepidermal water loss, acidic skin pH, and the pathophysiology of ultraviolet-induced photoaging, are reviewed to establish the clinical context for treatment planning. Topical skin care and cosmeceuticals, including sunscreen, antioxidants, retinoids, and barrier-supportive regimens, are discussed as baseline interventions that optimize skin health and improve procedural tolerability. Office-based resurfacing modalities are then reviewed, including chemical peels, microneedling with or without platelet-rich plasma, dermabrasion, microdermabrasion, and laser resurfacing. For each modality, mechanisms of action, common indications, expected recovery, complications, contraindications, and peri-procedural considerations are summarized. Chemical peels provide depth-dependent exfoliation and dermal remodeling but require careful agent selection and counseling regarding pigmentary risk, particularly in higher Fitzpatrick phototypes. Microneedling offers dermal collagen induction while largely preserving the epidermis, making it a useful option across skin types. Platelet-rich plasma may serve as an adjunct to enhance tissue repair and collagen remodeling, though outcomes are influenced by preparation variability. Dermabrasion and microdermabrasion provide mechanical resurfacing at different depths, whereas ablative and non-ablative laser technologies allow adjustable thermal injury for rhytids, scars, dyschromia, and textural irregularities. Overall, nonsurgical facial rejuvenation is best approached as a staged and individualized process rather than a single intervention. Treatment intensity should be matched to patient goals, phototype, baseline skin condition, photoaging severity, and tolerance for downtime. Careful skin preparation, strict photoprotection, appropriate procedural selection, and post-procedure wound care are essential to optimizing outcomes and minimizing complications.
