Injection Dermatitis 101
Injection dermatitis shows inflammatory changes around injection sites after repeated injections or irritant exposures commonly seen in clinical practice. Clinically it can mimic acne or folliculitis, but causes and treatments differ, making accurate diagnosis essential. Understanding the distinction guides targeted therapy and avoids unnecessary antibiotics and reduces side effects. Ongoing evaluation ensures therapy remains aligned with the skin’s healing stage.
Laser Therapy Options
Diagnosis relies on history and examination, ruling out rosacea. Laser therapy is not first-line but can improve texture and redness when combined with careful topical care. In Korea, fractional resurfacing and vascular lasers are common choices. Choosing the right device depends on inflammation level and patient downtime.
Fractional CO2 and Er:YAG lasers create micro-injuries that stimulate collagen and smooth texture. Non-ablative 1550 nm and picosecond lasers offer gentler improvements with shorter downtime. Clinicians tailor modalities to redness and texture based on skin type. This combination targets surface and deeper layers for balanced results.
Most plans include 3 to 5 sessions spaced 4 to 6 weeks apart, depending on response. Clinicians monitor for swelling, crusting, and pigment changes, adjusting energy as needed. Adjunctive therapies such as topical retinoids and sun protection support results long-term. Feedback from the skin guides energy adjustments.
Postcare and Skin Rebuild
Post-procedure skincare focuses on barrier repair and sun protection to sustain laser gains. Gentle cleansers, ceramide-rich moisturizers, and fragrance-free formulas aid recovery. Regular sunscreen reduces pigment alterations and flare-ups. Maintenance steps include avoiding harsh exfoliation for several days.
Long-term benefits include increased collagen and improved skin resilience. Laser remodeling promotes smoother texture and more even tone over time. A structured maintenance plan helps preserve gains from laser therapy in injection dermatitis. Maintenance visits help sustain improvements and prevent relapse.
