Hello! Congratulations on your incredible weight loss and maintenance—it’s a major achievement! At 38, it’s understandable to notice some skin laxity, especially in the neck area, after such a significant transformation. The skin's ability to retract after weight loss varies based on genetics, age, collagen quality, and how quickly the weight was lost. Neck straining during heavy lifting can emphasize or temporarily worsen the appearance of looseness but likely didn’t cause the laxity itself.
