Hello, and thank you for sharing your photos and question. Experiencing increased undereye shadowing after a significant weight loss of 25 pounds is very common, especially around the age of 31. When facial volume decreases due to weight loss, the skin and fat pads in the periorbital area can deflate, creating deeper tear troughs and casting shadows that persist even with makeup. As an advanced licensed aesthetician at Laser Skin Solutions – Portland, I frequently consult with patients looking to rejuvenate the delicate undereye area without traditional surgery. Both Platelet-Rich Fibrin (PRF), PRF EZ Gel, and advanced biologics/growth factor injections are excellent, regenerative approaches for this specific concern: PRF and PRF EZ Gel: PRF is derived from your own blood, concentrating platelets, white blood cells, and fibrin. When spun into an albumin-based gel (EZ Gel), it provides an autologous, smooth volume replacement while simultaneously stimulating natural collagen and elastin production. Because it uses your body's own growth factors, it is biocompatible and helps improve skin thickness and quality over time, making it ideal for the thin skin under the eyes. Advanced Biologics & Growth Factors: These treatments focus heavily on cellular repair, tissue regeneration, and improving microcirculation. They help restore dermal thickness and vitality to shadowed, thinning skin. Key Considerations for Your Treatment Plan:Anatomy Matters: Undereye shadowing can be caused by a combination of volume loss (hollows), structural shadowing, and sometimes hyperpigmentation (dark circles). A professional in-person assessment will determine whether regenerative biologics alone or a combination approach is best for you. Gradual, Natural Results: Regenerative treatments rely on your body's biological response. Improvements in skin texture, thickness, and shadow reduction typically develop gradually over several weeks to months. I recommend scheduling a consultation with a qualified, experienced provider who specializes in regenerative aesthetics to evaluate your unique periorbital anatomy and discuss a personalized treatment plan.
