A Hello, I completely understand your concern with your undereyes, especially as a male who isn't accustomed to wearing makeup and having to use concealer. I can see how it might help a bit but doesn't fully cover everything to your satisfaction.
Thank you for sharing your photos; they are very informative and can help other patients with similar concerns. The undereye area can present several issues such as darkening, hyperpigmentation, hollowness, skin laxity, and/or lesions like syringomas or xanthelasmas. In your case, since you exhibit all these conditions, a multimodal approach with progressive results will offer the most beneficial long-term outcomes.
I recommend starting with a thorough in-person analysis and medical consultation. Prioritizing the removal of syringomas with a CO2 laser is essential, and improving the overall area with fractional CO2 laser can be done in the same session, along with IPL and vascular laser treatments for the pigmentation. Subsequent sessions may be necessary to continue addressing the pigmentation with IPL and vascular lasers.
Fillers might also be needed, but it is essential to approach this comprehensively, improving the cheeks first, then addressing the lid-cheek junction with fillers. These fillers tend to last longer than the product specifications suggest, especially since regenerative procedures are applied first. Concerning your question about the need for dissolving fillers, it's unlikely to be necessary, but if it is, the skin should not appear worse than before, especially with the prior regenerative procedures.
An alternative to CO2 resurfacing could be using SylfirmX pulsed wave to improve everything but the syringomas, which need to be removed with a CO2 laser.
I hope this explanation helps you make more informed decisions regarding your concerns.
