What's the next step after LED + microcurrent for forehead line?

Hi guys! I’m in my late 30's and my main concern is a single forehead line.

I’m currently using a red light therapy mask, microcurrent, and retinol (planning to switch to retinal soon), and I’m consistent with sunscreen.

I’m wondering what would be the most effective next step—would something like RF or silicone patches make a noticeable difference, or should I just stick with my current routine?

Would really appreciate hearing what worked for others!
