Best Alternative Treatments for Under Eye Wrinkles?

Ladies and gentlemen, I'm a 38-year old German man with severe under eye wrinkles, espec. when smiling. Wrinkles started to appear with strong weight loss (75/63 kg) with the result that my face looked older. Treatment of other facial parts with Botox was fine, but my doctor refused to insert more than 1.5 u of Botox under each eye. Which good surgical or non-surgical options do you recommend, includ. make-up or camouflage? Thank you
