Praise an old man for his good skin care.
Good skin care for the elderly is mainly due to years of healthy accumulation and healthy eating habits. It can be said that the key to staying young lies not only in maintenance, but also in good health. So you can praise the elderly for their good skin care, but more importantly, praise their living habits and health preservation methods, and praise them for knowing how to cherish life and pursue health. This will be more appropriate and touching.
