Is Ultracel safe to have on face if Dermalive filler was done 15 years ago?

I had Dermalive permenant facial filler 15 + years ago. I am now 50. At the time of having the filler I was very underweight at 6 stone. I am now normal weight at 7 stone. The most my weight goes up is 7.5 stone. However as I put weight on, it shows on my face. I have fairly good skin for my age but have noticed slight laxity especially on the jowl area, hence why I am thinking to have Ultracel treatment. Please advise if it is safe to have Ultracel if I had Dermalive filler 15 + years prior?
