Best Restylane family filler to camouflage dents?

Dear Affectionate9741, 

Thanks for sharing your photo. It is helpful. 

I sub-categorize the hyaluronic acid (HA) gel fillers according to: 

volumizing (filling space), 
projection (tension) and 
lines. 
Restylane provides 3 generations of fillers with different behaviors; according to the length of the molecule and its cross-linking. 

Generation 1: Restylane classic: general volume. Good to great for lips, folds, dents, cheeks, chin, temples, hands...
Generation 2:Restylane Lyft: best projection. Good to push out an area like the cheeks, chin, lateral oral commissure, buccal lip projection...
Generation 3: Restylane Refyne: best for dermal wrinkles / etched lines and Restylane Defyne for folds. This generation reduces the obvious over-fill associated with prior generations and fades nicely into the adjacent tissue providing resistance against re-creasing the line / wrinkle / fold.
Refyne for lip white line and peri-oral wrinkles, crows feet, facial skin lines, forehead furrows and necklace lines.
Defyne for deeper areas of folding (smooth rounded trough): good for folds, dents and lateral oral commissures and vermillion lip. 
Based on your photo, I would say Defyne. Please consult with a Board Certified Plastic Surgeon with lots of experience and skill using minimally invasive injectables. All the best!

Hello and thank you for your question and photo.  I love using Restylane Refyne for finer lines , it won't give you too much volume but just enough for what you're seeking.
