Can filler give you a baby face and chubby cheeks?

fillers and sculptra can be used to contour the face and give it more volume yes.

at home peels like cosmelan, enlighten and aerify along with dermarolling (MTS roller with anteage MD ampules weekly, see linkt) should be started now to prevent further aging.

For facial rejuvenation, I would suggest a combination approach of
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)

Best, Dr. Emer.

Hello and thanks for your question. A face to face consult is always preferred however from what you have described yes fillers can be used to help add volume to areas you have lost it from due to ageing. Always seek a qualified and experience practitioner, best wishes
