When time begins to count backwards and its signs become visible on the face and body, after the age of 30 we start to think about wrinkles, which appear more dynamically.
By the age of 40, the first signs of skin laxity also become visible, which gradually intensify. Another battle begins: how do we deal with this too?
At this stage, we often worry more about our appearance and wonder which aesthetic approach is right to help us ‘pause’ time for longer while achieving longer-lasting results.
It is a fact that treatment options for wrinkles and skin laxity vary, as they are not the same for everyone. Botulinum toxin type A (Btx) and hyaluronic acid fillers are two long-lasting treatments that ensure smoother facial wrinkles, improved skin quality, and a fresh, youthful look.
Both treatments are highly effective in reducing wrinkles, but they are not suited for everyone in the same way.
So, what are the key differences between Btx and hyaluronic acid fillers to help you decide which suits you best?
Btx vs Fillers
Both are aesthetic treatments administered via injection, performed only in a certified plastic surgeon’s office. They are minimally invasive procedures without surgery. That is where the similarities end.
Btx works as a muscle relaxant. It contains botulinum toxin type A, a weakened neurotoxin. Initially used for neurological disorders causing muscle weakness, Btx has since become a cornerstone in aesthetic plastic surgery.
It can also treat migraines and other medical conditions. In aesthetics, Btx minimizes dynamic wrinkles that deepen over time due to facial expressions, such as crow’s feet, frown lines, and forehead lines.
Fillers, on the other hand, are designed to restore lost volume in tissues due to aging. They are widely used to smooth nasolabial folds, enhance lips and cheekbones, and restore firmness to the face. Fillers can also be applied to the hands or even to prevent scar formation.
The most common filler is hyaluronic acid, which also stimulates collagen production. By adding volume in targeted areas, fillers restore youthful contours and improve skin texture.
Which is more effective?
The answer: whichever your face needs! For deep expression lines, Btx is recommended. For areas without strong muscle contraction but with volume loss, fillers work best. Often, a combination of both provides the most natural results.
Btx reduces muscle activity, preventing wrinkles from deepening, while fillers plump and smooth the skin in static areas.
How long do results last?
Results vary. Some fillers last 6 months, others up to 2 years. Btx is not permanent: its effect lasts about 4–6 months, after which retreatment is necessary to maintain results.
At what age should I start Btx & Fillers?
Studies suggest that starting Btx early can help prevent the formation of new wrinkles. Many surgeons recommend beginning at the first sign of lines—often around the age of 30.
Both Btx and fillers are excellent options for different needs: Btx prevents and smooths wrinkles, while fillers add volume to areas like the lips, cheeks, jawline, and nose.
