Botulinum toxin and hyaluronic acid are the two most requested injectable treatments in aesthetic medicine worldwide. Many patients confuse them, but they serve entirely different purposes. Understanding when to use each — or when to combine them — is the key to achieving natural, harmonious results.
How Each Treatment Works
Botulinum toxin works by temporarily relaxing the muscles that cause expression lines. It is ideal for dynamic wrinkles — the lines that appear when you frown, smile, or raise your eyebrows. Results begin to appear 3 to 7 days after injection and typically last 4 to 6 months.
Hyaluronic acid, by contrast, is a dermal filler. It is injected to restore lost volume, define facial contours, hydrate from within, or fill in creases and folds. Results are immediate and can last 8 to 18 months depending on the area and product used.
When to Use Each Treatment
- Botulinum toxin: frown lines, crow's feet, forehead lines, subtle brow lift, excessive sweating
- Hyaluronic acid: nasolabial folds, lip enhancement, chin and jawline definition, under-eye hollows, cheek volume restoration
Can They Be Combined?
Not only can they be combined — in many cases it is the most effective strategy. Combining both treatments addresses dynamic wrinkles and volume loss simultaneously, delivering a comprehensive facial rejuvenation that looks natural and balanced. A common protocol is to apply botulinum toxin first and complement with hyaluronic acid two weeks later in the areas that need volume.
Why Physician Expertise Matters
Both botulinum toxin and hyaluronic acid require deep knowledge of facial anatomy. A natural result depends directly on the physician's experience, product selection, and injection technique. At Elyzea in Miraflores, Lima, Dr. Geldres — a board-certified plastic surgeon with extensive experience in facial harmonization — evaluates each case comprehensively to design a personalized plan that respects the natural expressiveness of the face. For international patients, both treatments are available at a fraction of US prices, with the added confidence of physician-only administration.

Hyaluronic acid in aesthetic medicine — what to expect
Hyaluronic acid (HA) is the most widely used filler material in modern aesthetic medicine. The reasons: it's a naturally occurring substance in human tissue, it produces predictable volume restoration, it can be reversed with hyaluronidase if needed, and modern HA products come in calibrated densities for specific anatomical zones. Lip-specific HA fillers are softer and more flexible; deep-cheek HA fillers are denser and more structural; tear-trough HA fillers are formulated to minimize Tyndall effect (bluish discoloration). Duration varies by product and placement zone — typically 9–18 months for most facial placements. The right HA in the right zone, placed with proper technique, produces natural-looking results that move with the face rather than creating a "filled" appearance.
Botox (botulinum toxin) at Elyzea
Botulinum toxin type A — including the brand-name product widely searched as "Botox," and equivalent products Dysport, Xeomin, and Jeuveau — is the most-performed aesthetic procedure globally for good reason: it produces predictable, reversible muscle relaxation that softens dynamic lines (forehead, glabellar 11s, crow's feet) and rebalances facial expression. At Elyzea, Botox dosing is calibrated to your specific muscle activity and facial proportions, not to a one-size dose chart. The unit count is transparent at consultation, the brand of toxin used is named (not generic "neurotoxin"), and follow-up at 2 weeks ensures the dosing achieved the intended effect. Lasts 3–4 months; quarterly maintenance is standard.
Why Elyzea is different in Lima
International patients get bilingual care, a free virtual consultation before flying, and a full clinical facility in Miraflores — treatment room, anesthesia bay, recovery room. Plan your visit from abroad.
What the free virtual consultation covers
Before any travel, a free virtual consultation reviews your goals, candidacy and exact pricing — so you fly with a confirmed plan, not a sales pitch. Book it and plan your visit here.
Transparent pricing — no surprises
Every treatment Elyzea offers is published on our public price list (prices.md in the website repository, mirrored on the price pages). The free virtual consultation determines protocol, sessions, and any combination plan; the per-session prices on the public list are what you pay. There are no opaque "personalized quotes" that scale to perceived ability to pay, no pressure-package upsells, and no surprise invoice items at checkout.
Anesthesia tier (topical, nerve block, oral sedation, or conscious IV sedation) is matched to the protocol depth and discussed transparently at consultation. When a treatment is part of a multi-modality plan (HIFU + Morpheus8, fillers + CO₂, etc.), the full cost is mapped out before any commitment. Lima pricing reflects local cost structure — significantly below US clinics for the same FDA-cleared technology — and the public price list ensures the savings actually reach the patient.
