This article is the starting point.
If you’re at the beginning and unsure what separates Botox from filler, or you’ve heard names like Sculptra, PDRN and exosomes and lost track, or every clinic seems to recommend something different — this will lay out the whole picture.
We’ll go through each treatment: what it does, who it suits, how long it lasts, and what it costs. Where you want more, each section links to a dedicated article covering that topic in full.
You don’t need to read everything. Read the section that applies to you — or just take the table below.
The whole map in one table
| Treatment | What it does | Treats | Results appear | Lasts | Reversible? |
|---|---|---|---|---|---|
| Botulinum toxin | Relaxes muscle | Movement lines | 3 – 7 days | 3 – 6 months | Wears off |
| Filler | Fills and lifts | Volume loss | Immediately | 6 – 18 months | Yes, with enzyme |
| Skin boosters | Hydrate from within | Dryness, dullness | 1 – 3 weeks | 6 – 12 months | No (but fades) |
| Sculptra | Stimulates collagen | Generalised laxity | 6 – 12 weeks | Up to 2 years | No |
| Radiesse | Immediate support + collagen | Jawline, neck | Immediately, then improves | 12 – 18 months | No |
| PDRN / Rejuran | Stimulates skin repair | Damage, redness | 4 – 6 weeks | 6 – 12 months | No |
| Exosomes | Cell signalling | Radiance, inflammation | Weeks | Variable | No |
| Profhilo | Deep hydration + mild firming | Thin skin | 3 – 4 weeks | 6 – 9 months | Yes (HA) |
| Skinvive | Single-session hydration | Roughness, dullness | 1 – 2 weeks | ~6 months | Yes (HA) |
| Hybrid fillers | Fill + stimulate together | Volume and skin quality | Immediately, then improves | 9 – 12 months | Partially only |
| Mesotherapy | Superficial nourishment | Mild dullness | 2 – 4 weeks | 3 – 6 months | No |
How to read that table
The column most people skip is the last one: reversible or not.
That isn’t a technical footnote. It’s the difference between a treatment you can remove in a day if you dislike it, and one you’ll live with for months. If this is your first time, start from that column before any other.
Family one: muscle relaxants
Botulinum toxin
Works on muscle, not skin. Injected, the muscle relaxes, so the skin above it stops creasing with expression.
Works for: forehead lines, frown lines between the brows, crow’s feet, gummy smile, a subtle brow lift, and vertical neck bands.
Doesn’t work for: static lines already visible when your face is at rest, volume loss, or laxity. If the line is there when you’re making no expression, toxin alone isn’t enough — it needs combining with something else.
Uses that aren’t purely cosmetic
Part of this is more medical than aesthetic, and most people don’t know it:
Masseter treatment — slims the jaw angle, and also relieves teeth grinding that causes morning headaches and jaw joint pain.
Excessive sweating — underarms and palms, an established and effective use.
📄 Full detail: Masseter botox: jaw slimming and teeth-grinding relief
Preventative toxin — worth it or not?
The idea is reducing the frequency of the contraction that etches a line, before that line becomes static.
My honest view: reasonable in selected cases, not necessary for everyone. If no line shows when your face is at rest, you can wait.
Family two: volumising fillers
Filler
A hyaluronic acid gel injected to fill a space and add volume. The result is visible while you’re still in the chair.
Works for: lips, hollow cheeks, chin and jaw definition, nasolabial folds, and under-eye hollows in suitable cases.
A point rarely made: filler is not the answer to every dark circle. Under-eye darkness has four different causes — pigmentation, visible vessels, a bony hollow, and thin skin. Filler solves one of them. With the others it can make things look worse.
📄 Full detail: Skin boosters under the eyes — do they really fix dark circles?
Hybrid fillers
A newer generation combining immediate hydration with long-term stimulation in one product — such as Rich PL (hyaluronic acid + polylactic acid) and Sfera.
There’s a trade-off you should know: the hyaluronic portion dissolves, the stimulating portion doesn’t. So correction is partial.
📄 Full detail: Rich PL and hybrid fillers · Sfera: the multi-component hybrid
Family three: collagen biostimulators
This family works on completely different logic: they don’t fill, they build. The material prompts your body to produce collagen, then disappears — and the collagen remains.
So what you see months later isn’t the product. It’s your own tissue. Which is why it looks so natural.
Sculptra
Poly-L-lactic acid. The strongest at building long-term volume, and the slowest to show. Excels with generalised laxity, cheeks and hollow temples.
Important: not reversible, and never used in lips.
📄 Full detail: Sculptra vs filler · Sculptra aftercare and the massage protocol
Radiesse (calcium injections)
Calcium hydroxylapatite. The only one combining immediate support with collagen stimulation. Excels along the jawline, the neck, and in hand rejuvenation.
It also has a little-known hyperdilute use: it becomes a broad-area collagen stimulator improving skin quality without adding volume.

📄 The whole family compared: Collagen biostimulators — the complete guide
Family four: skin renewal and hydration
These don’t change how you look. They improve the quality of the skin itself — texture, tone, pores, hydration.
Skin boosters
Light hyaluronic acid injected at many points to hydrate from within and stimulate collagen. By far the most popular in Egypt — and the most misunderstood, because people judge the result after one session when the protocol is three.
📄 Full detail: How long do skin boosters take to work?
PDRN and Rejuran
Fragments of salmon-derived DNA that signal fibroblasts to repair the skin and reduce inflammation. Best for sun-damaged, sensitive and reddened skin.
Rejuran isn’t something different — it’s a brand name for a PDRN-based product.
📄 Full detail: PDRN before and after · Rejuran and salmon-DNA injections
Exosomes
Vesicles carrying signals between cells. A promising direction, but the evidence is newer and thinner than the rest, and regulatory status varies by country. That should be said plainly before anyone pays for it.
📄 Full detail: Exosomes for skin
Profhilo and Skinvive
Both for deep hydration. Profhilo is high-concentration, non-cross-linked hyaluronic acid that spreads under the skin and gives a mild firming effect. Skinvive’s advantage is being a single session rather than a multi-session protocol.
📄 Full detail: Profhilo · Skinvive
Mesotherapy
A vitamin and mineral cocktail injected superficially. Cheaper and quicker, but shorter-lived and needing more sessions. Useful as general improvement, not as treatment for a specific problem.
Beyond injectables: what else exists
For the picture to be complete and honest, there are non-injectable procedures competing for the same problems:
HIFU and ultrasound tightening — heat-based lifting, suiting mild to moderate laxity. An alternative or complement to biostimulators.
Thread lifts — immediate mechanical lift plus collagen stimulation. Clearer lifting than injectables, but longer downtime.
Microneedling and fractional laser — for skin quality, scarring and pores. Frequently combined with PDRN and exosomes.
We won’t detail them here, but it matters that you know injectables aren’t the only option — and that a doctor offering only injectables without mentioning these alternatives is offering what they have, not what suits you.
So how do you choose?
The only rule you need: start from the problem, not the name.
| What’s bothering you | Best-suited treatment |
|---|---|
| A line when I frown | Botulinum toxin |
| A line that’s there at rest | Toxin + filler or stimulation |
| Hollow cheeks | Filler or Sculptra |
| Dull, dry skin | Skin booster |
| Enlarged pores, sun damage | PDRN |
| Red, sensitive skin | PDRN |
| General sagging | Sculptra |
| Blurred jawline | Radiesse or filler |
| Loose neck | Hyperdilute Radiesse or HIFU |
| Hands look older than I am | Radiesse |
| Thin lips | Filler |
| Dark circles from a hollow | Under-eye filler |
| Dark circles from pigment | Not filler — different assessment |
| Fine lines under the eyes | Skin booster or PDRN |
| Wide jaw from muscle | Masseter toxin |
| Thin skin that’s lost bounce | Profhilo |
| Preventing laxity early | Low-dose Sculptra or PDRN |
📄 The detailed comparison: Botox vs filler vs skin booster vs Sculptra vs PDRN
Dr. Rehab Zakaria’s advice: “I don’t ask a patient what she wants done — I ask what’s bothering her. That difference is what stops someone paying for a treatment that was never going to give her the result she had in mind. Plenty walk in asking for filler and walk out with a completely different plan, and they’re happier for it.”
A roadmap by age
A guide, not a rule — genetics and lifestyle matter more than the number:
| Stage | Focus | Possible treatments |
|---|---|---|
| Late twenties | Protection and prevention | Sun protection, topicals, preventative toxin if indicated |
| Early thirties | Skin quality | Skin booster or PDRN, light toxin |
| Late thirties | Quality + preserving structure | Regular hydration, toxin, assess early volume loss |
| Forties | Replacement and correction | Biostimulators, targeted filler, combined plan |
| Fifties and beyond | Structural support + quality | Sculptra/Radiesse, considered filler, tightening technologies |

Combining treatments — and the right order
Most real plans aren’t a single treatment. And sequence matters:
Toxin + skin booster — the most popular pairing by far. Toxin for movement, booster for skin quality.
Sculptra then filler — start with Sculptra, wait 3–4 months for the result to settle, then reassess whether definition is still needed. Many patients find they need far less filler than expected.
PDRN + skin booster — both target skin quality through different mechanisms.
Microneedling then PDRN or exosomes — the first opens channels, the second penetrates.
The general rule on sequence: foundation before detail. Build overall support first, then do precise definition.
What actually happens in a session?
People are anxious about the unknown, so let’s remove it. The steps are similar across most treatments:
Assessment — questions about medical history, medications and allergies, plus an actual examination. If this stage is skipped, that’s a warning sign, not time saved.
Photographs — before and after in consistent lighting. Important so you can compare honestly later.
Cleansing and numbing — topical anaesthetic for 15 to 30 minutes depending on the area.
Injection — from 10 minutes (toxin) to 40 minutes (a broad protocol).
Instructions — the part rushed at the end and then forgotten. Ask for them in writing.
Timing: when will you see results?
The biggest cause of disappointment isn’t the product — it’s the wrong expectation:
| Family | First sensation | The real result |
|---|---|---|
| Botulinum toxin | 3 – 7 days | 2 weeks |
| Filler | Immediately | After swelling settles (2 weeks) |
| Hydration (booster/Profhilo) | 1 – 2 weeks | A month after the protocol |
| Repair (PDRN) | 4 – 6 weeks | After 3 – 4 sessions |
| Collagen biostimulators | None | 3 – 6 months |
If anyone promises an immediate result from Sculptra, they either don’t understand it or they’re selling.
Aftercare essentials for any injectable
Details differ, but there are constants:
First 24 hours: don’t touch or massage the area (unless your doctor prescribed specific massage, as with Sculptra), no makeup for 12 hours, don’t sleep face-down.
First 48 hours: no intense exercise, saunas or hot baths.
From day two: daily sun protection. This isn’t routine advice — UV breaks down the collagen you paid for.
Small bumps at injection points and mild redness are expected with most hydration and stimulation injectables, and settle within one to three days.
Pricing: how to read the number properly
Published Egyptian market ranges for 2026, approximately:
| Treatment | Range (EGP) | Unit |
|---|---|---|
| Botulinum toxin | 1,500 – 6,000 | Per area |
| Filler | From 6,000 | Per syringe (1 ml) |
| Skin booster | 3,500 – 6,000 | Per session |
| Sculptra / Radiesse | After assessment | Per plan |
The most important advice: don’t compare session prices.
Skin boosters cost less per session but the protocol is three. Filler costs more once but lasts longer. The fair comparison is the cost of reaching a result and maintaining it for a year.

Safety: what to know before any injection
Most side effects are mild and temporary — redness, swelling, bumps, bruising — settling within one to three days.
Serious complications are very rare but real, the most severe being vascular occlusion with filler.
Signs requiring immediate contact with your doctor:
Severe or increasing pain · skin turning pale, white or blue · redness increasing after day three · warmth in the area · any change in vision · sudden obvious asymmetry.
Who isn’t a candidate: pregnancy and breastfeeding, active infection or inflammation at the injection site, unstable autoimmune conditions, clotting disorders, and known product allergy.

Myths worth correcting
“Filler leaves hollows when it wears off.” No. It breaks down gradually and tissues return to their natural state for your age.
“Botox accumulates in the body.” No. It breaks down locally and is cleared.
“If you stop, you’ll look worse.” No. You return to the natural state you’d have reached anyway.
“Injectables enlarge your pores.” No basis for this.
“It’s natural, so there’s no risk.” A substance existing in the body doesn’t make injecting it risk-free. The risk is in the procedure, not only the product.
“Skin boosters make your face puffy.” No — they aren’t volumising. Any swelling is temporary and settles in two days.
How to choose a clinic
Ask these before any injection, and leave if the answers are vague:
- What is the product name and manufacturer?
- Exactly how many millilitres or units will you inject?
- Will the packaging be opened in front of me?
- Does the price include follow-up if adjustment is needed?
- If a complication occurs, what’s the plan?
- For filler: do you keep hyaluronidase on site?
That sixth question isn’t optional. A clinic injecting filler without dissolving enzyme available is an unjustified risk.
Warning signs: a price quoted in the first two minutes · pressure to book today · “last day” offers · no mention of risk · the injector isn’t a doctor · no questions about your medical history.

For Gulf visitors and expatriate residents
A significant share of our patients travel from Saudi Arabia, the UAE and Kuwait, or are expatriates living in Cairo. Practical points:
Multi-session protocols (skin boosters, PDRN, Sculptra) need more than one visit. For a short trip we can do the first session and either complete it on a later visit or arrange video follow-up.
Single-session treatments (toxin, filler, Skinvive, Radiesse) suit short visits better.
Leave time before travelling — at least two weeks after filler for bruising, and avoid flying in the first 24 hours after injection.
For events — plan a month ahead for hydration treatments, two months for biostimulators.
Terminology varies: what Egypt writes as سكلبترا the Gulf writes as سكالبترا, and محفزات الكولاجين and إبر النضارة are more common Gulf phrasings than “skin booster”. They all refer to the treatments described above.
A quick glossary
Hyaluronic acid — a compound naturally present in skin that binds water. The basis of filler and skin boosters.
Cross-linked — chemical treatment that makes hyaluronic acid cohesive so it stays put and creates volume. Non-cross-linked spreads and hydrates instead.
Fibroblasts — the cells that produce collagen and elastin. Every biostimulator works by signalling them.
Hyaluronidase — the enzyme that dissolves hyaluronic acid filler. The safety net.
Nodules — small clusters under the skin, the characteristic risk of biostimulators, reduced by correct dilution and massage.
Vascular occlusion — product entering a blood vessel. Very rare but an emergency.
PLLA — poly-L-lactic acid, the substance in Sculptra.
CaHA — calcium hydroxylapatite, the substance in Radiesse.
Quick answers
I’m in my thirties, where do I start? Usually a skin booster or low-dose toxin. You don’t have to start with filler.
If I stop, will I look worse? No. You return gradually to your natural state for your age.
Are injectables addictive? The product isn’t. Repeated overtreatment without assessment is the problem.
Can I have two treatments the same day? Yes, in many cases.
Does it hurt? With numbing cream, a light prickling for most treatments.
Can I have treatment while fasting? Injectables aren’t nutritive, but we advise scheduling after breaking the fast for medical reasons — dehydration increases dizziness and bruising.

The bottom line
Aesthetic injectables aren’t a product list where you pick the most expensive or the most famous. They’re four families solving four different problems: toxin for movement, filler for volume, biostimulators for laxity, renewal injectables for skin quality.
If you take one thing from this article, take this: the right treatment is the one that solves your problem — not the one you saw on Instagram, and not the one your friend had.
And one last thing: the doctor who tells you “this won’t help you” is doing you a bigger service than the one who agrees to every request.
