Anti-Wrinkle Injections: Which Lines They Treat Best, and When You Need Something Else

Anti-wrinkle injections are one of the most requested treatments at our Tropicana Avenue clinic, and also one of the most misunderstood. Many people arrive expecting a single injection to smooth every line on the face. In reality, anti-wrinkle injections work brilliantly on some lines, only partly on others, and not at all on a few. Knowing which is which saves you time, money and disappointment.

This guide explains how our LCP-certified doctors decide whether anti-wrinkle injections are right for your lines, and when a filler, skin booster or lifting treatment will do a better job.

How anti-wrinkle injections actually work

Anti-wrinkle injections (at Dr Jane Clinic we use Botox® by Allergan) relax the specific muscles that crease the skin when you frown, squint or raise your brows. When the muscle moves less, the skin above it folds less, and the line softens.

That mechanism is the key to everything that follows. Anti-wrinkle injections treat lines caused by muscle movement. They do not add volume, tighten loose skin or rebuild collagen. So the first question a good doctor asks is not "where are your wrinkles?" but "what is causing them?"

Dynamic lines vs static lines: the test you can do at home

Look in the mirror and make a few expressions, then relax your face completely.

• Dynamic lines appear only when you move: forehead lines when you raise your brows, the "11s" between the brows when you frown, crow's feet when you smile. These respond best to anti-wrinkle injections.

• Static lines are still visible when your face is at rest. They are usually etched-in dynamic lines, loss of volume, or skin that has become thinner and less elastic over time.

Static lines often improve partly with anti-wrinkle injections, because the muscle stops deepening the crease, but they rarely disappear fully on injections alone. This is where combination treatment comes in.

Lines that respond well to anti-wrinkle injections

Our doctors commonly use anti-wrinkle injections for:

• Forehead lines: horizontal lines from raising the eyebrows

• Frown lines (the "11s"): vertical lines between the brows

• Crow's feet: fine lines fanning out from the corners of the eyes

• Chin dimpling: the "orange peel" texture some people get on the chin

• Neck bands: vertical cords that show when the neck muscles tense

Anti-wrinkle injections are also used beyond wrinkles, for example to slim a square jaw caused by strong chewing muscles.

Lines that need something else

Smile lines (nasolabial folds)

The lines running from the nose to the corners of the mouth are mostly about volume and support, not muscle movement. Relaxing the muscles here can affect your smile, so these lines are usually better treated with nasolabial fold filler or by restoring support in the mid-face.

Deep static lines and hollows

When a line is visible at rest because the area has lost volume, a dermal filler can lift the crease from beneath. Our doctors use hyaluronic acid fillers such as Juvederm, which can be dissolved if ever needed, and Radiesse, a collagen-stimulating filler that suits some patients looking for gradual structural support.

Fine crepey lines and dull, thin skin

Fine lines across the cheeks or under the eyes that come from dehydration and thinning skin are not caused by one muscle, so anti-wrinkle injections cannot target them. Skin boosters such as Profhilo, Skinvive or PDRN improve hydration and skin quality instead. If you are deciding between these, our comparison of Profhilo vs Skinvive vs PDRN explains the differences.

Sagging and jowls

If lines are mainly caused by skin that has dropped, such as jowls or heavy lower-face folds, relaxing muscles will not lift them. Collagen-stimulating lifting treatments such as HIFU or Ultherapy are designed for this.

Why many patients do best with a combination

Most faces in their late 30s and beyond have a mix of dynamic lines, some volume loss and some change in skin quality. A sensible plan often looks like this:

• Anti-wrinkle injections to relax the muscles that keep folding the skin

• A small amount of filler where volume loss is deepening a line

• Skin boosters to improve texture and glow over a course of sessions

Combination plans do not mean more is better. Our doctors would rather do less, review you, and build up gradually than overcorrect. The goal is that you look rested, not "done".

What to expect on the day and afterwards

• Consultation first: your doctor assesses your lines at rest and in motion, and asks about your medical history.

• The injections: usually around 10 to 15 minutes. Numbing cream may be applied for comfort.

• Downtime: no downtime is needed, and most people return to daily activities straight away. Small marks or mild redness at injection points usually settle quickly.

• When you see results: improvement typically appears within 3 to 7 days.

• How long it lasts: generally 3 to 6 months, varying from person to person, after which treatment can be repeated if you wish.

Realistic expectations

Anti-wrinkle injections are very effective for the right lines, but they have limits. They soften rather than erase deep static creases, they wear off over months, and they cannot fix sagging or volume loss. Results also depend on your skin, your muscle strength and your lifestyle, especially sun exposure and smoking. A good consultation should tell you honestly what injections will and will not achieve for your face, and sometimes that means recommending a different treatment altogether.

Frequently asked questions

Will anti-wrinkle injections make me look frozen?

Not when they are dosed carefully. Our doctors aim to soften lines while keeping natural expression. Starting with a conservative dose and reviewing you afterwards helps avoid a stiff look.

Can anti-wrinkle injections remove smile lines?

Usually not. Smile lines (nasolabial folds) are mainly caused by volume loss and facial structure rather than a single muscle, so filler or mid-face support is often the better choice.

At what age should I start anti-wrinkle injections?

There is no set age. What matters is whether you have dynamic lines that bother you. Some people start when lines first begin to stay visible at rest; others never need them. Your doctor can advise you at consultation.
