Prescription muscle-relaxing injections
- Best for: Dynamic horizontal lines visible during movement
- Downtime: Minimal — brief pinpoint redness
- Lasts: Around 3–4 months, varies between individuals
For dynamic forehead lines, prescription injectables that temporarily soften the activity of the frontalis muscle are one of the most extensively studied options in aesthetic medicine. By relaxing the muscle just enough, the skin folds less with each movement, and the lines gradually soften.
Prescription muscle-relaxing injections work by temporarily reducing the activity of specific muscles, so the skin above them stops folding with each movement. The active ingredient is botulinum toxin type A, a purified protein delivered in very small, precisely placed doses. These are prescription-only medicines in the UK, which means they can only be prescribed and administered by a qualified medical prescriber following a face-to-face consultation. Whether this treatment is suitable for you, and what specific product or dose would be used, is something Dr Garara will discuss with you at consultation. It is not suitable for everyone.
In the UK, some botulinum toxin products are licensed specifically for the glabellar (frown line) area between the brows, while licensing for the horizontal lines of the forehead itself varies between products. Where a particular product is not licensed for forehead lines, treating them is an off-licence use:
This use of botulinum toxin is what’s known as “off-licence” — established, lawful practice in qualified medical hands, but not specifically licensed by UK regulators for this particular indication. Dr Garara will explain this fully at consultation, including why he considers it appropriate for your case, and will obtain your informed consent before any treatment.
The forehead is a particularly sensitive area to treat. Over-treating it, or treating the upper forehead without accounting for the brow-depressor muscles below, can lead to a heavy or dropped brow. Dr Garara uses a careful, balanced dosing approach, treating the forehead as one connected system with the brow and frown area, to soften lines while keeping your brow position natural. It is not suitable for everyone — for example, it is not recommended during pregnancy or breastfeeding, or for people with certain neuromuscular conditions — which is why a consultation always comes first.
