Hyaluronic acid, Botox¨ or collagen: which jab should you choose?
So what's the deal with these injections that are as a famous as their celebrity endorsers? From collagen injections to hyaluronic acid fillers, here's a closer look at wrinkle-zapping jabs.
They took the cosmetic world by storm during the 90's but have since decreased in popularity. Their main benefit is that they last a long time. Collagen is a connective tissue found in the dermis. It forms part of our skin's inner scaffolding, keeping it firm and toned. However, when it's injected it doesn't interact with our cells in the same manner as naturally produced collagen - it simply densifies skin tissue. What's more the collagen injected is usually sourced from animals, meaning there's a higher risk of allergic and inflammatory reactions alongside a compromised immune system response. Official statements from dermatological conferences recommend that collagen injections should be stopped all together.
Every decade or so a new injection takes centre stage and during the 2000's botulinic toxin - a powerful poison produced by a specific bacteria - was all the rage. It had been in use since the 80's to treat congenital torticollis and strabismus - two medical conditions that can be alleviated when certain muscles are frozen. Botox injections are used to paralyse muscles on the upper part of the face - the area where frown lines appear. They are immediately smoothing, work extremely well and last several months. For a natural look, it's wise to get them done by an experienced, dermatological specialist. They can last for up to 8 months, after which the injections need to be renewed. However some doctors noticed that the long-lasting effect of the injections lessened with every session and patients began to need higher doses more frequently to get the required result. In some countries, small dose Botox injections began to be used to reduce signs of tiredness.
