Side Effects After Botox in Forehead - Are They Permanent?

Hi Kingston.  Bruising after Botox is quite rare for experienced injectors - at least in relation to the possibility of bruising with dermal fillers.  

Whether this is bruising (or hemosiderin staining) as mentioned below, there are alternatives that have not been addressed.  Within two days of a deep bruise from any injection, we use pulsed dye lasers to quickly reverse the bruising.  After two days though, the treatment window closes and the bruise cannot be reversed easily.  The bruises typically resolve with 48-72 hours after V-Star pulsed dye laser treatments.

If the bruising has been there for quite some time (hemosiderin staining), then a q-switched Nd:Yg laser may be more appropriate.  We have used these lasers to remove staining from injection procedures as well as from sclerotherapy injections.  Hope this helps and good luck.

It is impossible to answer your question without seeing you in person and examining the lesion with high magnification.  What is unusual is to believe that there is a growth that the injection caused.  The needles commonly used to inject Botox are so tiny in diameter that there are no marks left.

It is impossible to know exactly what is going on without examining you.  In general, however, it sounds like you may have post-inflammatory hyperpigmentation.  After any injections you can have bruising.  Bruising can take 5 days to even 2 weeks to completely disappear, depending on how big and how deep the bruise is.  The bruise can also cause some inflammation in the skin.  This can make it look a little red at first but it may look brown after the inflammation has gone away.  This is the same thing that happens when you get a brown mark after a pimple or a scratch.  With some time it should fade to your normal color.  Be sure to use sun protection as sunlight will prevent this from fading and could even make it worse.

Bruising is always a possible side effect with Botox injections.  Bruising generally resolves over weeks.  Some people develop skin darkening after procedures.  This is called post inflammatory hyperpigmentation (PIH) - it's actually increased pigment in the skin.  PIH goes away on its own- but it can take weeks to months.  If you want to speed up the fading process, you can get a bleaching cream from your dermatologist.

Botox injections can create some bruising that usually go away in a few weeks. some bruising may "stain" the skin and the pigmentation (Post inflammatory pigmentation)  may be present for few more months. Some topical bleaching creams may help. you may want to discuss it with your doctor. 

Botox action lasts 3-4 months on average, then dissipates.  The effects of Botox are not permanent.

Since you had some bruising in the area, it could have left some post-inflammatory pigmentation, that can last several months depending on the amount of pigmentation in your skin.

It is important to look at the before and after photos to determine if that mark was possibly there previously.  Also, if it is on the left-hand side, where the face is regularly exposed to the sun from the car window, that may exacerbate post-inflammatory pigmentation.

The mark that you describe could be a hemosiderin pigment stain of your dermis.  When people get bruises the red blood cells burst releasing the hemosiderin pigment that sometimes stains the skin leaving a mark.  In most cases the mark lightens and disappears with time.  You may want to give it a month or so and if it doesn't improve see the MD that injected your Botox for further advice and treatment.

Bruising and pigmentation after your Botox injection should be temporary. There is nothing that you can do to accelerate the healing process. Fortunately, this is very rare.

Pigmented spots at the site of botox injections are due to bruising. They usually fade with time and only rarely are permanent.

Your bruising at the injection site is most likely due to post-inflammatory hyperpigmentation which will be temporary. It is not an effect that is related to the Botox and is not permanent.
