Skincare forums are very fruitful sources of information on facial exercises. It's become quite popular with many women, and some share their results with photos.
dN, you've done very well to keep your reactions moderate. I think it's clear to the casual and functional observer what just happened there, so thanks for sharing your careful and interesting n=1 observations, and don't be put off doing the same again in future.
Thank you for the encouragement there Steph and for the heads up on where to look. :-)
I would only add to be careful with increasing volume too much, too fast or too often. I suspect this may lead to damage of soft tissue as may be the case with gaining weight too fast etc also there is a link I provided which substantiates the claim of facial muscle building.
I am actually happy that the alternative views/qualifications have been put forward in this post in order to improve my own view on the matter (which they do). It's just the manner which could be better etc. I hope it doesn't detract from what appears a possible solution for many.
With regards to photo sharing I have learnt to be careful when sharing any personal information online. I understand why before and after photos are important but these are easily faked in terms of aging and other beauty products by labelling an older photo as the younger one. That's why it's never good evidence especially when there is a hint of a product being sold.
Take care.
