Alpha-Lipoic acid is a natural component that our cells use daily in energetic metabolism. We found Alpha Lipoic acid in almost all food. In terms of skincare, a double-blind study has demonstrated that 5% of Lipoic acid improve photoaging skin. This a beautiful acid that is not commonly unfortunately.
The Science
Double-blind studies are the best demonstration that we have to unveil the true power of an active. In this study, 33 women (around 54 years old) were treated daily with 5% of alpha-Lipoic acid on half of the face and with a control cream on the other half, twice daily for 12 weeks.
After 12 weeks, four methods were used to assess the face: self-evaluation, clinical evaluation, photographic evaluation and laser profilometry. After treatment, they notice a decrease in skin roughness.
There are also reports that it is a potent antioxidant especially when it is converted into dihydrolipoic acid. Because it is part of the energetic metabolism it is most likely a potent antioxidant. I am still cautious because it is not clearly demonstrated when applying on the skin.
My take on alpha-Lipoic acid
I have been playing with alpha-Lipoic acid for quite some time and it is a beautiful acid to exfoliate the skin. I like this acid to use in an anti-aging routine. You double the pros: antioxidant and exfoliation.
At 5% it is potent. What you will likely experience is a burning sensation. On myself, it is not too bothering but be aware of it and don’t worry. Every time, I use it I experience a plant smell too.
Don’t keep the bottle for too long as the solution will turn opaque. This acid is very sensitive to the sun.
Give it a try and tell me what you think about it.
If you want to know more watch talk about it.
