As another piece of my skin care regimen, I couldn't be more impressed. I have really enjoyed how moisturized my skin feels after using this product for hours after application. Also, a nice balance is allowing my skin to not feel as oily, particularly my face. I personally did not experience any redness or irritation! I can't speak for Internal Health benefits as I only used this as a topical product. That said, just like all supplements, I agree with the product description of seeking medical advice before starting such a product.
