I am a skincare fanatic myself, and I’ve heard about avocados being good for your skin. (I need to clarify, eating not mashing and putting on your face.) The link you posted from the medical spa “Vibrant Skin Bar”, is written by Kristina Cadwell. Cadwell has a masters of medical science and has been working in the “Aesthetic Medical field” for over 10 years. To verify Cadwell’s claim, I found an article with a study done by the National Library of Medicine. The study shows that eating an avocado daily increases elasticity and firmness in skin, no matter the skin type. Another study I recommend was done by the UCLA Center for Human Nutrition.

It is interesting to note that avocados are not all healing. According to Vibrant Skin Bar, the same source used in the original comment, “At the same time, the high lipid content makes avocado comedogenic (pore-clogging).” (Vibrant Skin Bar) Though avocados offer anti-inflammatory and moisturizing benefits that can reduce eczema and psoriasis, we should note it’s not a replacement for medical treatments, or chronic skin conditions.
