I tested the AVL Face Serum which I received complimentary from avllaboratories. The formula contains too many ingredients (more than 50), including silicones, emulsifiers, preservatives and enzymes - this increases the risk of irritation, especially for sensitive skin.
Contains potentially problematic ingredients:
Phenoxyethanol, PEG-400, Dimethicone, Witch Hazel - may cause dryness or compromise the barrier.
There are also fermented and sugar-containing extracts, which are undesirable for rosacea and fungal acne.
Among the advantages are niacinamide, panthenol, amino acids and antioxidants. Suitable for normal to resistant skin.
In my opinion the formula is overloaded. For sensitive or problematic skin, I would choose something more minimalistic.
