C20 Tetraforce Activator by Add Actives
Everyone has at least one holy grail item in their skincare cabinet, am I right? I believe I might have found mine! According to Add Actives, the C20 Tetraforce Activator is »one of the highest quality Vitamin C Concentrates available«. It’s supposed to have a gentle but effective formula that acts against hyperpigmentation, uneven texture and skin tone, fine lines and other concerns we stumble upon as our skin starts to age. It contains an antioxidant called ascorbyl tetraisopalmitate, which is actually a vitamin C derivative.
Recently, the brand owner gave away Add Actives Tetraforce vitamin C samples as thanks for the contribution to one of their questionnaires. I was happy to receive my sample very fast and I started using it that same day.
