jessieloui review for Turmeric + C Enlighten Serum

Love this as a hydrating, brightening serum and how dewy it makes me - my skin drinks it up and instantly i feel hydrated and plump - but in terms of vitamin c im not sure how potent this is. Ive reached out to the brand for a percentage of vitamin c and they will not disclose the strength of active ingredients - which i find dissapointing and strange - their reasoning is because their formulas are patented
