Vitamin C Serum Ascorbic Acid 15%

product review positives
This version i got is the 2021 updated formula with Arbutin added in. my fave VitC serum to date. this clear, colourless serum has a thin slightly oily feel, spreads easily. i use this every morning after toner, applying a very generous amount as this serum starts oxidising around 3rd month after opening, so there's no point being frugal with application (yes i do keep it in fridge inside its box). 1 whole dropper on dry face & neck, another 1/2 dropperful on collar, shoulder & chest, massage it for 2-3mins to aid absorption and lymphatic drainage at the same time. as this serum feels like dry oil, it glides easily. need around 5-8mins for it to absorb because im using more than most ppl😅 after i massage in this serum, i'll go make coffee and prepare breakfast to give time for it to sink in. after that i'll go back into my room to finish off with other serums, moisturizer & spf. the 15% ascorbic acid combined with panthenol (soothing ingredient), is the perfect concentration for me. it does not irritate my skin, even if i accidentally apply on slightly damp face before toner fully dried off. this serum recently updated their formula (see pic#1) Arbutin is added in and i really appreciate it as it's another skin brightening ingredient.
product review negatives
like a lot of pure vitC product, this serum oxidises quickly. the clear transparent serum started turning slightly pale yellow around 3rd month after opening (see pic#3: serum at beginning stage of oxidation). so i always use quite generous amount to finish it before it turned brown. i even use this occassionally on stretchmarks around tummy to help fade/lighten the marks. it did not fade the marks totally but alternating this serum with a retinol helped lighten it significantly and improved texture of skin. other than this, it's a good & VERY AFFORDABLE ascorbic acid serum.
