A short YouTube monologue debunking the myth that vitamin C (ascorbic acid) and retinol cannot be used together. The speaker explains that irritation—not an inherent chemical incompatibility or pH issue—drives the concern, and recommends that sensitive users choose an ester form of vitamin C (tetrahexyldecyl ascorbate) to pair safely with retinol.
Things that may seem obvious to a dermatologist but are not so obvious to you. Number one Vitamin C and retinols. There is this huge misconception that you cannot use a vitamin C with your retinol at night, and this stems from the fact that ascorbic acid, the active form of vitamin C, tends to be irritating, as does retinol. Additionally, people who think they are chemists like to go further and talk about the ph of ascorbic acid versus retinol fast forward. Those myths have been debunked and yet the fear still goes and perpetuates itself. You can absolutely use a vitamin C with your retinol and it might actually work better synergistically together. But if you're very sensitive, instead of using an ascorbic acid form of vitamin C, the active form, go for an inactive form of vitamin C like with tetrahexyl decyl ascorbate which is an ester form of vitamin C, and marry it to a retinol fear free. Number.
