Vitamin C serums?

[Anonymous]

So my aunt have been using a diy "vitamin c" cream. She buys vitamin c supplement tablets and grinds them into fine powder and then mixes it in creams/gels, hense tablets are cheaper than serums. But one of her friends ( she's a doctor by the way) told my aunt that it won't work cuz vitamin c is water soluble, it won't work no matter how much of it you put on your skin. And it made me wonder, does that mean that vitamin c serums are a scam?

I think it’s a scam. One can take a pill and ingest Vitamin C. And, they are selling that stuff with weed in it now too. Hers have weed in it ⁉️

She’s wasting money. But her flowers. Self-appreciation and feel better exercise. It is a cry for attention or love….
