good but I use it twice in a month

I'm not a consistent user of products, I fall off the wagon sometimes. It's not even been 3 months since I purchased the product and it was already changing texture, turning slight yellow. It's airtight packaging btw, feels like dr V definitely cut corners making this product. I get it it's affordable, but so is minimalist, and I much prefer their salicylic serum as it doesn't turn this quickly. Works fine, minimalist was more effective imo, this works too but the product turning so quickly put me off, especially since this is supposed to be made by a well known famous doctor/youtuber.
