Your budget isn't the issue, and neither is the volume of creatives. The problem is structure and how the market actually reacts to perfume advertising.
Ten creatives in one ad set means Meta is spreading that limited budget across too many variables. None of them get enough spend to leave the learning phase. I'd consolidate down to three or four of your strongest performers and let them actually breathe.
Perfume in India is a genuinely tough category - you can't convey scent through a screen. So every ad has to sell the feeling and the status of wearing it, not the product itself. Each creative needs to answer one question: who does this person become when they wear this? That's what drives conversions for fragrance, not ingredient lists or close-ups of the bottle.
For the first few days, ignore ROAS completely. Watch thumb-stop rate, hook rate, and add-to-carts. If people are stopping and clicking but not buying, the website is the bottleneck. If nobody stops, the creative is the problem.
A daily spend around that level is workable, but you need at least a week to ten days of clean data before drawing any conclusions. A few days isn't enough for Meta to find its rhythm, especially in a competitive space like this.
UGC can work well for perfume, but only if it feels aspirational - someone receiving it as a gift, wearing it on a date, getting a compliment. Lifestyle over product, every time.
You're not far off. The foundation is there - it just needs a structural reset.
