Having tried several lip oils myself, I find that the texture and hydration power can really vary from brand to brand. For example, the Gisou lip oil felt lighter and more glossy, making it great for those who prefer a subtle shine without heaviness. On the other hand, the INNBEAUTY Project oil was noticeably thicker but super nourishing, which made my lips feel instantly moisturized, especially during dry weather. Price per milliliter is an important factor too. I was surprised to learn that the INNBEAUTY product not only performed well but was also the most affordable option per ml — great value for the quality. The Haus Labs lip glaze felt like a hybrid between a gloss and an oil, offering both shine and hydration in one product, which I found perfect for everyday use. If you're hunting for a lip oil that balances cost, hydration, and glow, I'd recommend starting with INNBEAUTY for budget-conscious shoppers or Haus Labs for a glossy hybrid feel. Gisou is excellent if you want a lighter, ultra-glossy finish. All three can be conveniently found linked in the shop section, so you can easily compare and choose what suits your style best. Beauty math really helped me shop smarter for lip oils, and I hope it helps you too!
