Definition

She starts off very powdery, but after about half an hour or so, the citrus notes start coming through. I definitely smell more bergamot than manderin. It's such a beautiful and tasty combination of the orchid scents with the citrus ones. She is pretty strong too. She has a medium range. The longevity is pretty good too, around 6 hours or so. I had already gotten 2 compliments about this perfume today, so I guess I'm not the only one who likes her. Maybe it's because I am relatively new into the scent scene, but I think she can be worn at any occasion, any type of the day, even if she definitely leans a little more daytime. She reminds me of a tasty fresh drink on the beach, even though I hate the beach lmao. Love this one! When she runs out, I am definitely making sure I have a second bottle on hand before then!

This is perrrfect!!! I bought a bunch of Christina Aguilera perfumes and honestly was debating whether to get this or skip it because notes didn't seem like something I'd enjoy. I still put in in my cart. It arrived. Oh my goodness!! This is smooth, soft, powdery, lactonic like the most luxurious body milk or body cream. Like your second skin but way way better. I've tested thousands of perfumes and own close to 300 but Definition is my literal No 1!! The only other scent I loved this much is Love, Chloe - they are similar but Chloe is a tad bit spicy. Definition is super affordable, long lasting, ultra feminine tender pink perfume, like a fluffy blanket and even serves as a replacement for Love, Chloe. I'm over the moon!!! I'll be buying back up bottles.

Christina Aguilera Definition is a fragrance that feels like a soft embrace. Although there’s no rose listed among the notes, it gives off a pink vibe – not the flower, but the color. It smells smooth, delicate, and unmistakably feminine. There’s something very comforting about it. It blends sweetness with a gentle warmth that’s never overwhelming. I love how it makes me feel – elegant, positive, and subtly confident. It has that “my skin but better” quality, like wearing a soft, pink veil that enhances your mood. I reach for it on days when I want to feel graceful, fresh, and put together without trying too hard. It’s a mood-lifter – simple yet full of personality. To me, this perfume captures the essence of quiet femininity with a modern twist.

This has the same creaminess factor that MontBlanc has. The orchids, heliotrope & musk I feel give it that creamy sorbet undertone and the apple on top gives it a lolly kind of smell. It’s my favourite of her line so far and it reminds me of something I used to wear in the early 2000’s and I can’t remember for the life of me what it was, perhaps something Avon since my mum worked for them around that time. I only discovered this at the beginning of 2026 and I’m in love with this scent. I’ve been wearing this in the hot weather and it projects and lasts a long time on my skin and even longer on my clothes. This one will stay in my collection as a staple forever

I really like this one from Christina. Probably one of my faves. Next to Red Sin. I have to say this one really lasts on me. Even on sunny/hot day's. It has a really soapy and floral scent to it. HEAVY on the soapy/clean scent. I haven't ever really owned a heavy "soapy" scent till this one. It's not like anything else in her lineup. It's a good clean scent, and one that sits close to the body does not radiate very far so if you're looking for something to smell yourself and you enjoy a clean soapy floral clean scent this is great if you're a fan of her collection like I am.
