First of all: I have been a big fan of pure squalane oil from another brand for probably ten years now. I use squalane on the eye area, on the rest of my face after serum and moisturizer, in the lengths of my hair, and on dry cuticles. Squalane is a so-called stable oil that does not oxidize easily, and it should be able to penetrate quite well into the skin compared to oil from e.g. rosemary and olive tree 🌿 In Dual Essence from Sensai, there is fortunately a portion of squalane, how much is uncertain, but it is at least first on the ingredient list. Unfortunately, olive oil has also snuck into the serum. A Google search shows that olive oil is not particularly stable and should be stored cool in a light-tight container to increase shelf life (the latter also applies to squalane). This bottle is made of uncolored glass, so that should be taken into account. Olive oil is also not a first choice for use on my face - there are simply better ingredients, like the mentioned squalane. Otherwise, on the ingredient list, we unfortunately also find other less friendly ingredients (that maybe not everyone can tolerate either) - linalool, dimethicone, perfume, alcohol, and various plant extracts. Several of these are known allergens, and alcohol is directly drying 😩 It goes a bit against the product's purpose, to provide lots of moisture! The perfume, however, gives the product that little extra in its own way - it smells like an exclusive spa, and I can somewhat like that! Just not on my face, and definitely not at night 🙈 The perfume would have been lovely in a shower gel, for example 💕 I have therefore used Sensai Dual Essence occasionally on my face during the day to get a bit of variation in products, and in the lengths of my hair. That way, I get the nice scent in a suitable amount and don’t have to think too much about whether I will react to any of the ingredients. The glow it gives is also nice, I guess dimethicone contributes a bit there. The serum also provides a nice base for face makeup 💃🏻 It is written about the ingredient koishimaru silk royal, which Google tells me is a type of silkworm that spins particularly thin silk threads. Uncertain what this does for the skin? 🤔 In my world, anti-aging products are typically exfoliating and thus renewing, like e.g. retinol and various acids. The price is also something quite unique for me 🙈 It is nice to treat oneself to something extra beautiful from time to time, but for me, function is most important when it comes to skincare and cosmetics in general 🥵‍♀️ Here I don’t quite see what makes this serum worth the money. Because in my opinion, you can get good results from products that cost a tenth of the price or less 🙏🏻 #sensai #sensaidualessence #lykoinflutester
