How did it feel on sensitive winter skin?


I tend to break out when I use oily or heavy products, so I used this hoping for both hydration and a soothing feel. On my skin, it applied gently without irritation and absorbed lightly without feeling sticky.


Because the formula is not transparent, I worried that it might leave color on my face, but it absorbed cleanly after application. I felt that it absorbed well even when my skin was flaky in winter, and it seemed to replenish moisture too.


Was it easy to use morning and night?


I used it both morning and night. After cleansing, I applied Aclean, spray-on toner, HEEDA serum, and moisturizing cream in that order, and the dropper format made it easy to dispense.


In the morning, I tried it before sunscreen, and the next steps seemed to adhere without my makeup lifting or pilling. When patted in, it absorbed quickly, so I could move straight on to the next skincare step.


What changes did I notice after one week?


After using it consistently for about a week after receiving it, I felt that my skin tone looked a little brighter and my complexion looked clearer. Areas with acne scars or faint spots also seemed to fade little by little, so I plan to keep using it.


The product lists liposomal glutathione, niacinamide, turmeric complex, and tranexamic acid as key ingredients. I also confirmed while using it that it is a vegan product and comes in a dark-brown glass bottle with careful sealing.
