My new diamond

This antioxidant serum is really surprising. I used to use a serum before putting on my day cream. Because I had to moisturize my skin. And as usual I changed after the end of the bottle. So I started this new serum from the brand Ipsumalii and I was pleasantly surprised by the effect on my skin: feeling of softness and especially this feeling of not needing to use a very greasy cream to complete my morning 😳 routine! !️ For several days I hesitated whether or not to take a super greasy cream with this serum to complete my morning ritual
I finally decided some time ago not to use it anymore. And I must admit that I did well. There is a feeling of lightness. My skin is usually dry and I had to constantly put on a super greasy cream to feel hydrated. I've been using this serum for 8 months now before putting on a light cream more suitable for my skin
Since the discovery of this serum, I can't do without my diamond 😍

My new go-to serum

I love this serum - light texture and very moisturizing. It’s also rich enough for skiing holidays and light enough for hot and humid weather in Singapore. I only use fragrance free product so this serum is perfect. I use it after my toner and before I apply lotion.

The ONE: my face is finally at peace with oil

First time I use the Antioxidant Booster Serum was at night; I woke up next day with a smoother and more even skin face. After few days, I was so smitten with this oil-serum that I started using it day and night. The formula doesn't feel oily and it glides onto the skin with ease and it's absorbed quickly. There is no luxury scent here, just what I needed. Interestingly, I am not a big fan of oil as it clogs my pores, but my skin has been responding really well to this formula.

The best part is that it gives me a healthy silky glow: a ray of sunlight in a bottle!
