    I have been using IREN’s brightening skin serum since 2 weeks now and it has worked miracles. Its keeps your skin hyderated with natural oils and works on dark circles as well.
    This product really stands by what it says.

    I use this for my marks and spots on my face. I feel like this is a saving grace for my face. It has helped reduced my pigmentation on my face however it has not completely got rid of it. I feel like this prevents me from getting future spots also. It smells amazing and is super smooth.

    I love this Star Light Serum! Sadly i’ve been in the sun a lot lately, so i’ve seen more sun spots coming to the surface. I do occassional IPL laser treatments to help get rid of them, but this serum is a great thing to use in between to keep them at bay. After using if for awhile, my skin felt fresher and more awake as well. I’m going to get some for my Mom as she has some bad sun spots forming too.

    I love this serum. It gives my skin a glow and it doesn’t agitate my acne. I have been using it for a full week now 2x a day in the morning and at night. My face looks and feels moisturized so I am no longer using an additional moisturizer, only my sunscreen. Will definitely buy again.

    Love this skin brightening serum. Seemed to take away some of the hyperpigmentation I have from acne and sun damage to give me a more even complexion.
