Packaging came in a very neat & pristine condition. Bubble wrapped and shipped in a box. All products are sealed to ensure its safety & quality. Took abt 2 weeks to arrive. Happy with the free gifts

I'm impressed...

It's been only a few days since I started using those product, and I already feel a huge change in my skin. I began using this every night before I go to bed, and it feels so light and fresh. My skin has never felt this soft and glowy before until now. I even realize how less oily my skin is when I wake up in the morning, I'm so glad I bought this!

Acne problem has been solved

Perfect for a dry/mixed skin type. My acne problem has been solved since I start using this serum along with the same brand’s peeling pad. Fine lines seem that they are disappearing. Super happy about the results!


This has helped my skin hydrate overnight. My skin has looked less dry and dull in the mornings after using this overnight. Its surprisingly light for a night serum but I find it’s easier for my skin to breathe.

I've been using this product for a little over a week now and i love the results. I use a toner of the same brand then apply this serum and my skin sucks it right up! I love the youthful glow it gives. My skin has been on the more dry side due to antibiotics and it seems both the toner and this serum has been helping. I also have some acne scarring.dark spots under my chin and neck area from picking. After a week or so of using this product I have noticed a significant decrease in the dark spots, as well as faster healing overall! I still moisturize after using this serum though because I feel I personally need more, but that is only because I'm on antibiotics. I use organic Jojoba Oil after the serum and then a moisturizer.
Overall I am Very Pleased with this product and will continue to be a customer!
