Details & care

What it is: A serum that boosts overall skin conditions, improving pores, sebum, firmness, fine lines, skin texture, skin tone and irritation.

What it does: The serum makes your skin soft and smooth and helps even out your skin tone and texture. It features a lightweight, nonsticky texture that absorbs quickly. It's perfect for those with complex skin concerns that want to improve overall skin conditions at once. It is the ideal first-step skin booster that can be paired with other products.

How to use: After cleansing you may use this serum as the first step of skin care. Spread the serum on the entire face and you may apply several times to amplify the effect of the next serum or ampoule

Must Have

[This review was collected as part of a promotion.] This product is great in my personal opinion. I definitely feel as though it helped with not only hydrating my skin, but also alleviated some redness which in turn got rid of some irritation!

Become a staple in my skincare

[This review was collected as part of a promotion.] I’ve been using this product so far for over a year and it has definitely made a big difference in the overall texture of my skin. It has helped a lot with making my skin softer, smoother, and more even colored. I have not experienced any breakouts or oiliness even paired with a moisturizer. This has become a staple in my routine and will definitely rebuy and recommend to friends in the future!
