Reviews Summary
Customers say this serum absorbs quickly and feels lightweight on their skin. Some note an unusual scent initially, though it dissipates quickly. Many reviews mention improved skin texture and hydration. While a few experienced initial redness or sensitivity when first using it, most report that their skin adjusted well with gradual introduction. Common feedback includes observations about smoother application and compatibility with other skincare products. The texture receives frequent mentions, with users noting it glides on easily. Some find it works particularly well in their morning routine, while others prefer using it at night. A small number report it didn't meet their expectations or caused breakouts.

    Staple in my daily am/pm skincare!

    I've been using the vitamin B following my vitamin C serum for a few months, and it has been such a miracle in keeping my skin hydrated and plump. It absorbs extremely fast, and it feels really nice on the skin. I love it!

    Gave my skin back its life

    I've been complaining for so long about blotchy skin and large pores that I never thought I would find a solution at 40 yrd old...but here we are. This serum has been a lifesaver to my skin routine and I feel great. I wish I had a before and after shot to prove it but I avoided photos before using this. Love it!

    A journey to acne-free skin

    The most effective serum for sensitive, acne-prone skin which completely cleared up my skin. I've been using it for a year and am extremely pleased with it.
