are saying

Frequen-C entered my life and it changed everything (dramatic, but true!). I was blessed to be a part of MBX for this product and it was so rewarding watching this baby come to life from samples to what it is now.

I Trust Teni!!
I just started using this so to be fair, I can’t say much, tho nothing negative to report so far. I’ve used vitamin C before and I’m super excited that this is a stick formula. I feel every time I spend $$ on vitamin C serums, the potency lowers within a few months as the color changes and the product starts to smell weird. This is different. I trust Teni, and I trust Monday Born. I have everything and love, love, LOVE all of the products! I expect nothing less from this one :) I will come back once I’ve used this for a month or so and update you on my results :)

So far so good
I just started using this product so I’m not 100% sure about it just yet. Only thing I don’t like so far is that I feel it’s a bit hard to massage into this skin because it drys quickly so I apple it in sections. HOWEVER I will say my face does look brighter and radiant! It’s also working amazingly at fading my dark spots

Love that it’s in a stick!
Vitamin C is the one thing that I always re-purchase from different brands because I feel like it does what it’s supposed to for a minute and then it stops I’m on my third week of using this and I can already see some spots lightning and I love how effortlessly it blends in.

Not sure yet, but so far, so good!
This is my first Vitamin C product and I’m impressed! It stings just a little bit if I put multiple swipes on, but it’s gentle enough that my skin hasn’t broken out in a rash (I expect a few spots/pimples here and there as it is kind of exfoliating). It’s best applied after Source. Will wait and see!
