WHY VITAMIN C MATTERS

Vitamin C is one of skincare’s most celebrated ingredients for good reason. It helps visibly brighten, improve the look of uneven tone, and support skin’s defense against oxidative stress. But here’s the thing, not all Vitamin C works the same.

The problem with most vitamin C?


Many formulas use L-Ascorbic Acid, which can be unstable. It oxidizes quickly (meaning it loses potency), may cause irritation, and can lose effectiveness before you finish the bottle.

Radiant Skin Magic

Mutha No.1 Serum is wonderful! I've never experienced such transformative results. This serum's lightweight formula effortlessly absorbs, leaving my skin feeling like silk. But it doesn't stop there -- my complexion is noticeably brighter and more even. Trust me, your skin will thank you!

Okay mutha

Expected this serum to be a typical basic formula wherein the logo was the main selling point but man is it good :(. Noticed a brighter complexion the next day good. Has a smell, which imo you know it's a solid formulation if it has a smell, so no complaints here.

The real deal

No cover-up perfumes and chemicals, just pure, unadulterated power. The texture is silky and smoothing, the color is a pale peach, that goes on clear. My skin felt hydrated and plumped immediately after the first use. Overnight, it heals and calms your skin, and you wake up with a glowy bright appearance. I am impressed with this serum, and know it's worth every cent.

I've been using MUTHA No. 1 Facial Serum for a few months now, and the results are incredible. My skin feels noticeably smoother, more hydrated, and has a radiant glow I haven't seen in years. The texture is luxurious, absorbs beautifully, and layers perfectly under makeup.

You can feel it working!!

I could feel it going to work almost instantly. It wears great under my moisturizers and my foundation with no signs of buildup. I have very oily skin, and this serum even kept my shine down! I am in love with this product! My skin was noticeably fuller, supple, and I could even see a difference with the lines on my forhead or rather the lack of them. I will definitely be adding this to my skincare routine! I love it!!

FAST RESULTS

My main focus is fine lines on my forehead and there is a viable difference in the short time I used the product, which I was really amazed by. In addition, my skin tone visibly smoothed out around my cheekbone area (dark spots) and my overall complexion improved. I have tried many different serums and even after long term use, hadn't seen the results I did in the short time I used this.
