"The superhero of skincare ingredients finally captured in a bottle in its pure, fully potent form. This serum has no equal on the market."
– M. Scottson, Pharm. D

This groundbreaking, award-winning serum redefined the standard of how Vitamin C serums should look, feel and perform––which is why it’s earned a cult following from almost every beauty editor in the industry. This water-based serum is bottled in a 100% oxygen-free and light-free environment, capturing Vitamin C in its absolute purest natural form.

Most clients see visible improvements to skin tone and brightness in 14 days. Significant improvements to dark spots and to the thickening of skin's collagen layer can take a full bottle or two when used alone. These improvements are accelerated when paired with the Enzyme-Active Retinol Serum.

Technical specifications:

  • Formula pH: 3.46
  • Key Ingredient Composition: 10% L-ascorbic acid
  • Vehicle: Aqueous solution
  • Note on composition and delivery mechanism: Due to the accumulation effects of topical ascorbic acid and the eventual saturation point as documented by Pinnell et al. (ref.), the serum has been calibrated to 10% L-ascorbic acid with a pH of 3.46, which is sufficient to reach the LAA saturation point within 3-4 days of daily application, while also reducing any irritation effects experienced with lower pH and/or higher concentrations of L-ascorbic acid. In an aqueous solution of this nature, additional absorption enhancing ingredients are unnecessary.
  • Stabilization technology: Anaerobic manufacturing and bottling using a patented (US Patent # 20240359846A1) process under nitrogen blanket. HPLC assay tests confirmed zero loss of L-ascorbic acid after 60 days of storage at standard ambient conditions (SATP).
  • Note on the absence of ferulic acid: Ferulic acid is responsible for the infamous odor experienced in all ferulic acid-based serums as well as the primary irritant. Though it does increase UV protective properties of L-ascorbic acid serums, we believe this task is much more appropriately handled by broad-spectrum sunscreen––making the inclusion of ferulic acid unnecessary and particularly unwarranted given its significant drawbacks in a serum that is stabilized by its packaging technology.

All cotton. No swamp butt in this heat
Color: Black&grape Purple&ash Gray&white&pink&beige, Size: Medium
Absolutely love these!! All cotton, breathable and comfortable. A little too high waisted but I was expecting boy shorts not briefs. The front crotch seam is weird but doesn't show. Neither does anything else 😀

Most comfortable underwear EVER!
Color: Black&grape Purple&ash Gray&white&pink&beige, Size: X-Large
As close to an actual men’s boxer brief you can get. Soft and stretchy but maintains their shape. The legs aren’t too tight and they don’t roll up and the waist doesn’t roll down. The box says to hand wash but who has time for that? They washed and dried just fine.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
