Segall AI, et al. (2008). Stability of vitamin C derivatives in topical formulations containing lipoic acid, vitamins A and E. Swindell W et al. (2021). Tetrahexyldecyl ascorbate (THDC) degrades rapidly under oxidative stress but can be stabilized by acetyl zingerone to enhance collagen production and antioxidant effects.
Look for a formula with at least 10% vitamin C and a maximum of 20%. Anything less may not be effective. Anything over 20% could lead to irritation, and research says the benefits of vitamin C don’t increase after that threshold anyway. We have better news regarding the three magic abilities of vitamin C: there is in-vivo (tested on real people) data showing that SAP does have photo-protective (aka antioxidant) properties, though less than pure AA. SAP might also aid collagen boosting;in-vitro (made in the lab) data shows that it works, but is less effective than another vitamin C derivative, called MAP (that seems to be as effective as pure AA). As for skin-brightening, there is a trade publication with in-vivo data showing that SAP can fade brown spots. Vitamin C is safe to use for most skin types, but it’s still a good idea to do a patch test before applying serum all over your face. These natural molecules aren’t bad on their own, but they can become a problem when they build up. In high numbers, they can break cells down over time, contributing to illness and aging.

Anyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable. Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less goodat 350-400 nm (UVA I) range. Regular sized Titanium Dioxide also has a great safetyprofile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters). glycolic acid, a type of alpha hydroxy acid (AHA), can work well for hyperpigmentation but can sometimes be irritating to sensitive skin Super Facialist is a cruelty-free brand, does not test on animals and never ask others to do so on their behalf. They strive to deliver formulations that help the skin achieve its perfect balance, plus optimum radiance and health. I love a two-step cleanse, so I chase this with a gel formula each evening – it makes super-light work of melting a full face of make-up, allowing that second cleanser to focus on pore-perfecting. (Need a suggestion? Try the collection's corresponding Micro-Polish Facial Wash, which contains biodegradable microbeads.)

We have also browsed through Prospector to see what manufacturers sayabout their algae. There is, for example,an algae extract trade-named Lanablue that comes fromblue-green algae (green algae is rare, less than 1% of the total macroalgae in the world) and is claimed to have retinoid like effects(i.e. reduce wrinkles, smooth skin) but without the side effects (though it seems now that the INCI name of Lanablue was changed to Aphanizomenon Flos-Aquae Extract). According to Palm, if you’re new to vitamin C, start on the lower end of the spectrum and work your way up to avoid any possible irritation. What vitamin C is best for oily skin? Burns EM, et al. (2013). Differential effects of topical vitamin E and C E Ferulic® Treatments on Ultraviolet Light B-Induced Cutaneous Tumor Development in Skh-1 Mice. Vitamin C in the form of L-ascorbic acid may be the best option for oily skin because it’s both lightweight and water-soluble. What vitamin C is best for combination skin?
