"For an ethyl ascorbic acid option, I'd pick the Timeless 10% Vitamin C. Vitamin C can easily be a coin flip on irritation, and the higher the concentration the more effective it can be, up to about 20%, but also the more irritating. For someone who wants to see if vitamin C works for them, you still get benefits at 10%, it's more gentle, and historically vitamin C had been very expensive but this one was relatively affordable. It's their bestselling product, a great option if you want ethyl ascorbic acid at an affordable price point without spending $185 on a vitamin C serum."

All 4 takes from Mad About Skin
Move Over Retinol - TOP 5 ANTI AGING SKINCARE INGREDIENTS
"If you have a more resilient skin type I would opt for a pure form vitamin C and in between a 10 and a 15% strength. If you're shopping in the North American market Timeless does this 10% option which is phenomenal. When it comes to anti-aging these serums are doing a lot more than just fading hyperpigmentation. They're protecting, they're boosting collagen and they're just going to give you that glow up that I think we all deserve."
