As The Simple Serum contains Ascorbyl Glucoside, a more stable and water-soluble derivative of pure vitamin C that is less potent but better tolerated in sensitive skin, a percentage is not noted. The Simple Serum targets multiple skin concerns, including those addressed by typical vitamin C serums: A blend of ingredients to neutralize skin-damaging free radicals, boost collagen production, encourage brightness, clarity and glow.

Vitamin C may diminish melanin in the skin, and it is highly recommended to use a broad-spectrum SPF as the last step in your morning skincare.

The Simple Serum
This is my favorite product in the Simple Range along with the Oil. I’ve been using it since its launch and I haven’t found anything I love more in terms of results and texture. I love the fluid, non-sticky feel. Thank you! I’m now on my fourth bottle.

The Simple Serum
I haven’t used the Simple Serum for too long but can already see a major boost in the hydration of my skin. Absorbs very quickly, which I love. Thank you for this!

The Simple Serum
This is the best serum I've ever used. Perfect for my combination skin. Most serums either sit on skin and don't absorb completely making skin too oily and clogged or they're not enough for tackling wrinkles and dry patches on skin. This one doesn't cause any breakout and makes you glow. Was able to see a great difference in 3 days.
