C5 Super Boost Moisturiser is made with two highly stable types of vitamin C: 3-O ethyl ascorbic acid (3%) and ascorbyl glucoside (2%). The 3-O form is both water- and oil-soluble, while ascorbyl glucoside is water-soluble. Together, they deliver multi-level vitamin C benefits. The skin converts 3-O ethyl ascorbic acid and ascorbyl glucoside to L-ascorbic acid, the most research-backed form of vitamin C. L-ascorbic acid helps fight off free radicals and external stressors, lessening the ageing impact of both.
We chose these types of vitamin C because of their stability, efficacy, and global regulatory compliance which helps ensure we can offer these amazing products to Paula’s Choice customers around the world. They’re both highly stable and work on all skin types, including those who tend to be a bit sensitive to our other vitamin C products.
Yes, C5 Super Boost Moisturiser is suitable for rosacea-prone and sensitive skin, but we recommend starting slow and using it 2-3 times per week in case you experience any redness or sensitivity. Let skin adjust to the new product, then work your way up.
Yes, C5 Super Boost Moisturiser is suitable for acne-prone skin, especially when used as part of a complete anti-acne skincare routine.
Yes, you can use two or more vitamin C formulas together. For example, you can use C5 Super Boost Moisturiser with other vitamin C skincare products. By combining vitamin C products, you get better free-radical protection and environmental defence, plus improvements to discolouration, wrinkles and loss of firmness. Try using them in the morning, always following with SPF.
Yes, C5 Super Boost Moisturiser is safe to use under and around your eyes, but we recommend avoiding eyelids and along the lower lash line.
Research shows that vitamin C works even better with other active ingredients like niacinamide, retinol, peptides and AHA/BHA. Here are a few of our favourite combos:
Vitamin C + Retinol: Retinol (in the form of retinyl palmitate) and vitamin C (ascorbic acid) are naturally present in skin, where they work together to keep it healthy. Vitamin C and retinol can coexist and maintain their benefits in a single formula, or they may be formulated separately and layered.
Vitamin C + Peptides: Ascorbic acid plays well with almost all peptides, working to protect skin and help visibly repair damage. The only exception: copper peptides. These tend to oxidize ascorbic acid, making it less effective on skin. When using vitamin C and copper peptides in your routine, we recommend using one in the morning and the other at night to ensure maximum effectiveness.
Vitamin C + Niacinamide: Together, vitamin C and niacinamide form a powerhouse combo that addresses uneven tone, wrinkles, loss of firmness and dullness. All skin types will see radiant, smooth, more even, and younger-looking skin when pairing these two ingredients.
Vitamin C + AHA/BHA: The exfoliating action of AHA or BHA sheds build-up of dead skin cells to help vitamin C sink into skin better. Using AHA/BHA before vitamin C helps it be more effective.
