There are some ways that could be used vitamin c in topical creams and be effective such as:
- Improving vitamin C stability and reducing the risk of irritation by using anhydrous as a vehicle, which is a topical base cream that contains no water.
- Using vitamin C derivatives is another possible solutions, because it provides similar benefits as the vitamin C (L-Sascorbic acid).
- And also use a combination of both methods and provide synergistic skin benefits with more anti oxidant protection.
Vitamin C Serum
On the other hand you can prepare your own high potency vitamin C serum. Make fresh batches, store them and you will have a good supply of topical vitamin C. But be aware that high concentration of vitamin c can be irritating for sensitive skin.
I recommend that you consult a dermatologist before starting a skin care routine with vitamins.
You can also take vitamin C orally with Multi Vitamins or by eating healthy foods such as fruits and vegetables and get the benefits of it.
Some anti wrinkle creams have potent anti oxidants that can protect your skin from sun damage, boost your collagen and reduce wrinkles naturally, but usually those creams are made of natural ingredients and not chemicals like most products.
