How Vitamin C Works
Scars form as part of the healing response to a wound in the skin. Collagen is an integral part of this process as its a necessary component in the new tissue required to heal a wound. And vitamin C is a key player when it comes to creating collagen. Even though collagen and wounds are usually discussed in the context of repairing fresh injuries, since collagen helps make healthy tissue, it can impact older scars as well and improve their appearance. And since scientists already know that topical vitamin C can help reduce post-inflammatory hyperpigmentation , it stands to reason that vitamin C could also help minimize the discoloration of acne scars.
That said, while you dont necessarily want to apply topical vitamin C directly into an open sore, you also shouldnt wait for a rainy day to begin treating your acne scars. While studies have shown the effectiveness of a combination of topical vitamin C and hyaluronic acid on scars more than four weeks old, theres not a lot of data demonstrating how well vitamin C works at reducing long-ago acne scars. The takeaway here is: Dont wait to start treatment.
Paulas Choice C15 Super Booster
This is another cult favorite, and for good reason. The PC Vitamin C is one of the best dupes for the Skinceuticals CE Ferulic. However, it does have a lot more ingredients that the Skinceuticals one, so it may not be the best for sensitive skin types.
But, as anything with Paulas Choice, theres nothing but great ingredients in their products, so all those extra ingredients serve a purpose. They also include what the ingredient does in parentheses which is so nice!
Paulas Choice C15 Super Booster Ingredients:
Water , Ascorbic Acid , Butylene Glycol , Ethoxydiglycol , Glycerin , PPG-26-Buteth-26 , PEG-40 Hydrogenated Castor Oil , Pentylene Glycol , Tocopherol , Sodium Hyaluronate , Hexanoyl Dipeptide-3 Norleucine Acetate , Lecithin , Ferulic Acid , Panthenol , Bisabolol , Oryza Sativa Bran Extract , Propyl Gallate , Sodium Gluconate , Sodium Hydroxide , Phenoxyethanol , Ethylhexylglycerin .
As you can see, this serum has the same 3 main ingredients: Ascorbic acid, tocopherol and ferulic acid, so its a great alternative to the Skinceuticals CE Ferulic! Of all the dupes, the Paulas Choice booster is the most expensive, and it also has a lengthy ingredients list, which can be a problem for sensitive skin. However, the ingredients in the C15 Booster are amazing for the skin. From antioxidants to hydrating and soothing ingredients, this serum packs a punch.
Pros
- Can be mixed in with other serums or moisturizers
Cons
Should You Use Vitamin C Every Day
Vitamin C can be used every day, as long as it is tolerated well and not irritating the skin or causing an adverse reaction, says Pritzker. However, if youre new to the vitamin C serum scene, it may be best to start at a lower concentration or apply it less frequently because it can cause irritation.

What Can Vitamin C Do For Your Skin
In skin care, a great vitamin C tip is that it can do a few really helpful things if you know its use. First, vitamin C can actually inhibit the production of melanin, the pigment in the skin, which makes it a crucial ingredient for managing hyperpigmentation and generally evening out skin tone.
Second, vitamin C acts as an antioxidant, which means it can help neutralize free radicals. These are unstable atoms that form as a result of exposure to environmental stressors like UV rays and pollution. Over time, free radicals can cause oxidative stress, which can harm the skin and cause premature signs of aging. Using sunscreen daily along with a potent antioxidant like vitamin C is the best way to protect yourself from damage due to free radicals.

What Were Looking For
Formulation: All of our experts agree: Formulation is paramount to vitamin Cs stability. The more stable, the better, because you reap all of the glow-inducing benefits. A product must be formulated carefully to enable sufficient delivery to the skin, Dr. Kenneth Howe of the Wexler Dermatology Group explains. As for how much vitamin C should be in a given formulation, Lal recommends at least 10 percent. Less than that and you dont get the full benefit of the product, and over 20 percent, you dont get any additional benefits and are more likely to experience irritation. However, this doesnt really mean much when it comes to derivatives because, according to Lal, once the derivatives hit the skin, a 10 percent concentration is much closer to 3 or 4 percent.
Packaging: Your vitamin C should come in a dark or opaque bottle. This helps prevent oxidation, which happens when it is exposed to sunlight or isnt kept in an airtight bottle. It will be obvious that this is happening because the formula will darken in color. To prevent this, our experts recommend keeping it away from sunlight and storing it somewhere dark, along with closing the bottle tightly.

More Faqs About Ascorbic Acid & Alpha Arbutin

Can I use Vitamin C Suspension 30% with Ascorbic Acid 8% + Alpha Arbutin 2% and Glycolic Acid Toning at the same time? It may not be necessary to apply both Vitamin C products in the same routine. We would suggest alternating between Glycolic Acid and Pure Vitamin C and waiting until your skin has adjusted to one before introducing another.
Can Ascorbic Acid 8% + Alpha Arbutin 2% at the same time as The Ordinary Buffet? It is best to not use Peptides in the same routine as the following products: Direct acids, LAA and ELAA .
Can I use the Ascorbic Acid & Alpha Arbutin in the evening and the Niacinamide in the morning? Yes, you can.
I use the Ascorbic Acid + Alpha Arbutin after Hyaluronic Acid and I get residue-type flakes. Is there something that Im doing wrong? Pilling often occurs due to many different reasons, for example, the amount of the product being applied, consistencies of the products being used in conjunction, the total number of products being applied, etc.
You may be applying too much product to your skin. Your skin can only absorb a certain amount of product, and any excess will be left on top of the skin so that when the next product is being applied, it rubs off. We recommend using 1-2 drops of each product, massaging it into the skin until it is fully absorbed in order to move on to the next.
