Sheldon Pinnell M.D. founded SkinCeuticals in 1997.

He spent many years researching antioxidants, focusing on Vitamin C’s effects.

He was the one to make a breakthrough in skincare. He was also the inventor of the first Vitamin C serum patent.

It was founded in London, UK, in 2005 as a brand. In 2005, L’Oreal bought the company. Their products are now available in spas and shops around the globe.

SkinCeuticals C E Ferulic Ingredients

Vitamin C is the active ingredient in these c serums. It is found in the pure form of L-ascorbic Acid.

It also contains key ingredients like vitamin E and ferulic acid, antioxidants.

Here’s a breakdown of their serum:

  • 15% pure vitamin C (L asorbic acid) L-ascorbic Acid is a potent form ascorbic acid.
  • 1% vitamin E (alpha-tocopherol). Vitamin E (alpha-tocopherol), a component of the serum’s ability to neutralize free radicals, plays a role. Morgan Rabach, the co-founder of the serum, said that it also stabilizes vitamin C.
  • 5% Ferulic acid. Ferulic acid, a plant-based antioxidant, is 5%. It is also responsible for the serum’s ability to neutralize free radicals. It also serves a dual purpose, lowering the pH of the serum to ensure that it is absorbed into the skin.

Why are SkinCeuticals so Good?

Skinceuticals c e ferulic is perhaps the most well-known and beloved of all their products.

Glamour praised the product and named it the best vitamin C serum in 2020.

Byrdie published another finding in 2020 and claimed that the impressive results started to show in just three days.

It all starts with Dr. Pinnell’s very first patent around the product.

He incorporated three critical criteria for an effective vitamin-C serum in it:

It contains pure Vitamin C: Vitamin C should be taken in its purest form, with a concentration of at least 10-15%.

C E Ferulic uses L -ascorbic at 15% concentration, compatible with most skin types.

It has a low pH: For a topical vitamin c serum that works, it is necessary to have a low pH.

Dr. Pinnell stated that c serums must be below 3.5 pH to be effective.

SkinCeuticals C E Ferulic has pH 2.5-3.

It also contains Vitamin C and other antioxidants: Dr. Pinnell discovered that vitamin C combined with other antioxidants was more effective than ascorbic acid.

The triple antioxidant treatment is their vitamin C serum (C Ferulic). It includes vitamin E, ferulic acid, and ascorbic acid.

Are SkinCeuticals’ products worth the money?

SkinCeuticals is a well-respected beauty brand. You can be sure that their products are backed by significant scientific research.

The product’s quality is a testament to the founder’s pioneered research in the vitamin C serum area.

  • Protect the skin from free radicals by strengthening its protective layer.
  • To reduce the damage caused by ozone, neutralizing free radicals

The dark brown bottle of SkinCeuticals c serum has helped to prevent Oxidation.

This allows it to last longer than other vitamin c serums. It has been tested to ensure that it remains stable for:

  • Unopened for 36 months (3 Years).
  • Once opened, it can be kept open for up to six months.

How to use SkinCeuticals C-E Ferulic

It is essential to apply the serum correctly to get the best results. You should include it in your skincare routine.

  • It is recommended that you use it once per day, and ideally, as part of your morning skincare routine.
  • Apply 4-5 drops to a clean face, neck, chest, and chest. Apply the serum to your face and neck.
  • The skin must absorb vitamin C, so it’s best to apply it before moisturizer and protective SPF. These can be used afterward.

Obagi Vs Skinceuticals FAQs

Can You Eat Vitamin C Instead of Using a Serum?

Vitamin C is not likely to be absorbed into your skin when you consume it.

Can You Use Vitamin C Serums with Retinol Creams?

Obagi and Skinceuticals serum can be used with retinol creams, but it is not recommended that you use them simultaneously. You can use one with your morning routine and the other with your evening skincare routine.

Ascorbic acid can cause mild skin irritation (part of its ability to stimulate collagen production).

It can make matters worse if you apply a retinol lotion immediately after. It is a good idea to distinguish the time each cream is applied.

Vitamin C can be used in conjunction with a moisturizing sunscreen applied afterward. This ingredient is often used as part of a morning routine.

Retinols, on the other side, contain retinoids. These retinoids are believed to be less effective when exposed to light. They are recommended to be used at night.

Can I use the Obagi C20 serum?

Different concentrations of vitamin C are available in the Obagi C series.

C20, the highest concentration, is used to treat advanced skin conditions.

It is best to start with the lowest concentration of C5 and then move up once your skin has adjusted.
