Beginners Guide To Skincare – Vitamin C {Ascorbic Acid}

Hey, my beauties. I’m still discussing a few ingredients and “skincare steps” under my Beginners guide to skincare series and today I share some information on Vitamin C. An ingredient that’s gotten quite the reputation for being a little difficult to work with because of its unstable nature.

What is Vitamin C?

Oranges, lemons? Yes!  But it’s also an amazing ingredient in skincare. It’s a powerful antioxidant that helps fight free radicals and UV rays against the sun, helps to increase collagen production in the skin and gives the skin that brightness that most of us want all year round.

Like I mentioned above, Vitamin C is an unstable ingredient. This means that it’s very sensitive and can change easily depending on factors like temperature, air, light and the environment. It’s an ingredient that can go bad pretty quickly, so packaging and the way it’s stored is also important.

One can find more stable forms of vitamin C, known as derivatives. These derivatives are a little easier to work with, won’t go bad too quickly and will work better with other ingredients. Derivatives can come in oil – and water-based forms and are less harsh on the skin than the pure form of Vitamin C. There are so many different Vitamin C derivative skincare products on the market.

List of Vitamin C derivatives

  1. Tetrahexyldecyl ascorbate (THD ascorbate)
  2. Magnesium ascorbate Phosphate (MAP)
  3. Ascorbyl Glucoside

The best way to spot these is to read the ingredient list.

Below is a list of Vitamin C products in my collection

1. Sunday Riley C.E.O Cream

A hydrating moisturizer that infuses skin with high-potency, advanced vitamin C (THD ascorbate) to fight the first visible signs of ageing while providing powerful antioxidant support. C + E Protect & Repair Moisturizer infuses five percent advanced, oxygen-stable tetrahexyldecyl ascorbate (THD ascorbate) into the skin- the gold standard form of vitamin C.

This rich cream is thick, so a little goes a long way. It’s hydrating and for this reason, restores the skin’s radiance. It’s also one of the best on the market at fighting signs of ageing.

Hubby and I have both been using it for the past month and we both really enjoyed it.

2. The Ordinary Vitamin C suspension with HA Spheres

This one has a pretty high percentage of Vitamin C at 23%. It has a thick serum consistency that feels slightly grainy but it’s because of the vitamin C powder that they add to the product.

I loved using this in the evening on days when I want to take a break from acids or my Vitamin A products. My only issue was the grainy texture. You need to spread it well in order for that graininess to dissolve. I actually felt a tingling sensation with this product and sooth my skin with rosehip oil t of ease my skin.

I had it for a couple of months and it must’ve gone bad because my skin reacted to it after a while. I broke out into these tiny inflamed pimples around my chin and mouth area. So just something to note.

3. Sunday Riley | C.E.O. Glow Vitamin C + Turmeric Oil 

Instantly absorbing, with advanced Vitamin C (Thd Ascorbate), turmeric, and evening primrose oil, to brighten, hydrate, and glow. Recharge your radiance with this glow-giving Vitamin C Oil. Advanced Vitamin C, blended in a base of cold-pressed, red raspberry and evening primrose seed oils, gives your skin a fresh burst of luminosity. Golden turmeric extract, rich in antioxidants and calming compounds, improves the look of skin evenness.

I haven’t opened this product yet but eager to start using it as I’ve read so many great reviews.

4. 111SKIN Vitamin C Brightening Booster

Reduces the appearance of hyperpigmentation and discolouration. Highly concentrated formula for quick and effective results. Leaves the complexion luminous and evenly toned.

I’ve only used this product for a few days. Will have a detailed review up soon.


How to use Vitamin C in your skincare routine

Vitamin C is luckily not as intimidating as Vitamin A. It doesn’t matter what age you are or skin type you have, you can enjoy the benefits this ingredient has to offer. If you are new to vitamin C, I would advise you to start off with a low percentage and work your way up. Alternatively, you could try out a Vitamin C derivative product as these are less irritating and suitable for sensitive skin.


When to use Vitamin C

You can use it either in the AM or PM, it’s all up to you. I, however, prefer using it in the Am ( ALWAYS use a sunscreen) because of its antioxidant properties and its ability to fight off free radicals and prevent sun damage during the day. It essentially creates a barrier for your skin during the day.


What other ingredients does it work well with?

Vitamin C works well with Niacinamide, ferulic acid and vitamin E. If you’re using it with Niacinimide then be careful. Using a pure Vitamin C percentage or anything between 10-20% might irritate the skin. You could also use one in the morning and the other in the evening.


Final thoughts

This is an amazing ingredient and one that everyone needs in their routine. Its ability to brighten the skin, help with hyperpigmentation as well as ageing is enough reason for me to continue using it.

You can tell a difference in the brightness and radiance of your skin after 2-3 weeks of use. Use it continuously and after 2-3 months you’ll see the benefits such as tone improvement and a decrease in the appearance of fine line and wrinkles.

Do you have this ingredient in your skincare routine? If so, let me know which products you’ve seen amazing results with?
