Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Timeless Skin Care 20% Vitamin C + E Ferulic Acid Serum contains this as ingredient number 1.
Ascorbic Acid is is pure Vitamin C. This form makes up the largest amount of vitamin C found naturally in our skin.
Not only is vitamin C great for your overall health and immune system, it also has plenty of benefits on your skin.
Vitamin C is best used for brightening skin. It improves dark spots, acne scars, and hyperpigmentation. This is because it blocks the process of skin darkening when exposed to UV.
Remember: Vitamin C should not replace sunscreen!
Your skin uses vitamin C to build collagen. Collagen is one key component in having a strong skin barrier and plump skin. Vitamin C also plays a role in regulating collagen, thus making it effective in improving wrinkles and fine lines.
Ascorbic acid shows potent antioxidant activity. As an antioxidant, it helps fight free-radicals. Free-radicals are molecules that may damage your skin cells. These antioxidants also protect skin against UV damage.
The best formulations include Vitamin E and/or ferulic acid. These two ingredients help stabilize and provide a boost in the benefits of ascorbic acid. This is because ascorbic acid becomes unstable when exposed to UV and air. In fact, you can tell your ascorbic acid has oxidized when it turns an orange-yellow color.
Ascorbic acid is generally compatible with other ingredients. However, using ascorbic acid with other active ingredients might cause irritation. Two ingredients: copper ions and benzoyl peroxide, will inactivate ascorbic acid completely.
Read more about other types of Vitamin C:
Foods rich with vitamin C include oranges, strawberries, broccoli, bell peppers, and more. When consuming Vitamin C, your skin receives a portion of the nutrients.

Timeless Skin Care 20% Vitamin C + E Ferulic Acid Serum contains this as ingredient number 3.
Ferulic Acid is a plant based antioxidant. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells. Ferulic Acid can help reduce the formation of fine lines and hyperpigmentation.
When used with Vitamin C, Ferulic Acid has shown to prevent Vitamin C from breaking down. In other words, it acts as a stabilizer.
Ferulic Acid is sometimes used to preserve food. Foods containing Ferulic Acid include: oats, rice, eggplant, citrus.
In medicine, Ferulic Acid is being studied for helping with diabetes, Alzheimer's, and cardiovascular diseases.

Timeless Skin Care 20% Vitamin C + E Ferulic Acid Serum contains this as ingredient number 8.
Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Great price, great ingredients, fresh. I notice the effects in my skin. Big but not for sensitive skin. I am an stubborn girl so I made it work. For a long time my morning routine was this and a lot of Centella and oat and hidrating essences just to stop my skin from reacting. Now I can use it without worrying but I need a calming essence immediately after it.
Love this C serum. Easy to apply, great price and a great company.

I've tried about 5 different Vitamin C serums, and this one is by far my favorite. I've purchased it 3 times. (I started using it back when it was the dropper bottle)
My skin can tolerate higher Vit C percentages very well, so this feels like nothing on my skin. As if I was putting on water. I don't mind the ferulic acid smell (which is noticeably less now than it used to be!), because I think having it in the formula is more important than not.
Even in the new opaque pump top packaging, the product will still oxidize rather quickly - so don't be afraid to use it! Use it daily, use it on your neck, your chest, your arms. Use it up before it turns orange!
I see results when using this very fast. Stubborn cystic acne clears up within a week. Old red acne marks fade faster. Freckles and pigmentation lighten dramatically within a few weeks. And it prevents new acne. I really do see results and this is one of the quickest and friendliest products/ingredients to do that for me!
Downsides:
- it still oxidizes rather fast. So, like I said, use use use it up.
- I prefer the old dropper bottle packaging, I need about 2-3 pumps for my face, and another 2 for my neck/decolletage. I also do not like not being able to see how much product is inside.
- the formula in the newer packaging feels a little more ...watery than before? I can't help but feel like most of the product stays on my hands and doesn't get transferred adequately to my face.
- I had a bad cross reaction with this product and The Ordinary Niacinamide 10% serum. I don't care what the internet says - I learned the hard way that Vit C and Niacinamide DO interact with each other. I now keep the Vit C for the morning and Niacinamide for the evening. But whew boy, that was painful.
Overall I really love the higher % of Vit C plus the Ferulic Acid combo, and this is the best serum I've tried that my skin likes, that I can see works, and is affordable.
Love it, absorbs fully and quickly, helps with overall even tone.
