Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

1
What it does: Skin Conditioning, Solvent
Community Rating: Loved

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!

2
What it does: Skin Conditioning
Community Rating: Loved

Panthenol (also referred to as pro-vitamin B5) is a common ingredient that helps hydrate and soothe the skin.

lt is a humectant, meaning that it helps the skin attract and retain moisture.

Another benefit is the anti-inflammatory abilities. This means that it's great for sensitive, irritation-prone skin.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

Timeless Skin Care 20% Vitamin C + E Ferulic Acid Serum contains this as ingredient number 7.

3
What it does: Antioxidant, Masking, Skin Conditioning
Community Rating: Liked

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.

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.
