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. If you see this, drink a glass of water. Stay hydrated!
Learn more about Water1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.Â
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservativesÂ
Trehalose is a disaccharide made of two glucose molecules (glucose is sugar!). Trehalose is used to help moisturize skin. It also has antioxidant properties.
As a humectant, trehalose helps draw moisture from the air to your skin. This helps keep your skin hydrated.
Due to its antioxidant properties, trehalose may help with signs of aging. Antioxidants help fight free-radical molecules, unstable molecules that may damage your skin.
In medicine, trehalose and hyaluronic acid are used to help treat dry eyes.
Some animals, plants, and bacteria create trehalose as a source of energy to survive freeze or lack of water.
Learn more about TrehaloseAllantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Some studies have shown this ingredient can promote wound healing with higher concentrations.
Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.
Learn more about AllantoinEthylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
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.

HG acne scar serum
Initially, this serum had helped fade away most of my old acne scars. After while, I thought it didn't do anything more for my new acne growth. So I ditched this serum for about 3 months and tried other new niacinamide products. I REGRET it. Soon after, I got more and more whiteheads and acne. My skin texture becomes uneven and dry. The new acne scars couldn't fade away at all. Show more

Wonderful beginner retinol
Ny first ever retinol but 2nd time using a retinoid. for context I have highly acne-prone skin.
I've been using this every other night for a couple weeks now and I see that my acne is healing much faster than usual, i.e. less redness and irritation on acne that I would usually experience.
Though there are ingredients rated by SkinSort as not good for acne-prone Show more
(Started Dec 2023) This was a bit of an impulse buy with a friend, but I'm honestly glad I got it! I have previous experience with using retinoids (specifically from The Ordinary Line) and wanted to try something a bit stronger. On Amazon it is priced at $13, so I would say this is a wonderful budget buy. The formulation is very gentle given the strength and I experienced no problems with Show more
