Once applied, Coco-Caprylate/Caprate is absorbed quickly and leaves a silky feel.

Coco-Caprylate/Caprate may not be fungal acne safe.

Tocopheryl Acetate is commonly found in both skincare and dietary supplements.

First, Retinyl palmitate is created from palmitic acid and retinol. It is a retinol ester and considered one of the weaker forms of retinoid.

This is because all retinoids have to be converted to Tretinoin, AKA retinoic acid. Retinyl Palmitate is pretty far down the line and has to go through multiple conversions before its effects are seen.

Due to this long and ineffective conversion line, the benefits of Retinyl Palmitate are debated.

Studies show Retinyl Palmitate to help:

Dermatologists say this ingredient is ineffective because it isn't used in high enough concentrations in cosmetics.

This ingredient used to be found in sunscreens to boost the efficacy of sunscreen filters.

The downfall of Retinyl Palmitate was due to released reports about the ingredient being correlated to sun damage and skin tumors.

While there is a study showing this ingredient to cause DNA damage when exposed to UV-A, there is no concrete proof of it being linked to skin cancer. It is safe to use when used correctly.

All retinoids increase your skin's sensitivity to the sun in the first few months of usage. Be especially careful with reapplying sunscreen when using any form of retinoid.

Currently, this ingredient is still allowed in cosmetics all over the world. In Canada, cosmetics must have a warning label stating the product to contain Retinyl Palmitate

Fun fact: This ingredient is often added to low-fat milk to increase the levels of Vitamin A.

Studies show dimethyl isosorbide is able to penetrate skin to deliver other ingredients into the skin, making them more effective.

Retinoids have been proven to:

So what is the difference between all the retinoids? Most retinoids need to go through a conversion line to become effective on skin. The ending product is retinoic acid. Retinoic acid is AKA tretinoin.

HPR is an ester of tretinoin. Emerging studies suggest HPR to have an added benefit that other retinoids don't have: Low irritation.

A study from 2021 found HPR to have the greatest stability when exposed to light and temperature out of all the commercial retinoids.

A note about naming: The name "Granactive" is the trade name and the name most commonly used on packages.

Granactive is the name of the mixture - about 90% solvent and 10% HPR. A product with 5% granactive has 0.5% HPR.

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.
