Why is retinol famous?
It has the most scientific studies backing up its skin benefits out of all the non-prescription ingredients.
Retinol is proven to:
This is why retinol is effective at removing wrinkles, fading dark spots, treating acne, and reducing the appearance of pores.
Studies show retinol is less effective when exposed to UV. Be sure to look for appropriate packaging to keep your retinol potent (similar to Vitamin C).
Using retinol or any retinoids will increase sun-sensitivity in the first few months. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.
We recommend speaking with a medical professional about using this ingredient during pregnancy.
Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.

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 retinol for beginners
This is a product with a low dose of retinol, which makes the product suited to apply in the eye area as well. A lot of my earlier products containing retinol were serums, while this is more of a cream. It makes it more hydrating, but without an additional moisturiser it is still drying me out.
Although the percentage of retinol is low, your skin has to adjust to the retinol, using it every other day. Combining it with a moisturiser and a good hydration serum in the morning makes this a great product for your skin.
I highly recommend combining this with Missha Time Revolution Night Repair. It did wonders for my skin!

Broke me out
I have oily and acne prone skin and my face was on the road to recovery. I thought adding a retinol was a good idea and they marketed that this retinol oil is good for any skin type even though it is oily. It broke me out and gave me a scar within a week. It gave me an acne that was deep inside of my skin. I wouldnt recommend it to oily and acne prone skin people.
