Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Squalane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.
Because squalane boosts hydration in the skin, it also comes with plenty of benefits: it is an antioxidant and can help fight free radicals and skin damage. Squalane is also found to have a detoxifying effect when applied.
Squalane comes from squalene, which occurs naturally within the sebum of our skin. It is one of the oils our skin produces to keep itself hydrated. Squalane is the hydrogenated version of squalene and has a longer shelf life.
Research shows that squalane is non-irritating (even at 100% concentration).
In general, it's a fantastic ingredient. It does a great job at hydrating the skin, and it's suitable for those with sensitive skin.
The source of squalane may impact malassezia / fungal acne. This is because olive oil derived squalane can contain impurities such as fatty acids and plant waxes. Sugarcane derived squalane is recommended for anyone with malassezia concerns.
Is squalane vegan?
This depends on the source. Squalane can be derived from both plants and animals. Most squalane used in skincare comes from plants.
Please note: the source of squalane is only known if disclosed by the brand. We recommend reaching out to the brand if you have any questions about their squalane.

Retinal is a form of retinoid. Retinoids are the gold-standard class of anti-aging ingredients.
Retinal has many benefits as other retinoids: improve skin texture, reduce large pores, reduce the effects of aging, reduce the visibility of dark spots, heal scars, and fight acne.
Studies show retinal may work at a faster rate than retinol due to its structure.
All retinoids have to be converted into retinoic acid before starting to work. Some retinoids take several steps of conversion before binding. Retinal is only one step away, making it more potent.
Like other retinoids, retinal may be irritating. It is best to ease into using this ingredient frequently.
Using the 'ramp up' method, start by using retinol once a week. This gives your skin time to adjust and decrease irritation. Once you feel ready, you can slowly increase the frequency of retinol use.
Using retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

HoliFrog Moonbeam Retinol Treatment Serum 31 ingredients
HoliFrog offers some great products, so I decided to try their retinol serum (2.5% encapsulated retinaldehyde). The formula is very gentle and didn't cause any irritation. However, unfortunately, it caused my skincare to pill when used with certain product combinations.

This product contains Retinaldehyde (Retinal) but a very low percentage so the results will take time to show. So far, a month and half of use, and I have avoided any irritation. I did follow the instructions on how to gradually introduce the product and I still have not gone beyond using it 3 to 4 times a week. Overall I am happy with it.
