Chances are you’ve heard that vitamin A is a key ingredient in skin care. Its remarkable ability to reverse aging, increase nutrients and encourage the production of collagen and elasticity in the skin is unmatched.
But with so many different forms of the vitamin A molecule, it can be difficult and overwhelming to figure out what is best for our skin.
In the body, we convert Beta Carotene into Retinol, Retinol into Retinaldehyde and Retinaldehyde into Retinoic Acid.
All of these vitamin A derivatives are important for your skin health, but because of the size of some of the derivative molecules, they struggle to penetrate the top layer of skin (epidermis) when applied topically. This can result in skin irritation and sun-sensitivity that some people experience with common forms of Vitamin A.
Difference Between Retinol and Retinaldehyde
You’ve probably seen the R words thrown around a lot while looking for information on Vitamin A for your skin. But what is the difference between Retinol and Retinaldehyde?
Research has shown that Retinaldehyde and Retinoic Acid are 500 times more active than their vitamin A counterparts (Beta Carotene and Retinol), meaning smaller amounts can be used and absorbed into the skin to achieve collagen stimulation and skin-smoothing results. And Retinaldehyde is gentler on your skin.
Why Retinaldehyde over Retinoic Acid? Retinoic Acid, when applied topically, can be irritating and cause over-exfoliation or shedding and can be very inflammatory.
Retinaldehyde, in addition to having its own receptor activity, is a smaller molecule than Retinol and is the immediate precursor of Retinoic Acid. The skin will convert Retinaldehyde to Retinoic Acid in the amount it needs for use and then stores the rest in adipose tissue for future use.
Retinaldehyde is not sun-sensitising so it doesn’t increase your risk of UVA/UVB damage or hyperpigmentation, unlike Retinol. Meaning you can include it in your daytime skincare program.
There are many retinaldehyde benefits but the ones below are some of our favourites.
- Promotes cell turnover
- Brightens skin tone
- Aids skin tightening
- Thickens your dermis (inner layer of your skin)
- Restores a youthful complexion without irritation
- Gentler on your skin compared to other Vitamin A
- Safe to use while your pregnant or breastfeeding
- Safe to use morning and night
Osmosis Products with Retinaldehyde
Now, let’s talk product penetration. The dermal layer of the skin is where the majority of aging occurs. It is critical that active ingredients deeply penetrate for visible results.
Using a smaller percentage of Retinaldehyde does assist with its journey into your skin, but we have taken that process a step further. Our unique liposomal delivery system ensures optimal results by coating the retinaldehyde molecule in a liposome called phosphatidylcholine to increase penetration by 600%. This coating mimics the properties of the cells in your body, making it easily recognizable by the skin and body to enhance absorption and boost results.
That is why we formulate our serums with Retinaldehyde coated with phosphatidylcholine.
