Complete Guide to Vitamin A in Skincare
Vitamin A is one of the most celebrated yet often misunderstood skincare ingredients. Renowned for its ability to smooth fine lines, improve skin texture, fade dark spots, and combat acne, it’s a powerhouse in many skincare routines. However, its reputation for causing irritation and potential barrier damage often leaves people confused about how to use it effectively. Osmosis’ Vitamin A Serums stand out by using Retinaldehyde, a gentler yet highly effective form of vitamin A, in their formulations. This innovative approach delivers all the transformative benefits of vitamin A while minimizing the risk of irritation. Keep reading to discover how vitamin A can elevate your skincare routine, explore the different forms of this potent ingredient, and find out which Osmosis Retinaldehyde serum is the perfect match for your skin’s needs.
WHAT DOES VITAMIN A DO FOR THE SKIN?
Vitamin A in skincare has the ability to reprogram how cells function, influencing them to behave in a younger, healthier way for a radiant glow. It also helps with problematic skin conditions like acne by normalizing oil production, and pigmentation by regulating tyrosinase (an enzyme that plays an important role in the production of melanin). Vitamin A speeds up the skin’s natural exfoliation process - restructuring the skin from the ground up. It helps smooth fine lines, target pigmentation, keep pores clear, and
supports collagen.
Beta Carotene converts into Retinol, Retinol into Retinaldehyde and Retinaldehyde into Retinoic Acid. All of these vitamin A derivatives contribute to your skin health, but the struggle is to formulate products with the ability to penetrate the top layer of skin so they can work, and that is what often causes the skin irritation that some people experience with some forms of Vitamin A.
A BREAKDOWN OF KEY RETINOIDS:
Retinoic acid: This is the prescription-strength retinoid, commonly known as Tretinoin, that you can get from your dermatologist. Retinoic acid is the active form of vitamin A that directly binds to your skin's retinoid receptors and starts working immediately. Unlike other forms, it doesn’t require any conversions to be effective. While it’s highly potent, the downside is that it can often cause irritation, flaking, or stinging after just a few uses.
Retinol: This is the form of vitamin A that most people are familiar with. Retinol is effective but requires two conversions in the skin before it becomes the active retinoic acid that your skin can use. First, it converts to retinal, and then to retinoic acid. Because of this extra conversion process, it tends to work more slowly than retinal or retinoic acid, but it’s still a popular option for improving skin tone, texture, fine lines, and more. It’s a great starting point for those new to retinoids, as it’s typically less irritating than prescription-strength options. For skincare it is typically obtained from animal-derived sources. It is synthesized through chemical processes that convert natural sources of vitamin A, such as animal liver, into retinol. Alternatively, retinol can also be produced synthetically in a laboratory setting.
Retinyl Esters: Retinyl esters, such as retinyl palmitate, are the gentlest and weakest form of vitamin A. They must go through three conversions in the skin to transform into retinoic acid, which is why they’re less potent. This makes them a good choice for people with sensitive skin or for those looking for a very mild introduction to vitamin A. However, the tradeoff is that they deliver the slowest and least dramatic results.
Retinal (Retinaldrhyde): Retinal is the most powerful vitamin A derivative available without a prescription. It’s up to 10 times more bioavailable than retinol, meaning it works faster and requires a smaller amount to deliver noticeable results. The reason? Retinal only needs to undergo one conversion in the skin to transform into retinoic acid. In comparison, retinol requires two conversions to become active. This makes retinal an excellent option for addressing skin concerns like uneven tone, rough texture, fine lines, wrinkles, and loss of firmness.
Pro tip: a high-quality retinal product should have a bright yellow hue—this indicates its purity and potency. Retinaldehyde is typically derived from plant-based sources such as beta-carotene found in carrots, sweet potatoes and other fruits and vegetables.
So, why aren’t there more retinal products on the market? It’s notoriously tricky to formulate. Creating a product that’s effective, stable, non-irritating, and enjoyable to use takes advanced expertise. Plus, due to its potency, retinal is a more expensive ingredient to include in formulations compared to other retinoids. However, its benefits make it a standout option for those seeking impactful results without a prescription. Osmosis Retinal serums are more bioavailable, meaning they absorb faster and more thoroughly, making them clinically-proven to work 11 times faster than Retinol.
