Over time, skin naturally experiences a gradual decline in collagen, elastin, and hydration levels. Environmental factors such as sun exposure, pollution, and stress can further contribute to skin damage through free radical formation. The abundance of skincare ingredients available today can make it difficult to identify those that effectively contribute to high-quality skincare formulations.
Hyaluronic acid is a natural ingredient, composed of repeating units of the disaccharide D-glucuronic acid and N-acetyl-D-glucosamine, forming a large chain of sugar molecules. It is found throughout the entire body, primarily in the skin, eyes, and synovial fluid that lubricates the joints.
Hyaluronic acid keeps the skin supple and hydrated, giving it that dewy, glowy effect. That is because this molecule can hold 1000 times its weight in water. This humectant property is achieved by pulling water from the air and deep layers of the skin, providing a youthful appearance and filling fine lines that could appear due to dehydration.
With age, the body loses hyaluronic acid naturally, so the skin becomes dehydrated more easily. Therefore, topical supplementation is most needed. The best part is that this skincare ingredient fits every skin type with no side effects.
Hyaluronic acid delivers what it promises: a boost of hydration. Additionally, it pairs well with other active skincare ingredients, and it benefits any skin type at any age. Those people with dry or mature skin will benefit the most from using hyaluronic acid-based cosmetics.
In general, hyaluronic acid is known for being non-irritating because it is a molecule naturally produced in the body. Also, it won't trigger any acne or rosacea reactions. Hyaluronic acid increases the permeability of the skin, making it easier for other products to be absorbed into the skin's surface. But it also means that this ingredient should be combined with a moisturizer to draw more water to the skin.
The terms "Retinol" and "Retinoids" are often used interchangeably without much thought. However, this can lead to a significant misunderstanding because Retinol has become a crucial component in anti-aging skincare. Unfortunately, many people are unaware of what it actually is or are confused by the various types and percentages available.
To begin with, let's make clear that Retinol is one specific type of retinoid—the most popular one. On the other hand, retinoids is a blanket term that encircles the entire FAMILY of vitamin A derivatives, including from weaker to strongest:
Retinol esters
Retinol
Retinaldehyde (Retinal)
Tretinoin (aka Retin-A)
Isotretinoin,(aka Accutane), is a prescription retinoid that you take orally.
Though it might be a bit confusing, it is important to understand how retinoids convert to the active form of vitamin A, also known as retinoic acid. Retinoids, including retinol and retinaldehyde, undergo enzymatic conversion in the skin to become retinoic acid. This molecule is the one that binds to the retinoid receptors in the body, particularly in the skin, where it accelerates cellular renewal and repair.
By promoting the turnover of skin cells and enhancing collagen production, retinoic acid helps to reduce the appearance of fine lines, wrinkles, and hyperpigmentation, leading to a more youthful and even-toned complexion.
This is how retinoids improve fine lines and wrinkles, fade hyperpigmentation, improve skin elasticity, and eliminate skin texture. Whichever retinoid you choose, it will be a truly powerful multitasker in your formulation.
No matter which retinoid you apply to your skincare product, the cells can only use the active or 'bio-available' form of vitamin A (retinoic acid). The strongest retinoids (prescribed forms), tretinoin and isotretinoin, are pure retinoic acid.
Conversely, gentler, over-the-counter retinoids like retinol first have to be converted into retinoic acid by the enzymes in our skin before they can actually work. The more effective (potent) retinoids are closer to retinoic acid. Thereby need fewer conversions, so to speak.
Retinol, the most popular over-the-counter retinoid, needs to go through two conversions before it becomes active. It is about 10 to 20 times less potent than retinoic acid. Retinol comes in multiple percentages, being the most used 0.25%, 0.5%, 1%, and 2%. Percentage equals strength, and this means that although it can be more effective, it can also be more irritating.
Use it properly, and retinol can do wonders for your skincare products. Retinol CB 50, an innovative retinol formulation, is one of the most potent skincare ingredients that help boost cell turnover and combat the signs of aging. It effectively evens out skin tone and fades age spots. Also, Retinol CB 50 can help with cystic acne and blemishes.
Indeed, retinol is a highly effective skincare ingredient, but it is important to handle it with caution. It is always advisable to take a gentle approach when incorporating retinol into your skincare formulations.
To minimize or avoid redness, peeling, and dryness, it is recommended that consumers apply the product once a week for a month. For those with oily skin types, a higher percentage of retinol can be formulated. However, it is important to emphasize that clients should introduce it slowly and apply it once a week.
For the best possible results, it is recommended to wait at least 30 minutes before applying any other skincare products. Additionally, it is advised to use a small amount, about the size of a pea, for the entire face area.
The consistency or presentation of the product can have a crucial role in the performance and final strength. For example, serums are easily absorbed because they are lighter than creams. However, a cream-based retinol product could be ideal for dry skin types. It delivers the active ingredients slowly while offering a much-needed extra hydration boost.
For individuals with highly sensitive skin, formulations containing retinyl palmitate (a retinol ester) or low percentages of retinol have demonstrated effectiveness.
While their individual benefits are noteworthy, the true power of hyaluronic acid and retinol lies in their ability to work together synergistically. Instead of competing, these two ingredients complement each other, offering a comprehensive approach to address various skin concerns.
Hyaluronic acid, renowned for its exceptional humectant properties, deeply hydrates the skin, replenishing moisture levels and promoting a plump, flexible complexion. Meanwhile, retinol, a derivative of vitamin A, stimulates collagen production, encouraging skin renewal and addressing fine lines, wrinkles, and uneven texture.
This dynamic duo not only delivers individual benefits but also enhances each other's effects. Hyaluronic acid's hydrating properties can help mitigate the potential dryness or irritation sometimes associated with retinol use, making it a valuable addition for those with sensitive skin.
By incorporating both hyaluronic acid and retinol into a skincare regimen, individuals can experience a more comprehensive approach to skin rejuvenation, achieving a smoother, more radiant complexion.
Understanding the function of each ingredient and recognizing its scientifically supported advantages is not only crucial for developing high-quality skincare products but also for creating a personalized skincare routine that caters to individual needs and concerns.
By harnessing the unique benefits of each ingredient and combining them strategically, you can create a skincare product routine that addresses individual concerns and promotes healthy, radiant skin. So, whether it is the hydrating properties of hyaluronic acid or the anti-aging effects of retinol, embracing the power of both will lead to optimal results.
