Natural Ingredients: When Nature and Technology Collide

What's better for skin, natural ingredients or chemicals?  Wait—that's a trick question. Have you ever heard of "dihydrogen monoxide"? Sounds like an intimidating chemical, but it's just a fancy term for regular water, H2O. In fact, every substance is made of chemicals—even plants! That's because any chemical is made up of atoms and molecules, which can occur naturally or can also be synthesized artificially.

So, without using the word "chemicals," a better question might be:  "What's better for skin, natural ingredients or synthetic ingredients?"  In terms of skin care products, "natural ingredients" are derived from flowers, leaves, roots, bark, marine sources, soil (clay), minerals, and so forth. On the other hand, synthetic ingredients are created in a lab, and are often categorized as "cosmeceuticals."

However, in these days of advanced skincare technology, there's really no need to just have the two choices, as if they were polar opposites. In fact, natural ingredients are often the very source of cosmeceuticals, and in turn, cosmeceuticals can help promote, deliver, and even magnify the effects of natural ingredients.   

In this day of technology, there is now a third choice: a symbiotic hybrid of natural ingredients that are married to scientific advancements, with the goal of amplifying and enhancing skin care. By using microencapsulation, plant stem cells, and plant-derived cosmeceutical ingredients, formulators are redefining the role of "natural ingredients" in skin care.




Skin care formulators face many challenges when working with natural ingredients, such as concentration, stability, and delivery.

Challenge #1: Concentration. Some plant extracts would need to be applied in large quantities to provide the desired result. On the other hand, certain essential oils can be irritating to the skin when applied topically. In fact, just because an ingredient is identified as natural, doesn't necessarily mean it's well suited for the skin or will prevent allergic complications.

Challenge #2: Stability. When separated and isolated from their natural source, natural actives can undergo stability issues due to sensitivity to light, oxidation, temperature, and pH levels. The molecules break down and lose potency, which reduces or even destroys their effectiveness.  For example, vitamin C extracted from a natural source is known for reducing melanin production, fading hyperpigmentation, inhibiting free radicals, and boosting collagen. However, when exposed to light and air, some forms of vitamin C oxidize, lose efficacy and may even damage proteins and DNA.

Challenge #3: Delivery. The smaller the molecule, the more easily it is absorbed by skin, but larger molecules need a vehicle to allow them to pass through the stratum corneum. Water-soluble ingredients can't effectively penetrate skin's lipid layer, and oil-soluble ingredients might be too large or too unstable to pass through.

The good news: Many natural moisture factors and antioxidants stay on the top layer of the skin to soothe, hydrate, plump, and maintain the moisture barrier. The bad news: Without effective concentration, stability, or delivery system, many natural ingredients won't effectively penetrate skin's protective barrier.

Solution: Natural ingredients and cosmeceuticals don't have to battle it out when they can work in perfect harmony. The science of encapsulation technology can be married to the power of natural ingredients.



Like shuttles that deliver people to their destination on time without losing their luggage, microencapsulated natural ingredients 1) reach the targeted location, 2) do not lose their potency, 3) are released in a timely manner. So how does encapsulation impact natural ingredients and the skin?  The stratum corneum, the top layer of skin, is a barrier protecting the body from bacteria, environmental damage, and moisture loss. Microencapsulation technology allows natural ingredients to be absorbed through that protective layer. It begins with an outside shell material ("encapsulant") that prevents the natural active ("core") from getting out before it reaches the targeted area, and blocks other material from getting inside. Commonly used encapsulation substances include wheat proteins, soy, natural lipids such as phospholipids, liposomes, or beeswax, and polysaccharides like carrageenan from algae and chitosan from sea crustacean shells.

For example, vegetable-derived liposomes function as water soluble and oil-soluble carriers that easily pass through the stratum corneum. These microspheres smuggle in natural actives that are hydrophilic (water soluble) as well as actives that are lipophilic (oil soluble). Once absorbed, the skin is sealed with a micro-thin, flexible film to reduce transepidermal water loss (TEWL), dehydration, or the evaporation of moisture within skin. 

En route to the targeted site, the shell material prevents the active ingredient from degrading due to exposure to light or air, which maintains the ingredient's stability and efficacy. The core is released when there is a particular trigger, such as heat, pH, moisture, enzymes, diffusion, or dissolution. With a controlled release over time, the natural active is delivered to targeted areas at its full potential to provide anti-inflammatory and anti-aging skin benefits. This type of delivery system has an extremely low potential of skin irritation as the active targets wrinkles, hyperpigmentation, atopic skin, rosacea, post-treatment skin, wound sites, and other skin issues.



Many of the most potent natural ingredients depend on microencapsulation to provide skin renewing and healing benefits, and in a particular, the growing advancements in plant stem cell technology. Stem cells are essential for skin renewal. They work best with growth factors, which signal stem cells to renew collagen, elastin, and epithelial cells at targeted locations. Like human stem cells, plant stem cells are undifferentiated cells that divide to create the same type of stem cells or become specialized cells. They function as a cellular repair system, continuously dividing and replenishing other cells.

  Plant-derived stem cells have strong antioxidant and anti-inflammatory benefits and are used in skin care formulations that provide potential anti-wrinkle, antioxidant, and anti-aging benefits. Plant stem cells aren't just extracted from vegetation or fruit and dropped into skincare. Instead, they are cultured in labs where scientists and formulators have more control over the purity and quantity of the anti-aging substance produced by the plant, away from contaminants like pollution or pesticides. Antioxidants and other nutrients in the stem cells of the plant can therefore be more powerful when cultured in the lab for use in skin care products.

Harvesting for plant stem cells does not destroy the host plant. To obtain stem cells in the lab, the plant is slightly wounded by a small cut. The plant starts to heal itself by creating active substances that are non-programmed, "blank" cells with the potential to develop into various cell types performing different functions. A tiny bit of this tissue is extracted from the actively dividing cells of the host plant as it regenerates itself. Unlimited stem cells can then be cultured from the original, and their molecular potency can be multiplied by 1,000 times or more. The lab environment also ensures their purity, safety, and standardization. Best of all, researchers have found that when these stem cells are topically applied to skin, they help trigger renewal and even magnify the effects of antioxidants, vitamins, and minerals.

Still, these stem cells would need to be microencapsulated in order to be absorbed through the stratum corneum and deep into skin for anti-aging or repair benefits.



Plant stem cells are a logical source for anti-aging skin care, since plants have evolved sophisticated natural mechanisms for combating environment stress and harsh environments. Sources for plant stem cells include highly resistant flowers, plants, and fruits that survive and even thrive in extreme conditions. With high concentrations of antioxidants, plant stem cells help neutralize free radicals that cause photo damage and other signs of premature aging. Research supported by clinical trials has shown that plant stem cells help deliver moisture deep into skin, plump away wrinkles, minimize inflammation, boost collagen production, restore elasticity and firmness, and protect skin against damage from UVA and UVB rays. Stem cells from plants, flowers, fruits, and vegetables are cropping up in skin care formulations, where they are touted not only for their antioxidant benefits but are also used for the purpose of promoting skin renewal.

In the treatment room, exfoliation is essential. No matter how many skin-loving ingredients are put onto skin, they cannot interact with other molecules and cellular processes if dead skin cells, excess sebum, or makeup residue are in the way. The number one rule of helping product penetrate skin is to keep it exfoliated and hydrated.

Exfoliants like alpha and beta hydroxy acids derived from natural substances provide multiple skin benefits. Encapsulated in liposomes, they can be delivered into skin with a lowered chance of skin irritation. Look for exfoliants containing phospholipids or liposome carriers along with the appropriate hydroxy acid or natural fruit enzyme that suits the specific skin concern.

A plethora of natural cosmeceuticals can be used for different skin conditions and concerns in the treatment room. Keep in mind that natural ingredients aren't limited to plants and algae—they also include minerals and clays. In fact, whether encapsulated or not, some herbs, plants, clays, and algae contain a mother lode of skin-loving minerals, with benefits for each client's individual skin issue.

Plant science is growing. The burgeoning trends of plant stem cells, minerals, and even plant-derived peptides have firmly rooted themselves in skin care treatments. It's time for a different perspective on our expectations of using natural ingredients to improve skin structure and health. Technology married with the potential of botanical actives and therapeutic minerals can exponentially change the face of skin care. But is this hybrid the best solution?

That depends. Every client's skin is unique. The esthetician's first task is to determine the client's specific concerns in order to identify which ingredients and products would be most beneficial, and understand the reasoning behind those choices. In some cases, natural ingredients are not necessarily better. In fact, some herbal extracts may cause serious sensitivities for certain individuals. Just because it's natural doesn't mean it's automatically going to be non-irritating. On the other hand, even though some synthetic compounds like parabens and phthalates have been identified as potentially dangerous to overall health, not all bio-engineered ingredients are skin's enemy.

In these days of skin care technology, science can greatly enhance the power of natural ingredients. Formulators can lock the vitamin C molecule to make it stable. They can coat natural ingredients with natural liposomes to ensure efficacy. Microencapsulation allows multiple active ingredients to reach targeted areas and perform optimally. Airtight, opaque containers or airless pumps help prevent some ingredients from oxidizing when exposed to air or light. As technology bolsters the effects of plants and minerals, leading-edge research may push skin care decades ahead of where we are today.

Lastly, remind clients that healthy skin is not limited to topical elements. The foods they put into their bodies can definitely impact skin. It's not unusual for some skin conditions to become aggravated because of internal factors, like vitamin or mineral deficiencies. However, nutraceuticals, known as "functional foods," provide dietary vitamins, minerals, fatty acids, amino acids, and antioxidants. These systemic elements also affect the appearance of healthy, youthful-looking skin. Encourage clients to approach skin care from the inside-out as well as the outside-in.

Natural ingredients? Cosmeceuticals? We don't need to choose sides. Skin care doesn't need to be politicized if we take the best of both worlds in order to give a boost to each client's skin care results. Stay up-to-date, and ignite an awareness of the powerful fusion of the botanical and clinical worlds.
