What Active Ingredients Should I Include in my Skincare Routine?

Powerful ingredients are essential for skincare that makes a difference. With various product options available, it is crucial to know which ingredients will work best for your skin type and how they may affect your skin. Whether your face is primarily oily, dry, dehydrated, or a combination of these, a simple and tailored skin care routine can significantly improve and enrich your skin for a clearer and brighter complexion. Here are some essential active ingredients to look out for in your skincare products:

Vitamin A

Vitamin A is the gold standard in cosmeceuticals. This fat-soluble vitamin is scientifically proven to increase cellular turnover, stimulate collagen production and enhance youthful gene expression. This ingredient allows old dead cells to be replaced with younger, healthier skin. While it may take up to 12 weeks to truly see the difference, the results are transformative. Beyond minimising enlarged pores and tackling the effects of sun damage, vitamin A also helps to reduce pigmentation and inflammation of the skin, simultaneously smoothening fine lines on the face. The ingredient even actively helps to regulate oil production, making it highly beneficial for fighting acne. Active forms of vitamin A include retinol and retinoic acid, so look out for formulas with these ingredients. However, the type of retinol and retinoic acid used in formulations matters: most retinols are unstable when exposed to air and heat, reducing their effectiveness once a product has been opened.

It is important to note that some skin types can react harshly to vitamin A at first, which may lead to skin irritation, flakiness or redness. The key is to start at lower concentrations so your cells can adapt and better tolerate the ingredient.

How to Use Vitamin A

Australian skincare brand Synergie boasts a product range imbued with a stabilised form of retinol, allowing for deeper penetration and greater product longevity yet minimal skin irritation. Rather than significantly degrading over time, the effectiveness of their stabilised retinol remains constant. In vivo clinical studies of their stabilized retinol show a reduction of visible wrinkles in 4 weeks of application. The product should be applied at night, every third night for a week; after which, the product should be used every second night for a week, and then every night for the following weeks. This process should help to avoid aggravating the skin.

Upon application, your skin should be clean and dry, only a pea-sized amount should be used, and your eye and lip area should be avoided. If you experience irritation, lessen the frequency of use until this has been resolved. Once the redness dissolves, you can slowly increase the frequency of use until the skin tolerates it well.

Vitamin A should not be used by pregnant women, breastfeeding mothers, or by those planning on becoming pregnant. When using vitamin A, it is also recommended that you apply sunscreen daily to reduce sun sensitivity.

Vitamin B

Vitamin B is a highly valuable ingredient in skin care. Niacinamide, a form of vitamin B3, actively penetrates the outermost layer of the skin (stratum corneum) to allow for significant results. This ingredient has anti-inflammatory properties, which helps to improve the skin barrier, reduce skin sensitivity, prevent UV damage and ease irritation. Its hydrating qualities also serve to reduce transepidermal water loss, which allows the skin to maintain higher levels of hydration and moisturisation, preserving its fresh and bright tone. For those suffering from sensitive or dehydrated skin, this ingredient is key to making your skin more resilient to environmental aggressors, including pollution, everyday chemical elements and sunlight, reducing redness and inflammation.

Vitamin B also boasts anti-ageing properties, stimulating collagen synthesis and improving the appearance of lines and wrinkles to produce a smoother, more youthful complexion. This ingredient is also helpful for treating pigmentation and fighting acne, as it reduces oil production and alleviates acne-related inflammation.

How to Use Vitamin B

Vitamin B may break down in highly acidic environments, particularly in reaction to nicotinic acid, so it is important to avoid mixing this directly with AHAs, BHAs and vitamin C to prevent irritation. However, vitamin B improves the skin’s capacity to tolerate retinol (vitamin A) and is ideally used in combination. While the majority of skincare brands use 5% of vitamin B, Synergie’s products have a concentration of up to 15%, boasting a higher capacity to heal and enrich the skin.

Vitamin C

L-ascorbic acid is the only form of vitamin C that can be used on the body: it is highly active and thoroughly penetrates the skin. The ingredient is high in antioxidants, which serves to prevent cell damage and premature ageing, while its protective properties defend against sun damage by neutralising free radicals beneath the skin. The L-ascorbic acid helps to reduce inflammation and treat pigmentation, while the ingredient’s stimulation of collagen production helps to minimise fine lines and wrinkles. Additionally, this vitamin C form is commonly used in skincare products because of its ability to regenerate vitamin E, as well as its capacity to accelerate healing.

How to Use Vitamin C

The most common sources of intake of L-ascorbic acid are topical application and dietary intake. When using vitamin C products, it is recommended that usage is increased gradually to allow time for the skin to adapt, since the ingredient is highly active. Synergie’s vitamin C products are carefully blended with acids that work in combination to boost skin for a youthful and radiant glow. Synergie’s unique mixtures target various areas and concerns associated with the face, from addressing skin dryness, uneven tones and signs of pigmentation, to hydrating and reviving dull skin. When using the product, it is recommended to follow application with adequate sun protection.

Vitamin E

Vitamin E is a fat-soluble ingredient that helps to support and preserve skin health. As an antioxidant, vitamin E helps to protect the skin from the effects of free radicals produced by toxins in the environment. Its anti-inflammatory properties serve to defend against sun damage by absorbing the energy from UV light, which helps to prevent the formation of wrinkles, creases or sagging in areas of the face. Vitamin E is also used to reduce the symptoms of atopic dermatitis and often works well with vitamin C to strengthen cell walls.

How to Use Vitamin E

Vitamin E absorbs easily into the skin. It is used in various skincare products, including anti-ageing creams, sunscreens, eye serums and make-up, and can help to increase the amount of vitamin E stored within the sebaceous glands. The ingredient has been scientifically proven to reduce acute and chronic sun damage caused by UV irradiation. It can also make for an excellent moisturiser for dry and patchy areas of skin, such as the cuticles and elbows. Synergie blends vitamin E with other essential ingredients, such as zinc, to maintain youthful and smooth skin and neutralise oxygen free radicals. When combined with the right elements, vitamin E can defend against premature ageing and provides gentle protection and hydration for body areas regularly exposed to UV light.


Zinc is a highly sought ingredient in skincare products. Its anti-inflammatory and non-irritating properties make it ideal for sensitive skin and may help to relieve some of the redness, irritation or scarring associated with acne, rosacea, eczema and seborrheic dermatitis. Zinc is one of the most widely studied forms of acne treatment and has also been used for other inflammatory skin conditions, such as melasma, rosacea, eczema and. More importantly, a compound of Zinc called Zinc Oxide is one of the best sunscreen ingredients available. Not only is it effective at providing broad spectrum UVA and UVB protection, it is also non-irritating for all skin types and non-comedogenic, meaning it will not clog pores.

How to Use Zinc

Zinc is a versatile ingredient used in many skincare products. Synergie blends zinc with other essential ingredients, such as vitamin E and green tea extract, to create anti-ageing formulas that also hydrate and protect the skin. The ingredient is used in products for sensitive skin, particularly following clinical treatments. Synergie’s UberZinc is our recommended moisturiser with sun protection. The best part: It’s also reef-safe. Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs) It is crucial to include gentle chemical exfoliants like AHAs and BHAs in your skincare routine. Not only do they provide a no-downtime resurfacing effect and clear away unwanted dead skin cells, they also enhance the penetration of other active ingredients for better results.

Whether you’re looking to smooth away the look of fine lines and wrinkles, or remove the impurities causing breakouts, formulations with these ingredients can help. AHAs are water-soluble, and include Glycolic acid, Lactic acid and Malic acid, some of which are also powerful antioxidants. They break the bonds that hold surface skin cells in place, preventing them from being trapped in the pores. They also encourage the creation of new collagen by increasing cellular turnover for a firming effect over time.

BHAs on the other hand are oil-soluble, and include Salicylic acid, derived from white willow bark. This anti-bacterial, anti-fungal and anti-inflammatory ingredient is able to penetrate pores and cut through the oil clogs that result in whiteheads and blackheads. Effective for managing the symptoms of folliculitis, psoriasis and rosacea, it can also help fade the hyper-pigmentation left over from old breakouts.

How to Use AHAs and BHAs

AHAs and BHAs can be used together as their effects are complementary, and they can both be found in formulations like Synergie’s Exfol X and Reveal exfoliating serums or Decongest and Blem-X blemish control serums. Depending on your skin’s needs, these products be applied a few times weekly (For normal skin) to daily (For congested, acne prone skin). It is important not to use these acids at the exact same time as vitamins A or B as they can causes these particular ingredients to be less effective. A good routine would stagger these products, so once set is used during the day, and another at night for maximum benefits. It is imperative to apply sufficient sun protection when using these products, as the healthy new skin cells are at greater risk of damage without adequate sunscreen.

Hyaluronic Acid

Think of this as a refreshing drink for your skin. A type of sugar, Hyaluronic acid is famously able to hold 1000 times its weight in water, providing serious skin hydrating and plumping properties. It’s naturally produced by our own skin cells to maintain moisture levels, but our ability to do so can be degraded over time and through UV exposure, resulting in loss of skin elasticity. It works for any skin type as well, including sensitive or acne-prone skin, and even those with oily complexions.

How to Use Hyaluronic Acid

Soothing and smoothing, when topically applied Hyaluronic acid is an excellent way to maintain skin hydration and prevent the loss of moisture. It can be found in the Synergie Skin Hydrogel, a lightweight oil-free moisturiser, as well as the ImprovEyes eye serum. Apply a generous amount to cleansed skin for a moisture barrier that can last all day.

What Ingredients Should I Avoid in my Skincare Routine?

When establishing a healthy skincare routine, it is crucial to avoid ingredients that may harm or irritate the skin. The key is to be aware of these ingredients when shopping for products and to seek instead those that are rich in natural components, antioxidants and protective properties. Some of the ingredients you should avoid include:

  • Dimethicone and other silicone ingredients are often used to create a silky smooth texture for that “gliding” effect of a product on your skin. However, the same coating action prevents the skin from performing its usual activities including sloughing off dead skin cells. It also traps bacteria, impurities and sebum, which can lead to an increase in acne. Long-term exposure to this non-biodegradable ingredient can also lead to an increase in skin sensitivity as it is a potential irritant.
  • Talc, which is often used as a cheap bulking agent for pressed or powdered products, is used to produce soft, absorbent skin. However, it may contain traces of lead which could pose health risks.
  • Mineral oil or petrolatum gives the illusion of moisturising due to its oily and occlusive nature. However, this ingredient may clog the pores and impair natural skin processes, such as cell turnover, nutrient absorption and toxin release. Possible contaminants from petroleum refining may also irritate the skin.
  • Artificial colour is used merely for appearance and provides pigment to make-up and skin care. However, this ingredient has no functional benefits and may contain traces of lead and other toxic heavy metals. It is also a common cause of skin irritation.
  • Artificial fragrance also has no functional benefit and is a common cause of allergy, sensitivity and skin irritation.
  • Parabens and other artificial preservatives are useful for preventing the growth of bacteria and mould in skincare products, but they are also closely linked to skin irritation and allergic reactions.
