Ingredient
Antioxidants
Vitamin C
What It Is

Vitamin C is an essential nutrient required for the growth and repair of tissues in all parts of the body, including the skin, but we cannot produce it on our own. The powerful antioxidant is found naturally in fruits and vegetables and commonly produced synthetically in skincare products, such as moisturisers, toners, and, most often, serums.

What It Does

How to use in your skincare routine?

Whether your skin is dry, oily, or a combination, vitamin C is beneficial for skin health, helping it look and feel healthier and younger longer.

Before you apply the vitamin C, test a patch of skin with a lower-concentration formula to see how your skin reacts. Some minor tingling is normal, but if you experience anything more intense, stop using the product and talk to your dermatologist.

For best results, apply this vitamin topically 1-2 times a day, morning and night. Be sure to apply a moisturiser with a broad-spectrum SPF after vitamin C application for daytime.

Benefits
  • Vitamin C makes sun damage and surface pigment spots less visible and brightens a dull, blotchy skin.
  • It is a powerful antioxidant that protects the skin from irritation, inflammation and environmental pollution.
  • It reduces red blotches left after spots by improving the skin’s natural healing process.
  • It increases the effectiveness of sunscreen and gives the skin better protection from UV rays 
Vitamin E
What It Is

Vitamin E is a fat-soluble, essential nutrient with anti-inflammatory properties. Vitamin E helps support the immune system, cell function, and skin health. It’s an antioxidant, making it effective at combating the effects of free radicals produced by the metabolism of food and toxins in the environment.

Vitamin E is a powerful antioxidant that may be effective at reducing UV damage in skin. And when applied topically may help nourish and protect your skin from damage caused by free radicals.

What It Does

How to use in your skincare routine?

It can be used underneath moisturiser and sunscreen in the morning [if it’s a vitamin E oil] and is sometimes combined with other antioxidants, such as Vitamin C in Serums.

Best suited for those with dry, very dry, or mature skin.

Avoid using if you have very oily, acne prone skin or those prone to sensitivity.

Benefits

In moisturisers it can:

  • Stop skin from losing moisture.
  • Protect cells from damage.
  • Soften skin.
Hyaluronic Acid
What It Is

Hyaluronic-acid a substance that retains moisture and is capable of binding over one thousand times its weight in water. This substance is naturally found in many areas of the human body, including the skin, eyes, and synovial fluid of the joints.

As we age, the production of key substances in the skin, including hyaluronic acid (along with collagen and elastin) decreases. As a result, our skin loses volume, hydration, and plumpness.

The substance works as a magnet for moisture, helping your cells retain as much of it as possible so that your skin feels and appears hydrated, plump and healthy.

What It Does

Moisturisers and serums are two of the most common form of hyaluronic acid.

  • Moisturisers. Use a moisturiser infused with hyaluronic acid at the time when you’d usually moisturise. Ideally, this would be 2 times a day and always after cleansing, exfoliating, or applying serums.
  • Serums. A hyaluronic acid serum involves a slightly different routine. After cleansing, use a toner on your skin and press a couple of drops of your serum into your face with the palms of your hands. Don’t forget to apply a moisturiser immediately afterward to seal in all that hydration.

This acid also plays well with most other skin actives, making it easy to pair with peels, retinols, vitamins, and other acids.

Benefits

When used in skincare products, including creams and serums, hyaluronic acid gives your complexion a boost by quickly increasing the skin's moisture level. It’s especially useful for reducing the appearance of wrinkles and age lines.

Glycerin
What It Is

Glycerin works as a humectant, it attracts moisture from the air into the stratum corneum (top layer of skin), and due to its low molecular weight, will continue to draw moisture to the deeper layers of the dermis.

Glycerin also treats several skin disorders, ranging from dry skin to wound healing. The ingredient has the potential of improving your overall internal health as well.

Due to its versatility and ability to moisturise, it’s used in everything from lotions to soaps to toners.

What It Does

How to use in your skincare routine?

Products with glycerin can be used topically multiple times a day. You can safely and effectively use this ingredient in nearly every single step of your skin care routine. Several skin care brands use glycerin when formulating everything from cleansers and toners, to serums and moisturisers.

Benefits
  • Glycerin tightens and firms - Use this ingredient for a few weeks or even a few days and we think you'll find that it plumps and softens your look significantly, especially if you have more mature skin.
  • It improves your complexion - Glycerin is non-comedogenic, meaning it won’t clog pores.
  • It brightens - Between glycerin’s rejuvenating properties and its ability to moisturise, glycerin plays a key role in keeping skin looking bright and luminous.
  • The ingredient is also a good choice for sensitive skin. Because it’s a natural component of skin, it calms redness and inflammation. It’s one of the gentler ingredients you can find in skin care products and can even help alleviate sensitivity over time.
