Skincare comes in all forms to best suit various skin types and needs.

Powerhouse ingredients You Can’t Miss

“With an overwhelming number of skincare ingredients flooding social media, beauty counters and department store shelves, it can be difficult to determine which ones truly make a difference in skin health. While trends come and go, some ingredients have stood the test of time for their scientifically proven ability to transform skin at a cellular level.”

Vitamin A, often found in skincare as retinol or retinoids, promotes cell turnover, reduces fine lines, and improves skin texture and tone, making it ideal for oily, acne-prone, and aging skin types.

Vitamin A — The Queen of Skin Renewal

“Vitamin A often referred to as retinol, retinal, retinaldehyde, retinoic acid or tretinoin is one of the most potent ingredients in skincare. It works as a cell-communicating ingredient, binding to skin cell receptors and regulating cellular turnover (Cellular turnover: the natural process where old, dead skin cells on the surface are shed and replaced by new, healthy cells from deeper layers of the skin.). Retinol, for instance, boosts collagen production, reduces pigmentation and improves the appearance of fine lines. To avoid irritation, introduce it gradually to help skin build tolerance over time.”

Vitamin C is a powerful antioxidant that brightens the skin, reduces hyperpigmentation and boosts collagen production, making it ideal for all skin types, especially dull or uneven-toned skin.

Vitamin C — The Brightening Powerhouse

“Vitamin C, or ascorbic acid, is a multitasking antioxidant known for stimulating collagen production, reducing pigmentation and brightening the skin. To maximise its benefits, start with a lower concentration and gradually increase usage, just as you would with vitamin A. Look for stabilised formulations or anhydrous versions (water-free formulas) for longer-lasting potency.”

AHAs (Alpha Hydroxy Acids) exfoliate the skin's surface to improve texture, reduce fine lines and brighten, making them ideal for dry or sun-damaged skin, while BHAs (Beta Hydroxy Acids) penetrate pores to reduce acne and control oil, making them perfect for oily and acne-prone skin types.

AHAs vs. BHAs — The Exfoliation Experts

“Exfoliation is key to maintaining clear and healthy skin. It comes in two main categories:

  • Alpha Hydroxy Acids (AHAs):  AHAs are excellent for improving texture, boosting hydration and enhancing the absorption of other skincare products. Also known as glycolic and lactic acid, AHAs work on the skin’s surface by dissolving the bonds between dead cells, allowing fresh, radiant skin to emerge.
  • Beta Hydroxy Acids (BHAs): Also known as salicylic acid, BHAs are oil-soluble, making them particularly effective for acne-prone and oily skin. BHAs penetrate deep into the pores to dissolve excess oil and prevent congestion while offering anti-inflammatory benefits.

Both should be introduced gradually, especially if using other active ingredients like vitamin A or C.”

Hyaluronic acid deeply hydrates the skin by retaining moisture, plumping fine lines, and enhancing elasticity, making it ideal for all skin types, especially dry or dehydrated skin.

Hyaluronic Acid — The Ultimate Hydrator

“Despite its name, hyaluronic acid isn’t an exfoliating acid, It’s a water-binding molecule that can hold up to 1,000 times its weight in water, making it a hero ingredient for all skin types. Found naturally in the skin, HA helps maintain moisture levels to achieve a plump and dewy complexion. For best results, look for cross-linked HA with multiple molecular weights, as this ensures hydration at different layers of the skin. Unlike other active ingredients, HA can be used morning and night without risk of irritation or congestion.”

Peptides stimulate collagen production, improve skin elasticity and reduce the appearance of fine lines, making them ideal for all skin types, particularly mature or aging skin.

Peptides — The Skin’s Building Blocks

“Peptides are short chains of amino acids that act as messengers, telling the skin to produce more collagen and elastin. These ingredients help reduce fine lines, strengthen the skin barrier and improve overall firmness. Incorporating peptides to your skincare help soften expression lines and enhance skin resilience. Peptides are gentle and can be layered with other active ingredients, making them a great addition to any anti-aging regimen.”

Exosomes promote skin regeneration, boost collagen production and reduce inflammation, making them ideal for all skin types, especially aging or damaged skin in need of repair and rejuvenation.

Exosomes — The Future of Skin Regeneration

“One of the most exciting advancements in skincare, exosomes are derived from Wharton’s Jelly and function as cellular messengers. They play a crucial role in cell-to-cell communication, stimulating skin regeneration at a deep level. As a hot contender with regards to medical treatments like PRP (platelet-rich plasma), exosomes have now made their way into high-end skincare serums and ampoules, delivering unparalleled anti-aging, rejuvenation and healing benefits to skin.”

And of course, consulting a professional experienced aesthetician. By incorporating these scientifically backed ingredients into your skincare routine, you can achieve healthier, stronger and more radiant skin for the long term!”
