Today we\u2019re exploring the roles of ascorbic acid and retinoids in treating hyperpigmentation. Do you have hyperpigmentation? Wondering how you can encourage it to fade? We\u2019re here to guide you through the science and application of these powerful ingredients, and how they can help you achieve brighter, more even-toned skin. <\/p>\n

Understanding Hyperpigmentation<\/strong><\/p>\n

Before we talk about the ingredients, we need to understand what hyperpigmentation<\/a> is. Hyperpigmentation refers to dark patches of skin, usually brown or grey in colour \u2013 or oftentimes just darker than your skin tone. It\u2019s not harmful, it\u2019s just the result of your skin producing too much melanin.(1)<\/p>\n

Common reasons why it might appear include sun damage<\/a>, hormonal changes (for example during pregnancy), medications (including HRT or oral contraceptives), or post-inflammatory scars<\/a> from acne. Uneven skin tone can sometimes dampen our confidence, but not to worry, because both ascorbic acid and retinoids can help manage signs of hyperpigmentation \u2013 the trick is knowing how to use them correctly.<\/p>\n

What Is Ascorbic Acid (Vitamin C)?<\/strong><\/p>\n

Ascorbic Acid is one of the most well researched cosmetic ingredients around, and is an antioxidant that\u2019s essential for a number of processes in the skin, like collagen synthesis.(2) And that\u2019s not all. This vitamin\u2019s biggest benefit is that it inhibits an enzyme called tyrosinase \u2013 which studies show is responsible for melanin production. By doing so, vitamin C can help fade existing hyperpigmentation and prevent new patches from forming.<\/p>\n

Ascorbic acid can help manage post-inflammatory hyperpigmentation (PIH). This is pigmentation caused by certain conditions, including acne. It\u2019s known to reduce inflammation, promote wound healing and can even help prevent PIH. (3)<\/p>\n

Choosing A Vitamin C\/Ascorbic Acid Serum<\/strong><\/p>\n

Of all the vitamin C types, ascorbic acid currently has the most research to back up its efficacy in skincare. But not every product is created equal. So when choosing yours, there are several things to consider to ensure you\u2019re making the right choice. <\/p>\n

1. The Concentration Of Ascorbic Acid<\/strong><\/p>\n

Look for ascorbic acid concentrations at around 15%. Any higher than 20%, and evidence has shown that it won\u2019t add much more benefit. It also increases the likelihood of skin irritation. This is especially true if you\u2019re sensitive, or using retinoids at the same time.(4)<\/p>\n

2. Stability And Packaging<\/strong><\/p>\n

Ascorbic acid is an unstable ingredient that\u2019s prone to oxidation when exposed to light, air and heat. Therefore, look for serums in dark or opaque bottles. The right packaging minimises the ascorbic acid\u2019s exposure to air and light. Also, buying the serum in smaller quantities can help keep the formulation fresh for longer.<\/p>\n

3. Skin Type Compatibility<\/strong><\/p>\n

Ascorbic acid can work wonders on many different skin types. However, if you have rosacea, we advise avoiding ascorbic acid to prevent more irritation. If you are using retinoids, we’d also recommend using your ascorbic acid at a different time of the day, ideally in the morning before your SPF30+ sunscreen. <\/p>\n

How Retinoids Help Fade Hyperpigmentation<\/strong><\/p>\n

Now let’s talk about retinoids, the multi-tasker of the skincare world. Retinoids are derived from vitamin A and come in various forms, from over-the-counter retinol to prescription retinoids like adapalene and tretinoin. Retinoids are renowned for their ability to encourage skin cell turnover, boost collagen production and improve the skin’s texture. This can help manage signs of hyperpigmentation. <\/p>\n

Over time, your complexion becomes smoother, more radiant, and more even-toned. They work on pigmentation and atrophic scarring<\/a> left from acne, photodamage and melasma<\/a>.(5)<\/p>\n

Can you use Ascorbic Acid and Retinoids together?<\/strong><\/p>\n

To experience the full potency of this powerful pair, you\u2019ll need to incorporate them into your skincare routine safely. Start with a gentle cleanser, followed by a vitamin C serum in the morning to provide antioxidant protection throughout the day. Be sure to follow up with an SPF30 or higher every day, like the Dermatica SPF50 Photoageing Defence Sunscreen. <\/a><\/p>\n

In the evening, after cleansing, apply your retinoid to aid in cellular turnover and fading of dark spots. Remember to finish your routine with a moisturiser<\/a>, and you can also use a serum with hyaluronic acid<\/a> if your skin needs extra moisture. <\/p>\n

Conclusion<\/strong><\/p>\n

There you have it: ascorbic acid and retinoids \u2013 the ultimate duo when it comes to addressing hyperpigmentation topically. Both have unique abilities to fade existing dark spots, prevent new ones from forming and improve overall skin quality. And when used correctly, they\u2019ll leave you with a clearer and more even complexion. <\/p>\n
