If you're navigating the unique challenges and concerns of changing midlife, peri and menopausal skin, you may be interested in the power of antioxidants in your skincare routine.
At the time of publishing this blog, the global cosmetic antioxidants market is valued at £115 million in 2025 and projected to reach £155 million by 2030. This rapid growth is a clear signal from manufacturers that antioxidants are crucial for developing high-performance products that address the very signs of ageing and skin concerns we've been talking about throughout several blogs, from losing our precious collagen, increasingly dryer and more dehydrated skin, discolouration, fine lines to dullness and everything in-between.
Antioxidants and their many skin benefits are big topics and only part of the overall picture of key skincare ingredients, but over recent years it has become non-negotiable for me to have a dedicated, well-formulated (multi) antioxidant product in my routine.
My only regret is that I didn't start incorporating a good antioxidant product diligently and consistently in my twenties.
That would've given me roughly another two decades of additional skin protection in small doses - but I also didn't wear sunscreen as I should've, so we are where we are :) Now that I understand the importance of antioxidants in my routine, I don't skip it any longer.
Thankfully it's relatively simple to do, but as with so much in skincare it can seem somewhat confusing and even a bit overwhelming to choose the right option for you. I completely understand that.
For midlife skin, peri- and menopause skin, which naturally produces fewer antioxidants as we age, topical application replenishes our skin's natural defence system.
Antioxidants aren’t just buzzwords; they’re backed by dermatological research showing real benefits, especially for mature skin.
Here's the science in action:
Protect Against Environmental Assaults: UV light and pollution are estimated to generate up to 80% of visible ageing signs. Antioxidants intercept free radicals, preventing DNA damage in skin cells and reducing inflammation that leads to redness or breakouts.
Boost Collagen and Firmness: As we hit midlife, collagen production drops by about 1% per year after 30. Free radicals degrade existing collagen via enzymes called matrix metalloproteinases (MMPs). Antioxidants inhibit this breakdown, preserving your skin’s scaffold for a smoother, more resilient complexion.
Brighten and Even Tone: By calming oxidative stress, they help fade dark spots and hyperpigmentation—common in midlife due to sun exposure and hormonal changes—revealing a more luminous glow.
Enhance Barrier Function: They support the skin’s lipid barrier, locking in moisture and reducing sensitivity, which is a game-changer for drier, mature skin.
As we are going through the years and our skins are changing these skin benefits can help translate to visible outcomes: fewer fine lines, better hydration, less discolouration and overall a more even and more radiant complexion.
Again this isn't the full skincare story - of course we also need barrier care through hydration and moisture support, gentle exfoliation, a solid cleansing routine, sun protection and a good Retinoid, but antioxidants are a key part of this overall picture.
Before we dive in, just a reminder about the previous blog: Collagen Banking for Midlife Skin, where I talked about how investing in collagen preservation (banking) is like saving for your skin’s future.
One crucial step / component of Collagen Banking that I highlighted?
Incorporating antioxidants (AOX) into your routine.
In today's blog, I hope to break antioxidants as an ingredient category down for you so that you have more clarity about what they are, why we use them, how they relate to midlife skin in particular and some of the key options on the market.
We'll look at why antioxidants deserve a starring role specifically in your morning skincare routine and the science that speaks directly to their defence against the many oxidative and other stresses we face as we age.
Key Takeaway: Antioxidants neutralise free radicals from UV, pollution, and hormonal changes, preserving collagen and brightness in midlife skin – a must for anti-ageing routines.
At their core, antioxidants are molecules that act as your skin’s bodyguards against free radicals. In skincare, antioxidants are derived from natural sources (like plants and vitamins) and formulated into serums, creams, or essences.
These unstable atoms (free radicals) are produced by everyday exposures like UV rays and pollution, as well as internally through chronic inflammation, stress, and glycation.
Think of it as rust forming on metal; without protection, your skin’s structure weakens over time.
Free radicals trigger a process called oxidative stress, which damages skin cells, breaks down collagen and elastin (the proteins that keep your skin firm and plump), and accelerates visible ageing like wrinkles, sagging, and hyperpigmentation to name a few.
Alongside this, we know that hormonal changes (i.e., oestrogen loss) during peri and menopause can exacerbate these processes and accelerate the rate of stress and inflammation in the body.
They’re not magic, but science shows they’re mighty: they neutralise free radicals by donating electrons, stabilising them before they can cause havoc in our bodies through chronic inflammation (inflammaging) over time.
Free radical damage and oxidative stress are of course not limited to just our skin, it's a factor throughout our bodies and that's why we will also look into the whole area of nutrition / ingesting our antioxidants - not just applying them topically through our skincare.
Consistently supporting our bodies and skins with antioxidants can provide a significant protective factor for skin and help slow down signs of ageing, even though it won't eliminate it.
Key Takeaway: Recent studies show antioxidants mimic oestrogen’s protective effects in menopausal skin, reducing inflammaging by up to 40% with daily use.
UV Protection Boost: Enhance sunscreen by neutralising 80% of free radical damage.
Collagen Preservation: Inhibit MMPs, maintaining firmness amid oestrogen decline.
Hyperpigmentation Reduction: Plant-based options like Resveratrol fade spots by 25-30% in trials.
Barrier Support: Improve hydration in dry, sensitive menopausal skin.
Timing matters in skincare, and mornings are prime time for antioxidants.
During the day, your skin faces peak exposure to UV (even on cloudy days), urban and other types of environmental pollutants, which ramp up free radical production.
Applying AOX first thing helps to create a protective shield, neutralising threats before they penetrate.
Research supports this: topical antioxidants enhance sunscreen’s efficacy, reducing UV-induced damage without interfering with your SPF.
In your routine, use them after cleansing and toning, before moisturiser and sunscreen. A lightweight serum absorbs quickly, layering seamlessly under make-up.
Caveat: Night-time application has its place (for repair), but mornings are about prevention, vital as our skin’s repair mechanisms slow with age.
Key Takeaway: Pair morning AOX with SPF for up to 50% better protection against environmental ageing in midlife skin.
Not all antioxidants are created equal, but these evidence-based heroes are powerhouse options and often more recognisable on ingredient lists.
Vitamin C (L-Ascorbic Acid) (Derivatives: Sodium Ascorbyl Phosphate, Magnesium Ascorbyl Phosphate, Ascorbyl Glucoside, Tetrahexyldecyl ascorbate / Ascorbyl Tetraisopalmitate): The gold standard, this water- or oil-soluble vitamin brightens by inhibiting melanin production, supports collagen synthesis, and fights free radicals. It’s especially potent to help address photo-ageing, reducing wrinkles with consistent use.
Vitamin E (Tocopherol): A fat-soluble antioxidant that pairs beautifully with Vitamin C, it stabilises cell membranes and locks in moisture. It can help to reduce inflammation and UV damage, improving hydration in dry, ageing complexions.
Ferulic Acid: Derived from plants like rice bran, this boosts other antioxidants’ stability (e.g., extending Vitamin C’s shelf life). It neutralises free radicals across UV and visible light spectra, protecting against pigmentation and collagen loss.
Resveratrol: Sourced from grapes and berries - it can activate sirtuins (proteins linked to longevity), reduces inflammation, and preserves collagen.
Bonus Antioxidant Powerhouse Ingredients:
Other notable mentions include:
Coenzyme Q10 (energises cells, with levels dropping by 30% by midlife),
Astaxanthin (a carotenoid that is a staggering 6,000 times stronger than Vitamin C at quenching free radicals)
Pycnogenol (from pine bark, known for its anti-inflammatory properties)
Ergothioneine and Superoxide Dismutase (powerful enzymes that help protect against oxidative stress).
Yes, Vitamin A (specifically retinol and its derivatives) has antioxidant properties.
While it does help to neutralise free radicals, its primary and most celebrated role in skincare is its ability to communicate with skin cells, encouraging faster turnover and boosting the production of new collagen.
This makes it a crucial part of a slowing-down-signs-of-ageing routine, but its mechanism of action is distinct from a pure antioxidant like Vitamin C. It’s a powerful two-in-one ingredient that is often best used at night for repair and renewal.
Vitamin C is is a superstar ingredient, but its acidity can sting sensitive or rosacea-prone skin.
If any form of Vitamin C causes redness or prolonged tingling and/or itching, swap it out, these science-supported alternatives can also help deliver antioxidant protective properties:
Niacinamide (Vitamin B3): A multitasking gem, it strengthens the barrier, evens tone, and reduces inflammation while providing mild antioxidant protection. Studies show it minimises pores and fine lines.
Green Tea Extract (EGCG): Rich in polyphenols, it soothes oxidative stress and protects collagen like Vitamin C, but is gentler.
Resveratrol or Grape Seed Extract: These plant polyphenols offer broad-spectrum defence without irritation.
Astaxanthin or Carotenoids: These carotenoids outperform Vitamin C in some free radical scavenging tests. They’re non-irritating, hydrate deeply, and improve elasticity.
Licorice Root or Centella Asiatica: These botanicals brighten and heal while neutralising radicals.
Remember our Collagen Banking blog?
Antioxidants are the vault’s lock - they shield your precious collagen from free radical damage. By inhibiting MMP enzymes and supporting collagen synthesis, they ensure your “bank” stays full, delaying sagging, fine lines and wrinkles.
Pairing AOX with collagen-boosters like collagen peptides and retinoids as part of your overall routine can amplify results, as seen in studies where combos reduced MMP activity by 50%. And with a holistic twist, your diet becomes the interest-earning account, compounding those gains.
Your Next Step:
Incorporating antioxidants into your morning routine, and your plate, is a simple, science-smart way to support your skin’s midlife journey.
Start small: cleanse, apply your AOX serum, hydrate, and shield with SPF.
Want to learn more? In our next blog, we will do a deep dive into Vitamin C - its different forms, efficacy, and how to make it work for you.
Q1: Can antioxidants completely prevent signs of ageing in menopausal skin?
A: No, but they significantly slow it. Recent research shows topical and dietary antioxidants reduce wrinkles and discolouration by 25-40% by neutralising free radicals and supporting collagen, though genetics and lifestyle also play roles.
Q2: How do antioxidants interact with hormonal changes during peri-menopause?
A: Oestrogen decline reduces natural antioxidants, accelerating oxidative stress. Antioxidants like Resveratrol (a phytooestrogen) mimic this protection, calming inflammation and preserving barrier function for drier, more sensitive skin.
Q3: What are the best emerging antioxidants to try for midlife skin?
A: Beyond classics, try Bakuchiol for gentle renewal and Glutathione for detox brightening. Dietary standouts include Moringa and Spirulina for elasticity and reduced hyperpigmentation.
Q4: Can I combine antioxidants with retinol or other actives?
A: Yes – use antioxidants in the morning and retinol at night to avoid irritation. Studies confirm this duo boosts collagen by 50% without compromising stability.
Q5: Do oral antioxidant supplements work as well as topicals for skincare?
A: They complement each other; orals like CoQ10 provide systemic support, improving firmness by 30%, while topicals target surface damage. Consult a doctor for personalised dosing.
Now that you're armed with all the information, here’s a simple checklist to help you choose your next antioxidant serum with confidence when you're out shopping:
Look for a lightweight formula: Gels, serums, or light lotions are usually best for quick absorption - and also helpful in using underneath sunscreen and/or makeup.
Check the Ingredient List: Look for a potent mix of key antioxidants like Vitamin C, Vitamin E, and Ferulic Acid. A multi-antioxidant product can often more effective than one with a single ingredient - it all depends on what your skin tolerates best.
Note the Packaging: Is the product in an opaque bottle or pump dispenser? This is crucial for protecting ingredients like Vitamin C from light and air, which can cause them to become unstable and less effective.
Consider your Skin's Sensitivity: If you have sensitive skin, opt for gentle alternatives like Niacinamide, Green Tea Extract, or Astaxanthin.
Look for Key Claims: Check the product description for claims like 'protects against environmental damage,' 'brightens skin tone,' and 'protects/supports collagen synthesis'.
Remember, the best product is one that works for your unique skin.
Many brands advertise their inclusion rates for Vitamin C on their products - often implying that the higher the percentage of Vitamin included, the better and more effective the product would be.
Higher percentages don’t always mean better results, especially for midlife skin that may be more reactive.
Ascorbic Acid (L-Ascorbic Acid) is often found at 5-20%, but high concentrations (above 10%) can irritate sensitive or menopausal skin without added benefits, as stability and penetration matter more.
Ascorbyl Glucoside(2-10%) is gentler but less potent, ideal for more gradual brightening.
Ascorbyl Tetraisopalmitate (ATIP), my personal choice, is effective at just 1-3% due to its oil-soluble nature, offering deep penetration and minimal irritation for mature skin. Studies show 3% ATIP matches 10% Ascorbic Acid for collagen support and hyperpigmentation reduction with better tolerance.
* It’s not always possible to know the inclusion levels of all active ingredients as that’s not something brands readily share - but when it comes to Vitamin C’s and Retinoids you may see more brands sharing the percentages included as part of their marketing strategy, and also for more clear customer information for the purpose of gauging tolerance to the particular Vitamin C / Retinoid in the formulation.
** You may also find that a Vitamin C product that has worked for you previously now cause some reactiveness in your skin.
It just means that while the product hasn't changed your skin may be undergoing some changes, ie. as a result of losing estrogen. There is nothing wrong with your skin and it's certainly not your fault - it's just a signal that perhaps it's time to look for a different derivative of Vitamin C or consider a Vitamin C - free product to test how your skin responds.
You’ve chosen your perfect Vitamin C - now, how do you use it effectively?
In Part 3 of our 'Vitamin C For Midlife Skin Decoded' guide I’ve compiled the 16 most common questions about Vitamin C in skincare, from layering with Retinol and Niacinamide and how long it can take to see results, to when is best to use it in your routine - and much more.
This Q&A is your cheat sheet for making Vitamin C work hardest for your midlife skin.
You know Vitamin C is crucial for your 'collagen banking', but which product should you buy?
The difference between the five types—L-Ascorbic Acid, Ascorbyl Tetraisopalmitate, Sodium Ascorbyl Phosphate, Magnesium Ascorbyl Phosphate, and Ascorbyl Glucoside -can make or break your routine.
In Part 2 of our 'Vitamin C For Midlife Skin Decoded' guide, I break down the science of oil-soluble vs. water-soluble forms so you can shop smarter, avoid irritation, and invest in a stable serum that actually works for your sensitive, midlife skin.
Plus, a complete list of alternative ingredients if Vitamin C just isn't for you.
If you’re 35+ and noticing changes in firmness, brightness and resilience, this Part 1 guide explains why Vitamin C belongs in your morning routine with SPF.
Vitamin C is biologically indispensable: it is an essential co-factor for collagen synthesis and a master water-soluble antioxidant that neutralises free radicals from UV and pollution while regenerating Vitamin E (Tocopherol).
You’ll find a clear overview of the main forms used in skincare and who they suit: L-Ascorbic Acid, Ascorbyl Tetraisopalmitate or Tetrahexyldecyl Ascorbate, Sodium Ascorbyl Phosphate, Magnesium Ascorbyl Phosphate, and Ascorbyl Glucoside.
If your skin is sensitive or you prefer a different route, I share effective alternatives that support antioxidant defence and even tone without the sting.
