Why I stopped using retinol in summer and what I use instead

Living in Sydney means my skin cops serious UV exposure from November through February. The UV index regularly pushes past eleven, which is about as extreme as it gets anywhere on the planet. My morning walks along the Bondi to Bronte coastal track have always been non-negotiable, but last January I noticed something alarming. My usually reliable retinol routine was making my skin angry, raw, and photosensitive in a way it never had before, and no amount of sunscreen seemed to be enough.

For years, retinol was my ride-or-die active. I started using it in my late twenties to tackle some early sun damage and uneven texture from years of forgetting sunscreen on weekends. It worked beautifully on pigmentation and gave me that lit-from-within glow that makes foundation optional. I worked my way up to a 0.5 percent formula, then a stronger one, and genuinely believed I would never quit.

Then last summer, things shifted in a major way. A forty-degree scorcher in Adelaide over the Christmas break, a holiday in Byron Bay with too much salt water and not enough shade, and suddenly my skin was peeling around my nose, stinging when I applied serum, and looking worse than before I started any actives. Even with a hat and 50+ SPF, the combination of retinoids and brutal Australian sun was a disaster waiting to happen.

I made the call to put all retinoids in a drawer until March. Rather than just stopping and waiting, I needed a replacement strategy. I wanted something that would keep my skin smooth, address the texture issues retinol had been handling, and play nicely with the realities of an Australian summer. After months of testing, I landed on a routine that genuinely works better for the hotter months, and I have not looked back since.

The Australian sun is no joke

Australia has some of the highest UV radiation levels on the planet. The Cancer Council regularly reminds us that even on overcast days in Melbourne or Brisbane, UV can reach extreme levels. Unlike places with milder summers, our UV intensity in December and January is comparable to equatorial regions. This means any photosensitising ingredient gets a workout whether we like it or not, and that is not a gamble worth taking.

Walking through my local Priceline in Parramatta, I noticed the shelves are stocked with ingredients specifically marketed for our climate. Lighter textures, more antioxidants, and far less of the heavy-duty retinols that dominate American and European skincare marketing. Australian formulators understand that what works in a New York winter will fry your face during a Perth heatwave. The shelves are filled with niacinamide serums, azelaic acid treatments, and bakuchiol oils for good reason.

Even our leisure activities shift indoors once the UV peaks. Whether that means catching a film at Westfield, meeting mates for brekkie in a sun-dappled cafe, or playing some sic bo at Crown Melbourne with a prepaid card during a long arvo, summer downtime in this country looks completely different to anywhere else. It makes sense that our skincare should shift too.

Why retinol and summer do not mix for me

Retinol accelerates cell turnover, which sounds great until you realise it also thins the stratum corneum slightly and makes skin more vulnerable to UV-induced damage. Every dermatologist I have spoken to at clinics in Double Bay and the Sydney CBD has said the same thing. If you are using retinoids in summer, you need to be applying SPF fifty every two hours without fail, and even then, you are taking a calculated risk.

My skin is naturally on the drier side, and the combination of air-conditioning at the office in Chatswood, daily train commutes with sun streaming through the windows, and outdoor lunches in Kings Cross was creating a perfect storm. The retinol that felt nourishing in May felt stripping by November. My moisture barrier was compromised, and no amount of layering hydration on top could fix it. I was essentially applying an ingredient that was undoing all the barrier support I was trying to build.

There is a misconception that retinol toughens up skin over time. In reality, it keeps skin in a slightly sensitised state. When you add Australian summer intensity on top of that, you are asking for trouble. I learned this the hard way with three rounds of peeling that lasted weeks and made me look ten years older than I actually am. The lesson was painful but necessary.

The signs my skin was screaming for a break

The first warning was tightness after cleansing. That feeling where your face feels pulled tight like cling wrap, even when you have used a creamy cleanser. I dismissed it as dehydration and added more hyaluronic acid, but the tightness turned into flaking around my chin and forehead within days. It was not just uncomfortable, it was noticeable to everyone around me, including the barista at my local cafe who asked if I had been sunburnt.

Then came the burning sensation. Every serum, every moisturiser, even my beloved Alpha-H Vitamin B, started stinging on application. When your regular routine starts hurting, your barrier is compromised and your skin is essentially waving a white flag. I also noticed new hyperpigmentation appearing on my cheeks, which was completely counterintuitive, since retinol is supposed to fade those marks. The exact ingredient meant to help was actively making things worse.

The final straw was a weekend at a friend's place in Noosa. After a morning swim and an afternoon applying sunscreen religiously, I still ended up with a strange patchy redness across my nose bridge. It was not a classic sunburn. It was something closer to a photosensitivity reaction, the kind that happens when retinoids and UV collide. I knew right then that my summer retinol experiment was officially over and it was time for a complete routine overhaul.

My summer swap: gentler actives

Stepping away from retinol did not mean stepping away from effective skincare. I started researching alternatives that could deliver similar results without the photosensitivity. The first ingredient I reached for was bakuchiol, a plant-based retinol alternative that has been studied for its collagen-boosting properties without the UV sensitivity. Brands like Australian company Aesop and Jurlique have been quick to incorporate bakuchiol into their summer ranges, and the formulas feel like a dream on sensitive skin.

Another hero ingredient has been azelaic acid. Available over the counter at Chemist Warehouse in concentrations up to ten percent, it tackles texture, redness, and pigmentation all at once. It is also anti-inflammatory, which means it soothes rather than stresses. I have been using a fifteen percent formula from a Melbourne-based brand every second night, and the difference in my cheek texture is remarkable, particularly around the jawline where I usually see the most congestion.

For exfoliation, I ditched my old physical scrub habits entirely. Instead, I rely on a gentle PHA-based toner that smooths without abrasion. Ditching harsh scrubs for this approach was a complete game-changer for sensitive summer skin. I no longer have to choose between smooth skin and an intact barrier, which used to feel like an impossible trade-off during the warmer months.

The ingredients that saved my routine

Niacinamide has become my absolute summer MVP. It regulates oil production without drying, strengthens the moisture barrier, and fades pigmentation gradually. I am using a ten percent serum morning and night, and it pairs beautifully with everything else in my routine. It also reduces transepidermal water loss, which is essential when you are moving between air-conditioned offices and humid outdoor air multiple times a day.

Vitamin C has always been in my routine, but I have switched from L-ascorbic acid to a more stable THD ascorbate formula. The older formulation oxidised quickly in the summer heat and could sting on sensitised skin. The new version sits comfortably under sunscreen and gives me that brightening effect without any irritation. I keep it in the fridge to extend its shelf life, which is a very Australian thing to do given our energy costs and the way heat creeps into everything.

Centella Asiatica has also earned a permanent spot. Often called cica, this extract calms inflammation and supports barrier repair. I have found a gorgeous Korean-inspired formula stocked at Mecca in Sydney that I layer over my hydrating serum. It is the kind of product that makes you wonder how you ever got by without it, particularly after a long day in the sun or a flight that leaves your skin feeling parched and reactive.

How I rebuilt my routine from scratch

My morning routine now looks very different to what it did twelve months ago. I cleanse with a gentle milk cleanser, spritz with a thermal water mist, apply my THD ascorbate serum, layer a niacinamide booster, and seal it with a ceramide-rich moisturiser containing SPF. The texture is lighter, which suits the humidity, and every single product has been chosen for compatibility with Australian summer conditions rather than global trends or Instagram hype.

Evenings are where the real work happens. After cleansing, I alternate between bakuchiol and azelaic acid on different nights, always followed by a rich moisturiser containing squalane and cholesterol. Twice a week, I use a gentle PHA exfoliant and leave the rest of my actives to do their job. The whole routine takes about five minutes, which is important because if it is complicated, I will not stick with it when life gets busy between work, social plans, and weekend trips.

The biggest change has been removing all fragrances and essential oils from my routine. These seemed harmless but were quietly contributing to my sensitivity issues. Now my skin products are functional, boring, and effective, which is exactly what I want when the UV index is high and my skin is already working hard to protect itself. Simplicity has genuinely been the secret to my summer skin success.

What my skin looks like now

The results have honestly surprised me. My texture is smoother than when I was using retinol, and my pigmentation has continued to fade gradually. I have had compliments from friends at brunch in Surry Hills who noticed my skin looked fresh without being able to pinpoint why. The chronic tightness I used to feel after cleansing is completely gone, and my moisture barrier feels stronger than it has in years. My skin also tolerates the harsh Australian sun better than it ever did on retinoids.

I still use retinol, just not in summer. From March through September, it is my go-to active and I look forward to reintroducing it every year. But those four months of intense Australian sun are now reserved for gentler, smarter ingredients that work with my skin rather than against it. It is a rhythm that makes sense for where I live and how I live, rather than following a routine designed for a Northern Hemisphere climate that simply does not apply here.

If you are dealing with acne scars or stubborn pigmentation and want to see the full journey, I documented the exact routine that faded my acne scars in three months over on the blog. The summer version is just one chapter in a much longer story about listening to your skin, respecting the climate you are in, and being willing to pivot when something stops working. Your face will thank you for paying attention.
