The sun is actually here. My skin needs a completely different game plan.

Six months in. We started this series in January when my skin was dry, tight, and miserable. And now here we are in June, and the problem is sort of the opposite. It’s warm. It’s bright. There’s actual sunshine. And my skin is oily in the afternoon, flushed after being outside, and occasionally doing things I wasn’t expecting.

Summer skincare is a whole different conversation from winter skincare. The threats are different, the priorities are different, and the products that served you brilliantly in January are probably working against you right now. So let’s talk about what June actually needs. In my experience, most skincare content either focuses on winter dryness or offers general tips that apply to any season. June is specific. Let’s get specific.

Heat and Humidity Are Changing Your Skin’s Behaviour

This is the big one, and it underpins everything else in this post. In winter, the problem was a lack of moisture everywhere. Now the problem is almost the opposite. Warmer temperatures increase your sebaceous gland activity. Higher humidity means your skin retains more of its natural moisture. On paper, that sounds like a win. In practice, it means more oil, more shine by midday, and more potential for pores to get clogged.

The products you need in June are genuinely lighter than what you needed in January. Not just marginally lighter. If you’re still using a cream-based moisturiser from a tub, this is the moment to swap it for a gel or water-based formula. Your skin is retaining moisture more easily now. A heavy cream on top of a more humid environment often just adds to congestion rather than solving a problem.

Your cleanser matters more in summer, too. A gentle foaming or gel cleanser in the morning removes overnight oil and sweat without stripping your barrier. In the evening, especially after being outside and reapplying SPF, a proper double cleanse helps ensure all that residue is truly gone.

The Johnson & Johnson expert summer skincare guide from dermatologist Dr Joshua Zeichner at Mount Sinai clearly covers the effects of oil and humidity and is a useful read.

After-Sun Care: The Evening Routine That Actually Matters

This one doesn’t get talked about nearly enough. Most skincare content focuses on what you do in the morning to protect your skin. But what you do in the evening after a day in the sun is equally important. Possibly more important on the days you’ve been outside for a long time.

After the sun, your skin needs cooling and soothing before anything else. A lukewarm or cool shower rather than a hot one. Hot water after sun exposure can worsen inflammation and redness. After your shower, pat your skin gently dry rather than rubbing.

Aloe vera gel is the classic after-sun ingredient, and it earns its reputation. It’s genuinely anti-inflammatory, cooling, and hydrating. Keeping a bottle in the fridge makes it even more effective. Apply it liberally to anywhere that’s been in the sun. On your face, neck, arms, wherever.

After aloe, a lightweight hydrating serum or moisturiser helps replenish what the day has taken. Look for hyaluronic acid or centella asiatica, which is soothing and great for heat-stressed skin. Skip the activities in your evening routine on nights after significant sun exposure. Give your skin a break. Save the retinol and exfoliants for evenings when you haven’t been roasting in the garden.

URMC’s summer skin tips from Dr Mara Weinstein Velez has a good section on post-sun care that covers the cool shower and aloe approach in a clinically grounded way.

Pool Water, Sea Water, and What They Do to Your Skin

This is something I genuinely hadn’t thought much about before looking into it. Both chlorinated pool water and salt water affect your skin, and in different ways. Understanding what they do helps you look after your skin better around them.

Chlorine is a disinfectant. It does its job brilliantly in keeping swimming pools clean. But it can also strip your skin’s natural oils and disrupt the outer layer of your skin barrier, leaving it feeling dry, tight, and sometimes itchy, even in the heat of summer. If you swim regularly, rinsing off immediately afterwards with fresh water is important. Then moisturiser while your skin is still slightly damp. It makes a real difference.

Salt water is generally gentler on the skin than chlorine and has some anti-inflammatory properties. But prolonged exposure is still drying. The combination of salt, sun, and wind at the beach is genuinely dehydrating for your skin. So after a beach day, a proper rinse and a good moisturiser is the priority before anything else.

One thing worth knowing for both: apply your SPF before getting in the water, let it absorb properly first, and reapply immediately after coming out. Water resistance in sunscreen is not the same as waterproof. No sunscreen is truly waterproof. Reapplication after swimming is non-negotiable if you’re going back into the sun.

Sweat, Prickly Heat, and Managing Summer Skin Issues

Sweat is your body’s cooling system, and it’s working hard in June. But when sweat mixes with bacteria, oil, and sunscreen residue on your skin, it can cause problems. Clogged pores, breakouts on the face and body, and, for some people, something called prickly heat, which is a rash caused by blocked sweat glands.

The AAD advises blotting sweat rather than wiping it away. Wiping can drag bacteria across the skin and irritate it. A gentle blot with a clean cloth is kinder. Keeping your workout clothes, towels, and anything that sits against your skin clean matters more in summer than in winter because bacteria thrive in warmth and moisture.

If you’re prone to body breakouts in summer, which are really common, look for non-comedogenic body products. Your body lotion, body SPF, and even shower gel all come into contact with your skin. Fragrance-free and oil-free formulas are generally safer for breakout-prone skin. A salicylic acid body wash, used a few times a week, can help keep body acne under control.

For prickly heat, the key is staying cool, wearing loose, natural fabrics like cotton, and avoiding heavy products that can smother your skin. A light calamine lotion or a product with colloidal oatmeal can help soothe the rash if it appears.

The American Academy of Dermatology’s guide to summer skin problems covers all of this in practical detail and is worth bookmarking for the season.

Retinol in Summer: Do You Keep Going or Dial Back?

This is a question I had to look into properly because I got conflicting information from different sources. The short answer is: you don’t have to stop using retinol in summer, but you need to be smarter about how you use it.

Retinol increases your skin’s sensitivity to UV light. That’s not a reason to abandon it, but it’s a reason to be extra rigorous about your morning SPF. Always use retinol at night, and always follow with broad-spectrum SPF the next morning. That combination is safe and effective.

The thing to watch is whether you’ll have days of prolonged sun exposure. A day at the beach or a festival weekend where you’re in direct sun for extended periods is a moment to skip your retinol the night before. Give your skin a couple of days’ rest before heavy sun exposure, and let it rebuild a bit of natural protection.

If you’ve been building up to a higher concentration of retinol over the winter and spring months, you might also find that summer is a natural moment to step back down to a slightly lower strength. Your skin is working harder to manage UV exposure. Keeping your activities slightly gentler during peak summer gives them more capacity to cope.

Schweiger Dermatology’s pre-summer checklist addresses this timing question around actives really well from a clinical perspective.

Hydration From the Inside Out (Again, Yes, Still)

I know. I’ve mentioned this in almost every post. But summer is when it becomes genuinely urgent, not just sensible advice. You lose significantly more water through sweat in warm weather. Your body and your skin are working harder to regulate temperature. Dehydration shows up on your face faster in summer than at any other time of year.

The visible signs of skin dehydration in summer look different from those in winter. In winter, it was dryness and flakiness. In summer, it tends to be dullness, a slight sallowness, fine lines looking more pronounced, and skin that’s oilier on the surface but feels tight underneath. The skin produces more oil to compensate for the fact that it’s losing water quickly. More oil doesn’t mean more hydration.

Drinking more water is genuinely the most effective thing you can do. Aim for more than you think you need, especially on hot days or after exercise. Foods with high water content help too. Cucumbers, watermelon, strawberries, and leafy greens are all hydrating from the inside in a way that your hyaluronic acid serum simply cannot replicate on its own.

A facial mist is a lovely summer addition, too. Not as a replacement for moisturiser, but as a midday refresh. Keep one in the fridge or your bag. A quick spritz of aloe or hyaluronic acid mid-afternoon, when you’re feeling flushed and dry, is a small pleasure that genuinely helps.

Sun-Induced Pigmentation Is Happening Right Now

One thing June often brings on, particularly for people prone to it, is increased pigmentation. Those freckles you didn’t notice before suddenly look darker. Old acne scars or dark spots that were fading through winter and spring suddenly look more visible again. For people with melasma, the condition can worsen significantly with sun exposure.

This is another reason why consistent SPF is so important in June. Every day of unprotected sun exposure deepens existing pigmentation. It’s not a cosmetic vanity issue. It’s about stopping damage from accumulating.

If you’re dealing with noticeable hyperpigmentation, June is not the time for aggressive treatments. Procedures like chemical peels and lasers are generally avoided in summer because freshly treated skin is highly vulnerable to sun damage. Think of summer as the time to protect and maintain, not to treat. The treatment occurs in autumn and winter, when UV exposure is low.

In the meantime, niacinamide and Vitamin C in your daily routine continue to quietly, consistently work on existing dark spots. They’re not dramatic overnight fixes. But used consistently alongside SPF, they genuinely help.

The June Mindset: Protection Is the Priority

Looking back across all six months, the journey has been a real education. January was about rescue. February was about recovery. March was about transition. April and May were about building good habits. And June is where all of that pays off, or doesn’t, depending on how consistent you’ve been.

The thing I keep coming back to is that summer skin health is built over years, not weeks. The SPF you put on today isn’t just protecting you from a sunburn tomorrow. It’s protecting your fifty-year-old self from hyperpigmentation, wrinkles, and skin cancer risk that compounds quietly over decades.

That feels weighty. But it also feels motivating, in a way. Every good habit matters. Every morning SPF counts. It all adds up in a direction you can be glad about later.

Enjoy June. Get outside. Just be sensible about it.
