The Importance of Sunscreen

f there is one piece of skincare advice that Dr Karwal gives to every single patient at Karwal Aesthetics, it's this: wear SPF every day, without exception. Not just on sunny days. Not just on holiday. Every single day of the year.

Sunscreen is the most important product in your entire skincare routine. You can invest in the best serums, the most advanced treatments, and the most meticulous daily habits, but without daily SPF, you are undoing much of that good work. UV radiation is the single biggest contributor to premature skin ageing, pigmentation, and skin cancer, and it doesn't take a cloudless sky to cause damage.

Why Sunscreen Matters More Than You Think

Many people think of sunscreen as something you apply on a beach holiday and forget about the rest of the year. In reality, your skin is exposed to UV radiation every day, regardless of the season or the weather.

UVA rays are present all year round. Unlike UVB rays, which are strongest in summer and are the primary cause of sunburn, UVA rays remain consistent throughout the year. They penetrate through clouds, through glass, and deep into the skin, where they break down collagen and elastin over time. This is the radiation responsible for the majority of premature ageing, including wrinkles, fine lines, loss of firmness, and age spots. Every day you step outside without protection, this invisible damage is accumulating.

UV exposure is the leading cause of skin cancer. Skin cancer is one of the most common cancers in the UK, and the vast majority of cases are linked to UV exposure. Repeated, unprotected sun exposure causes mutations in the DNA of your skin cells, which over time can lead to the development of cancerous growths. Wearing a broad spectrum SPF daily is one of the most effective and simple steps you can take to reduce your risk.

Sunburn is a sign of real damage. Sunburn isn't just uncomfortable. It's a visible indication that your skin's DNA has been damaged by UV radiation. Repeated sunburns significantly increase the risk of skin cancer and accelerate the ageing process. Even on overcast days, UV radiation can penetrate cloud cover and cause burns, which is why daily protection is essential regardless of the weather.

Not wearing SPF makes every skin concern worse. This is something many people don't realise. If you're dealing with hyperpigmentation, acne scarring, melasma, fine lines, or uneven skin tone, unprotected sun exposure will actively worsen all of these concerns. UV radiation stimulates excess melanin production, inflames post-acne marks, and breaks down the collagen your skin needs to stay smooth and firm. SPF is not just prevention. It is an essential part of treating and managing existing skin concerns.

What to Look for in a Sunscreen

Not all sunscreens are created equal, and choosing the right one for your skin type can make the difference between a product you love wearing daily and one that sits unused in a drawer.

When selecting a facial sunscreen, look for broad spectrum protection, which means the product shields against both UVA and UVB rays. Choose a minimum of SPF 30, though SPF 50 is preferable for daily use. Reapply every two hours if you are spending extended time outdoors, and remember that no sunscreen offers complete protection on its own. Hats, sunglasses, and seeking shade during peak hours are all important complementary measures.

Finding the right sunscreen for your face can feel overwhelming, especially if you have sensitive, oily, or breakout-prone skin. To help, here are some of the sunscreens we recommend at Karwal Aesthetics for different skin types and needs.

Our Recommended Sunscreens

Best face SPF overall: La Roche-Posay Anthelios Anti-Shine Sun Cream Gel SPF50+

This is an excellent all-rounder and a fantastic option if you suffer from acne or breakouts. Many face SPFs can feel heavy and clog pores, but this gel-cream formula from La Roche-Posay has been specifically formulated with blemish-prone skin in mind. It offers SPF50+ protection with a super lightweight feel that won't aggravate your skin. Mineral formula. From £20.00.

Best SPF for post-procedure skin: Obagi Sun Shield Mineral SPF50+

If you've recently had a cosmetic treatment, your skin needs extra care and protection. Obagi Sun Shield Mineral is a sheer, quick-absorbing formula that is ideal for sensitive, post-procedure skin. It provides comprehensive broad spectrum protection against UVA and UVB rays, as well as defence against infrared rays and high energy visible light, including blue light from screens, which can contribute to premature skin ageing. It's non-comedogenic, hypoallergenic, and dermatologist tested, making it one of the gentlest yet most effective SPFs available. From £67.00.

Best nourishing face SPF: Vichy Capital Soleil UV-Age Daily SPF50+

This sunscreen goes well beyond basic protection. Packed with Vitamin E, a peptide complex, 2% niacinamide, and Vichy's Volcanic Mineralising Water with probiotic fractions, it actively nourishes and cares for your skin while shielding it from UV damage. If you want your SPF to double as a skincare treatment, this is a brilliant choice. Chemical formula. From £16.50.

Best face SPF for normal and dry skin: Ultra Violette Queen Screen Luminising Sun Serum SPF50+

Dry skin needs an SPF that hydrates as well as protects, and this antioxidant-infused sun serum delivers on both fronts. It provides SPF50+ protection against UVA and UVB rays as well as free radicals and environmental aggressors, while intensively hydrating the skin and brightening the complexion with added Vitamin C. Its lightweight serum texture absorbs beautifully without leaving any greasy residue. Chemical formula. From £30.00.

Best face SPF for oily skin: SkinCeuticals Advanced Brightening UV Defence SPF50+

Oily and combination skin types need an SPF that protects without adding shine or congesting pores. This formula includes tranexamic acid and niacinamide, both of which help regulate oil production, prevent discolouration, and keep the complexion balanced throughout the day. It works hard to protect your skin from the sun while keeping oiliness at bay. Chemical formula. From £50.00.

Best lightweight face SPF: CeraVe AM Facial Moisturising Lotion SPF50+

If you want an affordable, accessible SPF that feels like nothing on the skin, this is it. Supercharged with three ceramides, niacinamide, and Vitamin E, it locks in moisture, balances the complexion, and creates softer, smoother looking skin. Its incredibly lightweight texture makes it easy to wear every day, and it's widely available in most pharmacies. Chemical formula. From £13.20.

Best waterproof face SPF: Shiseido Expert Sun Protector Face and Body Lotion SPF50+

For those who are active outdoors, this is the SPF to reach for. Enriched with nourishing ingredients, it moisturises while shielding the skin's surface from UV damage. Its weightless feel is comfortable for all-day wear, and thanks to Shiseido's SynchroShield technology, the formula actually becomes stronger when it meets water, sweat, or heat, keeping your skin protected in every situation. Chemical formula. From £34.00.

Best all-round daily SPF moisturiser: Medik8 Advanced Day Total Protect SPF30

This is one of our favourite products at Karwal Aesthetics and a fantastic option for anyone who wants their moisturiser and SPF combined in a single step. Advanced Day Total Protect goes far beyond basic sun protection. It delivers SPF 30 with ultra-high 5-star UVA defence alongside a comprehensive environmental shield against blue light from screens, air pollution, infrared damage, and glycation, a process where sugars damage collagen and elastin within the skin. Moringa extract forms a protective barrier on the skin's surface to neutralise pollutants, while carnosine works to protect collagen from breakdown. The formula is lightweight, non-greasy, and leaves an invisible finish that sits beautifully under makeup, making it effortless to wear every single day. If you want one product that covers hydration, sun protection, and environmental defence, this is it. Chemical formula. From £39.00.

Best high-protection SPF moisturiser: Medik8 Advanced Day Ultimate Protect SPF50+

If you want the highest level of protection Medik8 offers, Advanced Day Ultimate Protect is the one to choose. It delivers SPF 50+ with PA++++ rated UVA defence alongside the same comprehensive environmental shield as its SPF 30 counterpart, protecting against blue light, pollution, infrared, and glycation. What sets this product apart is the addition of photolyase, a next-generation DNA repair enzyme that actively supports your skin's natural repair mechanisms after UV exposure. This means it doesn't just protect your skin from damage, it helps to reverse it. The formula is infused with squalane and multi-weight hyaluronic acid for deep, lasting hydration, and it delivers a non-greasy, non-comedogenic, invisible finish on all skin tones. For patients who spend more time outdoors, who have had recent skin treatments, or who simply want the most advanced daily protection available, this is an outstanding choice. Chemical formula. From £49.00.
