Finding a sunscreen that doesn't feel like a heavy, greasy mask in Mauritius' heat can be a challenge. The COSRX Ultra-Light Invisible Sunscreen is a fast-absorbing chemical sunscreen that provides high UV protection with a weightless, non-sticky finish, making it an ideal daily shield for our humid climate.

If you have oily or combination skin and dread applying sunscreen because it often feels heavy, causes breakouts, or leaves a white cast, this formula is designed for you. It feels more like a lightweight lotion than a traditional sunscreen, absorbing quickly to a natural finish without clogging pores or leaving your skin looking shiny.

• Texture: A very lightweight, watery gel-lotion.
• Finish: Natural, satin finish. Not overly dewy or matte.
• White Cast: None. It is completely invisible on all skin tones, including deep complexions.
• Best For: Oily, Combination, and Normal skin types.
• Key Benefit: High SPF & PA protection that feels comfortable and weightless, even in high humidity.

In the morning, a simple and effective routine is all you need for protection.

1. Cleanser: Wash your face to create a clean base.
2. THIS PRODUCT (Sunscreen): Apply a generous amount as the final step of your routine. See "How to Use" for the correct dosage.
3. (Optional) Moisturiser: If you have dry skin, you may apply a light moisturiser 5-10 minutes before the sunscreen.

Note: Already own a similar product? Finish that first to avoid waste (substitute, don’t stack).

This sunscreen should be the final step of your morning skincare routine, right before makeup.

• Minimalist (2-3 steps): 1) Cleanser → 2) (Optional) Moisturiser for drier skin types → 3) THIS PRODUCT (Sunscreen)
• Expanded (4-5 steps): 1) Cleanser → 2) Hydrating Toner/Essence → 3) Targeted Serum (e.g., Vitamin C) → 4) (Optional) Moisturiser → 5) THIS PRODUCT (Sunscreen)

Wait Times: Allow 30-60 seconds between watery layers. Wait at least 1-2 minutes after your last serum or moisturiser before applying sunscreen to prevent pilling. Wait another 1-2 minutes before applying makeup.

Sunscreen is for daytime use only. Your evening routine should focus on cleansing and repair.

• Minimalist (2-3 steps): 1) Cleanser (use an oil cleanser first to break down sunscreen, then a water-based cleanser) → 2) Targeted Serum (optional) → 3) Moisturiser

Double Cleansing is Key: To ensure all sunscreen is removed, start your PM routine with an oil-based cleanser, massage it onto dry skin, then rinse with water. Follow with your regular foam or gel cleanser.

• UV Filters: Chemical Filters (Drometrizole Trisiloxane [Mexoryl XL], Ethylhexyl Triazone [Uvinul T 150], Diethylamino Hydroxybenzoyl Hexyl Benzoate [Uvinul A Plus], Terephthalylidene Dicamphor Sulfonic Acid [Mexoryl SX]).
• Protection Standard: SPF 50+ (protection against UVB rays, which cause burning) and PA++++ (highest level of protection against UVA rays, which cause aging and hyperpigmentation). Both ratings are based on official tests conducted under Korean regulatory standards (MFDS).
• The "Two-Finger" Rule: For adequate protection, dispense sunscreen along the length of your index and middle fingers. This is the correct amount for your face and neck. Using less will significantly reduce the stated SPF level.
• White Cast: Zero white cast. Its lightweight formula blends invisibly into all skin tones, from the fairest to the deepest.
• Water Resistance: The brand states the formula is water-resistant, making it suitable for daily activities and humid weather. However, for prolonged swimming or heavy sweating, reapplication is crucial.
• Reapplication Rules: Reapply at least every 2-3 hours when in direct sun. You must reapply immediately after swimming, towelling off, or heavy sweating. For office days, a single generous morning application is sufficient if you are not sitting by a window.

Daily Use — AM Only:

• Amount: Use the "Two-Finger Rule." Squeeze a line of sunscreen onto your index and middle fingers from base to tip. This is the scientifically tested amount needed for the face and neck to achieve the SPF 50+ rating.
• Apply to: Face, neck, and ears as the very last step of your skincare routine, 15 minutes before sun exposure.
• Method: Smooth gently over the skin and pat lightly to help absorption. Do not rub excessively.
• Frequency: Every single morning, regardless of the weather. UV rays penetrate clouds and windows.

If-This / Then-That:

• Very oily T-zone? This sunscreen's lightweight texture may be hydrating enough for you to skip a separate morning moisturiser.
• Under makeup? Wait 1-2 minutes for the sunscreen to set completely before applying primer or foundation. This dramatically reduces the chance of pilling.
• Sensitive or stinging eyes? While many users report no stinging, chemical sunscreens can sometimes cause sensitivity. Apply carefully around the orbital bone, avoiding the lash line.

Watchouts (1 line): Pilling = too much product underneath or not waiting long enough; Stinging = potential sensitivity to a specific UV filter; "No results" = sun protection is about prevention, the result is less sun damage over years!

Safety: For external use only. Avoid broken or irritated skin. Stop use if a rash or burning occurs. Teens should focus on a simple routine: cleanser–moisturiser–sunscreen.

• Immediately: Your skin is protected from approximately 98% of UVB rays and has the highest level of UVA protection. The skin will feel hydrated with a natural, non-greasy finish.
• 2–4 weeks: With consistent daily use, you are actively preventing the formation of new sun spots, fine lines, and collagen degradation. If you are using brightening products, this sunscreen will protect your progress and help them work more effectively.
• 4–8+ weeks: The benefits are cumulative. Consistent sun protection is the single most effective action against premature aging. Over months and years, your skin will show fewer signs of sun damage (like wrinkles and dark spots) compared to unprotected skin.

• Why use this, not rely on makeup with SPF? The amount of foundation or BB cream needed to achieve the stated SPF is far more than anyone would comfortably wear. Lab-tested sunscreens like this one are designed to be applied generously as your primary, dedicated layer of protection. Makeup with SPF is a great top-up, but not a substitute.
• Why use this, not DIY sunscreen? Do not attempt to make your own sunscreen with coconut oil or zinc powder. SPF ratings are determined through rigorous, standardized lab testing to ensure reliable protection. DIY concoctions offer no guaranteed protection and create a false sense of security, leading to severe sun damage.
• Why use this, even if you have a deep skin tone? Melanin offers some natural protection (around SPF 13), but it is not enough to prevent sun damage, hyperpigmentation (dark spots), and skin cancer. All skin tones need sunscreen. This formula is ideal because it leaves absolutely no white or grey cast.

• Works with: This sunscreen layers well over most skincare products, including Vitamin C serums, niacinamide, and hyaluronic acid. It should always be the LAST step in your morning routine.
• Use carefully with: Heavy, oil-based moisturisers. Applying this sunscreen over a very thick or oily cream without letting it absorb fully may lead to pilling. Allow at least 5-10 minutes after a heavy cream before applying sunscreen.
• Avoid on [Area]: Avoid direct application to the lash line or mobile eyelid if you have very sensitive eyes, as some individuals may experience stinging from chemical filters.

• Oily & Combination Skin: Excellent. Its lightweight, non-greasy formula absorbs quickly and provides hydration without adding shine. It may be hydrating enough to replace a separate AM moisturiser.
• Normal Skin: Excellent. Provides comfortable hydration and protection with a natural finish.
• Dry Skin: Good, but may not be sufficient on its own. It's recommended to layer this over your preferred moisturiser to ensure adequate hydration throughout the day.
• Sensitive & Acne-Prone Skin: Generally good, as it is fragrance-free and non-comedogenic. However, as with any chemical sunscreen, a patch test is highly advised, as some individuals can be sensitive to specific UV filters.

• Sun Protection: Provides robust, broad-spectrum defense against both UVA (aging) and UVB (burning) rays.
• Prevention of Premature Aging: By blocking UV radiation, it helps prevent the breakdown of collagen, which leads to fine lines, wrinkles, and loss of firmness.
• Prevention of Hyperpigmentation: Helps prevent the formation of sun spots, melasma, and the darkening of post-acne marks (PIH).
• Skin Dehydration: Contains hydrating ingredients like Aloe and Sodium Hyaluronate to help maintain the skin's moisture balance during sun exposure.

Safety for Teens: Sunscreen is a crucial and safe step for teenagers. This lightweight formula is a great option to encourage daily use without worries about breakouts or a heavy feel.

• Texture: A watery, gel-lotion that feels exceptionally lightweight and spreads with no effort.
• Finish: A natural, satin finish. It is not overly dewy or completely matte, leaving a healthy-looking glow without feeling greasy.
• Scent: Fragrance-free, with no discernible smell.
• pH: Not publicly disclosed by the brand, but sunscreens are typically formulated in a range that ensures the stability and efficacy of the UV filters.
• Fungal Acne (Malassezia) Compatibility: This formula is generally considered fungal acne-safe. Our review of the INCI list did not find common triggers like polysorbates or fatty acid esters. However, individual responses can vary.

• Issue: The sunscreen is pilling or balling up.
  Quick Fix: This is almost always caused by applying too much product underneath or not allowing previous layers to fully absorb. Simplify your morning routine, use smaller amounts of your serum/moisturiser, and wait at least 1-2 minutes before applying the sunscreen. Apply the sunscreen by patting, not rubbing.
• Issue: My eyes are stinging after application.
  Quick Fix: This can happen with chemical sunscreens. Avoid applying the product directly on your eyelids or too close to your lash line. Apply it around the orbital bone instead. If stinging persists, you may be sensitive to one of the filters and should consider a mineral-based sunscreen.
• Issue: My skin feels a bit shiny by the end of the day.
  Quick Fix: This sunscreen provides a natural, not matte, finish. If you have very oily skin, you can set the sunscreen with a light dusting of translucent powder, like the INNISFREE No Sebum Mineral Powder, on your T-zone.

• Humid Summer: This sunscreen is perfectly suited for our hot and humid summers. Its ultra-light, non-sticky texture feels comfortable and breathable, providing high protection without feeling like a heavy layer on the skin. Oily skin types might find it hydrating enough to use without a separate moisturiser in the morning.
• Drier Winter: During the cooler, drier months, this sunscreen still works beautifully. However, if your skin leans dry, you will likely want to apply it over your regular daily moisturiser to ensure your skin stays hydrated and comfortable all day long.
• Indoors/AC: If you spend most of your day in an air-conditioned office, this sunscreen provides enough hydration for normal to oily skin types. Dry skin types should layer a moisturiser underneath to combat the drying effects of AC.

• Storage: Store in a cool, dark place away from direct sunlight and extreme heat (like a car dashboard) to maintain the stability of the UV filters. A bedroom drawer is ideal.
• Travel: The 50ml size is travel-friendly and suitable for carry-on luggage. The cap is secure and unlikely to leak.

Here’s a balanced look at what real users are saying about this sunscreen. (Aggregated sentiment; individual results may vary).

"The COSRX Ultra Light Invisible Sunscreen truly lives up to its name, offering a feather-light application that's perfect for daily use. Its fluid cream-like texture glides on effortlessly, absorbing quickly... it strikes a beautiful balance - hydrating without being overly rich or greasy."

"Love how lightweight this sunscreen is. Kudos to Cosrx for finally introducing a sunscreen for oily and combination skin. Although the size and quantity is less compared to the price but hey it fits in the bag perfectly."

Fair Caveat: "I use a generous amount... It pills really badly ;-; ... Don't think I recommend this that much because of the pilling."

Will this sunscreen make my oily skin look greasier?
No, it's designed to be lightweight with a natural, non-greasy finish. Most users with oily skin find it very comfortable and not overly shiny.

Can I use this if I have acne?
Yes, the formula is non-comedogenic, meaning it won't clog pores. It also contains soothing ingredients like Aloe and Witch Hazel. However, if your skin is very irritated or you have active, open blemishes, perform a patch test first.

Is it safe to use during pregnancy?
The ingredients in this chemical sunscreen are generally considered safe for topical use during pregnancy. However, some individuals prefer to use mineral-only sunscreens during this time. We recommend consulting with your doctor to make the best choice for you.

Why does it contain Witch Hazel? Isn't that drying?
This product uses Witch Hazel Leaf Water, which is a gentler, distilled form compared to alcohol-based witch hazel extracts. In this formulation, it acts as a soothing and mildly astringent ingredient and is balanced by hydrating components, so it is not drying.
