How to use

HOW TO USE
1

Dispense Proper Amount

Use approximately 2 finger-lengths (1/4 teaspoon) for face and neck. This amount is crucial for achieving the labeled SPF protection.

2

Apply Evenly

Dot product across forehead, cheeks, nose, and chin. Gently spread and pat until fully absorbed. Don't forget ears and hairline.

3

Wait Before Sun Exposure

Allow 15-20 minutes for the sunscreen to form a protective film before going outdoors for optimal protection.

4

Reapply Regularly

Reapply every 2-3 hours during sun exposure, or immediately after swimming, sweating, or towel-drying.

06

Frequently asked questions

FAQ

Use with caution. This sunscreen contains chemical UV filters including Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX) and Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus), which have limited safety data for pregnant or nursing women. While these filters have low skin penetration, we recommend consulting with your healthcare provider before use during pregnancy or breastfeeding. For a safer alternative, consider mineral sunscreens with zinc oxide or titanium dioxide.

No, this sunscreen is NOT fungal acne safe. It contains several ingredients that can feed malassezia yeast and trigger fungal acne flare-ups, including: Polyglyceryl-3 Distearate, Palmitic Acid, Stearic Acid, Polyglyceryl-10 Myristate, and Sphingomonas Ferment Extract. If you have fungal acne, look for alternatives like the Purito Centella Green Level Unscented Sun or products specifically labeled as FA-safe.

Yes! In fact, using sunscreen is essential when using these actives. Apply your retinol, vitamin C, or exfoliating acids in your evening routine (retinol) or morning routine (vitamin C), then apply this sunscreen as the final step before makeup. The niacinamide in this formula pairs excellently with vitamin C and can enhance the brightening effects. Always ensure proper sun protection when using photosensitizing ingredients like retinol and AHAs/BHAs.

This sunscreen is best suited for oily, combination, and normal skin types. Its lightweight, fluid texture absorbs quickly without leaving a greasy residue, and the niacinamide helps control sebum production throughout the day. Those with dry skin can use it but may need an additional moisturizer underneath. It's also excellent for acne-prone skin (except fungal acne) and those dealing with post-acne hyperpigmentation thanks to the onion extract and niacinamide.

You'll notice immediate results in terms of UV protection and skin finish (dewy glow). For skincare benefits: oil control improvements typically appear within 1-2 weeks; brightening and improved skin texture within 4-6 weeks; and visible fading of acne scars and hyperpigmentation within 8-12 weeks of consistent daily use. The key is applying it every single day, even when not going outdoors, as UV rays penetrate through windows.

Sunscreen should always be the LAST step of your skincare routine, applied after all serums and moisturizers. The order should be: Cleanser → Toner → Essence/Serum → Moisturizer → Sunscreen. Wait about 1-2 minutes between moisturizer and sunscreen to allow absorption. Apply sunscreen at least 15 minutes before sun exposure. If wearing makeup, apply it after the sunscreen has fully absorbed (about 5-10 minutes).

This sunscreen has a low comedogenic rating of 1/5, meaning it's very unlikely to clog pores for most people. The formula avoids heavy oils and comedogenic silicones. In fact, many users with acne-prone skin report that it doesn't cause breakouts and the niacinamide actually helps keep pores clear. However, if you're prone to fungal acne specifically, avoid this product as it contains ingredients that can trigger malassezia-related breakouts.

The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal efficacy and safety. However, if you're using the recommended amount (2 finger-lengths for face and neck daily), a 50ml tube typically lasts about 4-6 weeks with daily use. Store in a cool, dry place away from direct sunlight and high temperatures to maintain product stability and prevent degradation of the UV filters.

No! Despite containing onion extract, this sunscreen does NOT smell like onions at all. The onion bulb extract is purified and processed to remove any odor while retaining its beneficial properties. Users describe the scent as subtle and fresh, with a light, pleasant fragrance that dissipates quickly after application.

No white cast! This is a purely chemical (organic) sunscreen that uses modern UV filters which absorb into the skin without leaving any visible residue. It's suitable for all skin tones, including deeper complexions. The finish is transparent with a natural dewy glow, making it perfect for everyday wear and as a makeup base.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: The Isntree Onion Fresh Fluid Sun Cream SPF 50+ is an excellent choice for those seeking a lightweight, high-protection sunscreen with added skincare benefits. Its unique Muan Red Onion Extract offers promising scar-fading properties, while niacinamide and modern UV filters provide comprehensive protection and skin brightening. The dewy finish and fast absorption make it ideal for oily to combination skin and a perfect makeup base. However, it's not suitable for those with fungal acne or very sensitive skin. For the price point, you get premium K-beauty technology with photostable, reef-safe filters—a solid daily driver for anyone prioritizing both protection and skin improvement.

lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
