How to use
HOW TO USEShake Well
Shake the tube before each use to ensure the formula is properly mixed for even protection.
Measure the Right Amount
Apply product to 3 fingers first (about ¾ teaspoon). This ensures adequate coverage for full SPF 30 protection.
Apply Generously
Spread evenly across face and neck. Don't forget ears and hairline. Apply 15 minutes before sun exposure.
Wait Before Makeup
Allow 60 seconds to absorb fully before applying makeup. The tacky finish will help makeup grip and last longer.
Reapply Throughout the Day
Reapply every 2 hours, especially if sweating. Use a beauty sponge to reapply over makeup without disturbing it.

Ideal balance of hydration and protection. Leaves a healthy, natural glow without feeling heavy or greasy.
Works well but may enhance shine in T-zone by afternoon. Consider setting with translucent powder on oily areas.
Dewy finish may be too much for very oily skin. Works better in cooler months or with mattifying products layered on top.

Frequently asked questions
FAQYes, this sunscreen is confirmed safe for pregnancy and breastfeeding by The INKEY List. It does not contain retinoids, salicylic acid (the UV filter ethylhexyl salicylate is different from beta-hydroxy acid), hydroquinone, or any other ingredients typically flagged during pregnancy. The chemical UV filters used are considered safe for topical use during pregnancy.
No, this sunscreen is NOT fungal acne safe. It contains several ingredients that may feed Malassezia yeast including Saccharomyces Ferment, Lactobacillus Ferment Lysate, Polysorbate 60, Sorbitan Isostearate, Cetearyl Alcohol, and potentially the squalane depending on its source. If you have fungal acne, consider alternatives like Skin Aqua UV Super Moisture Milk or Cotz Face SPF 40.
Yes, this sunscreen works well with all of these actives. In fact, wearing SPF is essential when using retinol, vitamin C, AHAs, or BHAs as these ingredients can increase sun sensitivity. Apply your actives in the evening (retinol) or morning (vitamin C), then apply this sunscreen as the final step. Note: Some users report pilling when layering multiple products - wait 60 seconds between each layer.
This sunscreen is best for dry, dehydrated, and normal skin types. The 8% hydration trio provides intense moisture, and the dewy finish gives a healthy glow. Combination skin can use it but may need powder to set oily areas. Those with very oily skin may find it too dewy, especially in humid conditions. It's also suitable for sensitive skin, including those with eczema or rosacea.
You'll see immediate results in terms of hydration and the dewy finish - 97% of users noticed this instantly. Improved skin texture typically appears within 1-2 weeks of consistent use as the Polyglutamic Acid hydrates your skin. The real benefits of sun protection are cumulative and preventive - you're stopping future damage with every application.
This sunscreen should be the LAST step in your morning skincare routine, after all serums and moisturizers. Apply cleanser → toner → serums → moisturizer (optional, as this SPF is hydrating) → this sunscreen. Wait 60 seconds before applying makeup. In the evening, remove with an oil or balm cleanser like The INKEY List Oat Cleansing Balm.
This sunscreen has a low comedogenic rating of 1/5, meaning it's unlikely to clog pores for most people. It's non-greasy and absorbs well without leaving heavy residue. However, individual reactions vary - if you're acne-prone, do a patch test first. Note: It's not suitable for fungal acne specifically due to yeast-feeding ingredients, even though it won't clog regular pores.
This sunscreen has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight. If you're using it daily with the recommended amount (3 fingers worth), a 50ml tube typically lasts about 4-6 weeks. The recyclable tube should be separated (cap off, cut top) before recycling.
Verdict: The INKEY List Polyglutamic Acid Dewy Sunscreen SPF 30 is an excellent budget-friendly daily sunscreen that delivers on its hydration and dewy finish promises. At just $14.99, it offers exceptional value with its 8% hydration trio, no white cast formula, and primer-like qualities. It's perfect for dry to normal skin types seeking a glass-skin glow. However, the SPF 30 protection (vs SPF 50), lack of water resistance, and fungal acne triggers may be dealbreakers for some. If you have dry skin, want a hydrating SPF that doubles as primer, and are pregnant or breastfeeding, this is an outstanding choice. Those with fungal acne or very oily skin should look elsewhere.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
