Ingredient breakdown

INGREDIENTS

Polyglutamic Acid Part of 8%Proven

A powerful humectant derived from fermented soybeans (natto) that can hold 4x more moisture than hyaluronic acid. Creates a protective film on skin's surface to prevent water loss.

  • Hydration: Forms a moisture-trapping barrier on skin surface
  • Texture: Delivers smooth, plump appearance
  • Molecular Size: Larger molecules stay on surface for visible hydration
Unlike hyaluronic acid, PGA works on the skin's surface rather than penetrating deeper layers, making it ideal for instant visible hydration.

Octocrylene 10%UV Filter

A photostable UVB filter that also helps stabilize other sun filters like Avobenzone. Provides protection in the UVB range with peak absorption at 304nm.

  • Stability: Loses only 10% SPF protection after 95 minutes
  • Function: Absorbs UVB rays and stabilizes formula
  • Water Resistance: Improves water-resistant properties

Avobenzone 3%UVA Filter

The most widely used UVA filter globally. Provides broad protection against UVA rays that cause aging and hyperpigmentation.

  • UVA Protection: Peak absorption at 357nm
  • Stabilized: Combined with Octocrylene for enhanced photostability

Squalane Part of 8%Proven

A lightweight, non-greasy emollient that mimics skin's natural sebum. Helps lock in moisture without clogging pores.

  • Biocompatible: Naturally found in human sebum
  • Non-Comedogenic: Won't clog pores
  • Protective: Creates a barrier against moisture loss

Purple Tea ExtractAntioxidant

Rich in anthocyanins and polyphenols, purple tea extract provides powerful antioxidant protection against environmental stressors including UV damage and blue light.

  • Antioxidant: Neutralizes free radicals from UV exposure
  • Anti-inflammatory: Helps calm and soothe skin

How to use

HOW TO USE
1

Shake Well

Shake the tube before each use to ensure the formula is properly mixed for even protection.

2

Measure the Right Amount

Apply product to 3 fingers first (about ¾ teaspoon). This ensures adequate coverage for full SPF 30 protection.

3

Apply Generously

Spread evenly across face and neck. Don't forget ears and hairline. Apply 15 minutes before sun exposure.

4

Wait Before Makeup

Allow 60 seconds to absorb fully before applying makeup. The tacky finish will help makeup grip and last longer.

5

Reapply Throughout the Day

Reapply every 2 hours, especially if sweating. Use a beauty sponge to reapply over makeup without disturbing it.

06

SKIN TYPES
Dry Skin
Excellent

8% hydration trio provides intense moisture. Many users skip their moisturizer when using this SPF. Perfect for parched, dehydrated skin.

Combination Skin
Good

Works well but may enhance shine in T-zone by afternoon. Consider setting with translucent powder on oily areas.

Oily Skin

Acne-Prone Skin
Moderate

Low comedogenic rating (1/5) but NOT fungal acne safe. Regular acne-prone skin should be fine; avoid if you have Malassezia issues.

Frequently asked questions

FAQ

Yes, 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.

— Skincarisma verdict
4.3 / 5 ★★★★☆

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.

question
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.
