Ingredient breakdown
INGREDIENTSZinc Oxide ~20-25% (est.)Proven
The star active and only true UV filter in this formula. Zinc oxide is a broad-spectrum mineral filter that physically shields skin from UVB, UVAII and UVAI. Amaterasun uses a new-generation grade that "melts" into skin to minimize white cast.
- FDA: One of only two recognized mineral UV filters and the broadest UVA/UVB reflector approved.
- Photostability: Highly photostable, so it does not degrade quickly under sunlight.
- Soothing: Has skin-protectant and soothing properties; unlikely to sting eyes, making it ideal for sensitive skin and children.
Butyloctyl Salicylate ~2-5% (typical)Promising
A photostabilizer and SPF booster that helps the zinc oxide perform better and spread evenly. Although structurally related to octisalate, here it acts as an emollient and stabilizer rather than a standalone sunscreen agent.
- Function: Stabilizes UV filters and helps prevent them from degrading too quickly.
- Manufacturer note: Specifically suited for pairing with micro zinc oxide, titanium dioxide and pigments.
Houttuynia Cordata (Heartleaf) Extract SoothingPromising
Also known as Fish Mint or Chameleon plant, Heartleaf is a hero soothing botanical rich in flavonoids and polysaccharides that calm and hydrate stressed skin.
- Antioxidant: Flavonoids such as quercetin help neutralize free radicals.
- Soothing: Anti-inflammatory and antimicrobial properties help calm reactive, redness-prone skin.
Dipotassium Glycyrrhizate SoothingPromising
A licorice-root derivative valued for calming and brightening. It is a gentle, well-tolerated soothing agent that pairs naturally with a sensitive-skin sunscreen.
- Anti-inflammatory: Licorice extracts show antibacterial, anti-inflammatory and antioxidant activity.
- Brightening: Compounds like glabridin have been shown to help block UVB-induced pigmentation in studies.
Tocopherol (Vitamin E) ~0.5-1%Proven
A classic fat-soluble antioxidant that protects the skin from free radicals and strengthens the lipid barrier — a great companion to sun protection.
- Barrier support: Helps keep natural skin lipids and ceramides healthy.
- UV synergy: Helps reduce UVB-induced damage, especially when paired with antioxidants.
Ethyl Ferulate + Rosemary Leaf Extract AntioxidantsPromising
A duo of plant-derived antioxidants. Ethyl ferulate (a ferulic-acid derivative) is commonly used in mineral sunscreens, while rosemary leaf extract adds rosmarinic and caffeic acids.
- Ethyl Ferulate: Typically used at 0.5-1%; supports the antioxidant defense of the formula.
- Rosemary Extract: Rich in antioxidants that help soothe and protect against environmental stress.

Where it fits in your routine
ROUTINEAlways the final step of your morning skincare. Apply after moisturizer (and before makeup) as the outermost protective layer, 15 minutes before sun exposure.
How to use
HOW TO USEUse Enough Product
Dispense roughly two finger-lengths to cover the whole face evenly — this is what achieves the labeled SPF 50+.
Apply as the Last Skincare Step
Smooth over the face after your skincare routine and before makeup. Blend thoroughly to settle any initial cast.
Wait Before Sun Exposure
Apply 15 minutes before heading outdoors so the film can set for full protection.
Reapply Every 2 Hours
Reapply at least every 2 hours during sun exposure, and more often after sweating or swimming.

- You prefer a 100% mineral / chemical-filter-free sunscreen

- You are pregnant or breastfeeding and want a mineral option
Consider alternatives if:

Skin type compatibility
SKIN TYPESPure mineral filter, fragrance-free and soothing Heartleaf make this a standout for reactive skin.
The emollient, slightly dewy finish suits dry skin well and helps the formula sit comfortably.
Comfortable for most, though the dewy finish may need a light powder over oilier zones.
Some oily-skin users find the finish slightly greasy. A mattifying primer or powder helps.
Many users report it does not aggravate acne, but it is not fungal-acne safe — patch test first.

Budget-friendly alternatives (dupes)
DUPESAnother mineral-leaning Indonesian SPF 50+ with barrier-support ingredients like ceramides and hyaluronic acid. Lighter gel feel, but a different soothing profile.
Extremely affordable Indonesian favorite with a watery gel texture and no white cast. Uses hybrid filters rather than 100% mineral, so less suited to strict mineral users.
A vegan Korean mineral sun cream that, per SkinSort, shares a comparable physical-filter approach. Slightly higher price and a heavier finish.

Frequently asked questions
FAQGenerally, yes. It is a 100% mineral sunscreen built on zinc oxide, with no oxybenzone, no avobenzone, no retinoids and no hydroquinone — the kind of profile most dermatologists recommend during pregnancy and breastfeeding. As always, confirm with your own doctor for your specific situation.
No. The formula contains several ingredients that may feed malassezia yeast, including polyglyceryl esters, isopropyl myristate, ethylhexyl palmitate, isostearic acid, sunflower seed oil and lecithin. If you are prone to fungal acne, this is best avoided in favor of a fungal-acne-safe mineral sunscreen.
Yes. Sunscreen is the final morning step and layers fine over actives applied earlier. In fact, daily SPF is essential when using retinol, vitamin C, AHA or BHA because those ingredients can increase sun sensitivity. Use your actives first, let them absorb, then apply this sunscreen last.
It performs best on sensitive, dry, normal and combination skin thanks to its fragrance-free, soothing mineral formula. Oily-skin users may find the finish a touch dewy and can set it with powder. It is also gentle enough for children from age 1.
Sun protection is immediate — mineral filters work as soon as the product is applied and set (apply 15 minutes before sun exposure). Soothing and comfort benefits appear with first use, while the anti-aging payoff of preventing dark spots and wrinkles comes from consistent daily use over months and years.
It is always the last step of your morning skincare. Apply it after cleanser, toner, serum and moisturizer — and before makeup. Allow your other products to absorb fully first to avoid pilling.
It rates around 2 out of 5 for comedogenicity — low to moderate. It contains a few esters (such as isopropyl myristate and ethylhexyl palmitate) and sunflower oil that can be richer for some, but many acne-prone users report it does not break them out. If your skin is easily congested, patch test first.
Around 12 months after opening (12M PAO). Store it in a cool, dry place away from heat and direct sunlight, and replace it once it changes in color, smell or texture.
Verdict: Amaterasun Physical Sunscreen SPF 50+ PA++++ is a standout value in the mineral sunscreen category. It delivers genuine 100% zinc-oxide broad-spectrum protection with soothing Heartleaf, a fragrance- and alcohol-free formula, and impressively little white cast for a physical filter — all at a remarkably low price and gentle enough for children from age 1. The trade-offs are a slightly thick texture that needs blending, a dewy finish that can read greasy on very oily skin, and the fact that it is not fungal-acne safe. For sensitive, dry or normal skin (and budget-conscious mineral-sunscreen fans), it is an easy recommendation.
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.
