Glutathione Sunscreen: What the Label Shows and What the Studies Tested
Glutathione has made it into Korean sunscreen. On 30 September 2026, Abib’s glutathione CC sunscreen, sold as a toning tube, was 41st in Olive Young Korea’s sun care sales ranking.[1] Glutathione “is a tripeptide consisting of cysteine, glycine, and glutamate and functions as a major antioxidant.” Your body makes its own.[2] A 2025 systematic review lists “under-eye creams, face masks, sunscreens, and moisturizers” among the products social media has made it popular in, then adds: “Despite its popularity, scientific research on topical glutathione is limited.”[3] So what does a glutathione sunscreen actually give you? We read two glutathione sunscreen labels and the glutathione research to find out.
The short version: On Abib’s Korean page, glutathione is the 40th of 54 ingredients, listed after titanium dioxide (4th) and three iron oxides.[4] Its Korean ingredient list prints glutathione at 0.015%, marked with an asterisk the page doesn’t explain, while its English list gives no amount.[4] APLB’s current retail listing gives none either, and INCIDecoder’s 2023 upload of that same APLB formula shows 10 ppm, which is 0.001%.[5][6] The glutathione studies we read used 0.1% to 2% topical glutathione.[2][3][9] Reviews call the evidence limited, and the Philippine FDA has warned about glutathione injections and about an unauthorized glutathione cream sold with SPF 30.[11][12]
What a glutathione sunscreen label shows
Abib’s Korean page lists the Glutathiosome CC Sunscreen Toning Tube as a triple functional cosmetic, for UV protection, whitening and wrinkle care, first released on 11 March 2025.[4] The page explains its name as “Glutathiosome* = Glutathione + Exosome” and says the formula helps deliver 98%-pure glutathione into skin to help with dark spots, with a footnote limiting that claim to the raw ingredient’s properties.[4] It also reports a 19.77% drop in melanin (pigmentation, melasma and dark spots) after two weeks of use, from a test a Korean testing company ran on 21 people between 7 and 22 January 2025, adding that individual results differ.[4]
The ingredient list on the same page has 54 entries. Titanium dioxide is 4th, niacinamide 9th, and three iron oxides come 27th, 37th and 39th. Glutathione is 40th.[4] The English list gives no amount, but the Korean list on the same page prints glutathione as 0.015%, followed by an asterisk.[4] The page doesn’t explain the asterisk, which also appears next to water, butylene glycol and three other ingredients, so it doesn’t say whether 0.015% is the amount in the finished tube.
APLB’s Glutathione Niacinamide Sunscreen is named in four of the six Google US results we read for glutathione sunscreen on 30 September 2026. An online retailer’s listing, last updated on 30 September 2026, puts glutathione 37th of 50 ingredients and gives no amount.[5] INCIDecoder has a 2023 upload of that same formula, ingredient for ingredient, and its list shows glutathione as “Glutathione (10Ppm)” and niacinamide as “Niacinamide (20,000Ppm)”.[6] Ten parts per million is 0.001%. Twenty thousand parts per million is 2%. INCIDecoder also has a 2025 upload of a newer APLB formula with different UV filters, and that list gives no glutathione amount.[7]
What the glutathione studies tested
The glutathione research we read looked like this:
| Trial | Glutathione used | Control | Reported result |
|---|---|---|---|
| 2014 trial, 30 healthy women aged 30 to 50, 10 weeks[2] | 2% oxidized glutathione lotion, twice daily, on half the face | A placebo lotion on the other side | The melanin index was “significantly lower” on the glutathione side, with “no marked adverse effects” |
| 2021 trial, 46 people, 8 weeks[8] | Topical glutathione on one side of the face, plus glutathione or placebo taken by mouth | Topical placebo on the other side | Topical and oral glutathione both lightened skin, and the combination “might be superior” to either alone |
| Reported in a 2025 review[9] | Topical glutathione at 0.5% | 0.1% glutathione and placebo | 0.5% was “significantly more effective” |
| A trial summarized in the 2025 topical glutathione review[3] | 2% S-acyl glutathione cream | Not stated in the review’s summary | Less redness after UV exposure |
The two trials whose abstracts describe the setup used a lotion and a topical preparation on half the face. Neither is described as a sunscreen.[2][8] The strengths that come up in this research run from 0.1% to 2%.[2][3][9] Taking the printed figures at face value, Abib’s 0.015% is 150 ppm. The 0.5% that beat 0.1% and placebo is about 33 times that, and the 2% lotion about 133 times. The 10 ppm in INCIDecoder’s 2023 APLB upload is 500 and 2,000 times below those two strengths.[4][6] These comparisons are ours, and they only hold if each figure is the amount in the finished product.
What the reviews conclude
- The 2025 review of topical glutathione found five clinical trials that met its criteria. It reported: “A 2% oxidized glutathione lotion decreased the melanin index (p<0.05), total epidermal water loss (TEWL) (p<0.05), and wrinkles (p<0.01).” It also said: “Safety data is limited and warrants further exploration.”[3]
- A second 2025 review, on glutathione for skin lightening and melasma, concluded: “Topical versus oral glutathione both provide moderately efficacious skin-lightening outcomes that are localized versus generalized and have minimal versus substantial adverse effects, but they are unsustainable, with variable costs.”[9]
- A 2016 review went further: “The hype around its depigmentary properties may be a marketing gimmick of pharma-cosmeceutical companies.”[10]
The first review also raised a point the product pages don’t: “Additionally, ethical considerations regarding its use as a skin-bleaching agent must be addressed to avoid reinforcing structural racism and healthcare disparities.”[3]
The glutathione products regulators have warned about
Glutathione isn’t only sold in creams. In 2019, the Philippine Food and Drug Administration warned the public “on the dangers associated with the use of injectable lightening agents such as glutathione.” It noted: “The FDA has not approved any injectable products for skin lightening.” It listed side effects that “include toxic effects on the liver, kidneys, and nervous system.”[11] The 2025 melasma review is blunter: “IV glutathione is contraindicated due to lack of efficacy and side effects.”[9] A 2026 review of the intravenous route found the evidence “too limited to justify routine use for cosmetic skin lightening” and called for larger trials and longer safety studies.[13]
Sunscreen has turned up in these warnings too. In 2025, the same agency told the public not to buy or use a product called “ACTIVE WHITE L- GLUTATHIONE CREAM WITH SUN BLOCK SPF 30” because it had not been issued a product notification as of 4 September 2025.[12] Because the product skipped that process, the agency said it “cannot assure their quality and safety” and warned: “Potential hazards may come from ingredients that are not allowed to be part of a cosmetic product or from the contamination of heavy metals.”[12]
How to read a glutathione sunscreen label
- Find glutathione’s place in the list. It’s 40th of 54 on Abib’s page and 37th of 50 on the APLB retail listing we read.[4][5]
- Look for an amount, in every language on the page. Abib’s 0.015% is in its Korean ingredient list, not the English one.[4] When a list does give an amount, like that 0.015% or the “Glutathione (10Ppm)” line in INCIDecoder’s 2023 APLB upload, you can set it against the 0.1% to 2% used in studies.[6]
- Notice the tint ingredients. In Abib’s CC formula, titanium dioxide and three iron oxides all come before glutathione.[4] Our Korean tinted sunscreen guide covers tinted formulas.
- Ask which ingredient carries a whitening claim. Abib’s page calls the tube a triple functional cosmetic but doesn’t name the ingredient behind the whitening part.[4] For a Korean label that does spell it out, see our look at tranexamic acid sunscreen, which also covers what melasma experts say about sunscreen itself.
- Buy products you can trace. The Philippine warning was about a glutathione cream with SPF 30 that hadn’t been notified to regulators.[12]

FAQ
Does glutathione in sunscreen lighten skin?
Our PubMed search turned up no study that put glutathione inside a sunscreen and tested it. Some trials of topical glutathione, at strengths up to 2%, reported lighter skin, while reviews call the research limited. Of the current labels we read, only Abib’s Korean ingredient list prints an amount, 0.015%.
How much glutathione is in a glutathione sunscreen?
Abib’s Korean ingredient list prints 0.015%, with an asterisk the page doesn’t explain, while its English list and APLB’s current retail listing give no amount. INCIDecoder’s 2023 upload of one APLB formula, still on sale, lists glutathione at 10 ppm, which is 0.001%.
Is glutathione sunscreen safe?
The 2014 trial of a 2% glutathione lotion reported no marked adverse effects, but a 2025 review says safety data is limited. The Philippine FDA has warned about glutathione injections and about an unauthorized glutathione cream sold with SPF 30.
Is glutathione in sunscreen the same as glutathione injections?
No. Injections go into the bloodstream, and the Philippine FDA says it hasn’t approved any injectable product for skin lightening. A 2025 review calls intravenous glutathione contraindicated because of a lack of efficacy and side effects.
