IFRA: fragrance safety
The Library·Decode the Label IFRA (International Fragrance Association) publishes safety standards for fragrance ingredients, maximum safe concentrations, banned materials, restricted uses. Perfumers and cosmetic manufacturers worldwide formulate against IFRA standards. What “IFRA compliant” means: the fragrance in the product stays within internationally agreed safety limits for skin contact. Relevant for perfumes obviously, but also for anything scented that sits on your skin. What it doesn’t mean: IFRA compliance doesn’t mean a fragrance won’t irritate your skin specifically. Fragrance remains one of the most common causes of cosmetic skin reactions even... Read more...
SPF & the ISO sunscreen standards (ISO 24444, 24442, 24443)
The Library·Decode the Label SPF is not a vibe. It’s a measured number, and there are international standards for how to measure it. ISO 24444, the in-vivo test for SPF (UVB protection), measured on real human volunteers ISO 24442, the in-vivo test for UVA protection ISO 24443, the in-vitro (lab instrument) method for UVA protection, used for the “PA+” and “broad spectrum” claims Why it matters: anyone can print “SPF 50” on a tube. The question is whether the number came from an actual ISO-standard test at an accredited lab,... Read more...
GMP: Good Manufacturing Practices
The Library·Decode the Label GMP is a set of standards for how a product is made: clean facilities, trained staff, batch records, quality control at every step, contamination prevention. It’s about the factory, not the formula. Why it matters: you can have a beautiful formula ruined by a dirty production line. GMP compliance means the product you buy in March is the same as the one made in January, and neither one grew anything it shouldn’t have. For products that go on your face daily, this is quietly one of... Read more...
PCSIR: Pakistan Council of Scientific & Industrial Research
The Library·Decode the Label PCSIR is a government research organisation with testing laboratories across Pakistan. Brands send products to PCSIR labs for independent analysis: microbial safety, heavy metal content, composition verification, stability. What it means on a beauty product: “PCSIR tested” means the brand paid for independent lab analysis rather than relying only on their own claims. Ask what was tested - a microbial safety report and a full composition analysis are different things. Why it matters: for small local brands without international certifications, a PCSIR test report is often... Read more...
PSQCA: Pakistan Standards and Quality Control Authority
The Library·Decode the Label PSQCA is Pakistan’s national standards body. It writes Pakistan Standards (PS): technical specifications for how products should be made, and certifies products against them. What it means on a beauty product: several cosmetic categories (skin creams and lotions, shampoos, soaps among them) fall under PSQCA’s mandatory certification regime. A product carrying the PS mark has been tested against the relevant Pakistan Standard: composition limits, safety parameters, labelling requirements. Why it matters: it’s the closest thing general cosmetics have to a “this was checked” stamp in Pakistan.... Read more...
Claims that sound official but aren't regulated
The Library·Decode the Label These phrases appear on packaging everywhere. None of them has a legal definition in Pakistan. That doesn’t automatically make them lies, it makes them unverifiable unless the brand shows its work. “Dermatologically tested”, means a dermatologist was involved in some test. “Non-comedogenic”, means “shouldn’t clog pores.” “Hypoallergenic”, no legal definition anywhere, including the US and EU. Means “we think this is less likely to cause reactions. “Clean” / “natural” / “chemical-free”, meaningless. Everything is chemicals, including water. “Natural” isn’t safer (poison ivy is natural) and “synthetic”... Read more...
INCI: the ingredient list
The Library·Decode the Label INCI (International Nomenclature of Cosmetic Ingredients) is the standardised global naming system for cosmetic ingredients. It’s why glycerin is “Glycerin” on a Pakistani label, a Korean label, and a French one. How to read one: Ingredients are listed in descending order of concentration - until you hit 1%, after which they can appear in any order The first five ingredients are usually most of the product “Aqua” first is normal. Water is the base of most skincare. An active listed dead last, after the fragrance, is... Read more...
Azelaic Acid
The Library·Ingredients A–Z the quiet multitasker - acne, rosacea, redness, and pigmentation, with sensitivity-friendly manners. Criminally underrated. What it actually does: kills acne bacteria, calms inflammation, gently normalises cell turnover, and inhibits pigment production - but selectively, targeting overactive pigment cells. That selectivity makes it a favourite for melasma and post-inflammatory marks on brown skin. Who it’s for: acne-prone skin that finds benzoyl peroxide too harsh, redness-prone and rosacea-prone skin, and anyone fighting dark marks. It’s also pregnancy-safe, which almost nothing else on this page is. How to use it:... Read more...
Lactic Acid (AHA)
The Library·Ingredients A–Z glycolic’s gentler sibling - exfoliates and hydrates at the same time, the right first acid for most people. What it actually does: a larger AHA molecule that works more at the surface, so less irritation for slightly slower results. Uniquely, it’s also a humectant - it exfoliates while pulling water in, which no other common acid does. Who it’s for: first-time acid users, dry or sensitive skin that still wants exfoliation, dullness, mild texture. How to use it: 5–10%, at night, once or twice a week to... Read more...
Glycolic Acid (AHA)
The Library·Ingredients A–Z the strongest common AHA - resurfaces texture and fades marks fast, and punishes impatience just as fast. What it actually does: the smallest AHA molecule, so it penetrates deepest. Dissolves the glue between dead surface cells for smoother texture, better glow, and gradual fading of pigmentation. Long-term use has modest collagen-stimulation evidence too. Who it’s for: dullness, rough texture, post-acne marks, normal-to-oily resilient skin. Not the best first acid for sensitive or dry skin (that’s lactic or a PHA), and darker skin tones should go slower -... Read more...
Retinol & Retinoids
The Library·Ingredients A–Z the most evidence-backed anti-ageing and acne ingredient in existence, and the one most people quit because nobody warned them about weeks two through four. What it actually does: retinoids (vitamin A derivatives) speed up skin cell turnover and stimulate collagen production. The family runs from gentle (retinyl esters) through retinol and retinal (over the counter) to prescription tretinoin and adapalene. Everything else in anti-ageing skincare is auditioning for the role retinoids already have. Who it’s for: fine lines, texture, acne, post-acne marks, general “my skin looked better... Read more...
Vitamin C
The Library·Ingredients A–Z the morning antioxidant. It brightens, defends against UV and pollution damage, and fades pigmentation, if (big if) the formula is stable. What it actually does: L-ascorbic acid neutralises free radicals from sun and smog, is required for collagen synthesis, and inhibits the enzyme that produces excess pigment. It’s the best-evidenced brightening ingredient that isn’t prescription-only. Who it’s for: dullness, sun damage, uneven tone, and anyone playing long-term defence. Given our UV index and our winter air quality, that’s most of us. How to use it: morning, under... Read more...
