Personal care
Most skin-care spending is wasted on wrong concentrations, hidden fragrance, or sunscreen that doesn't protect the way you think it does. The label tells you almost everything if you know the order to read it in.
A few questions about your situation, not about the product.
Answer all 4 questions to see the spec sheet to shop with.
SPF measures UVB protection; PA measures UVA protection.
Why it matters
UVB burns; UVA ages and darkens. Broad spectrum is not enough — PA+++ or PA++++ is what matters for daily use.
What to check
SPF 15 moisturisers that claim anti-ageing but give almost no UVA protection.
The percentage of the ingredient that does the work.
Why it matters
Niacinamide works at 2–5%; vitamin C at 10–20%; salicylic acid at 0.5–2%. Below that, you're buying marketing.
What to check
'With retinol' on the front but no percentage on the box.
Ingredients are listed from highest to lowest concentration.
Why it matters
If a hero ingredient is near the end, it's only there for the label claim, not results.
What to check
Fragrance or essential oils hiding in the first half of a sensitive-skin product.
Skin is naturally slightly acidic, around 4.5–5.5.
Why it matters
A high-pH cleanser strips the barrier; an acid toner at the wrong pH either irritates or does nothing.
What to check
'Gentle' cleansers with a pH above 6.5.
Whether the formula is built for oily, dry, sensitive, or acne-prone skin.
Why it matters
A rich cream can break out oily skin; a foaming cleanser can wreck dry skin.
What to check
One-size-fits-all claims when the ingredient list is clearly heavy or fragranced.
Common irritants that can cause redness, sensitivity, or breakouts over time.
Why it matters
'Natural' fragrance from essential oils is still fragrance. Denatured alcohol high up can dry skin out.
What to check
'Unscented' can mean a masking scent was added; 'fragrance-free' is the safer claim.
Test a new product on a small area first, and check the PAO jar symbol.
Why it matters
Actives oxidise and degrade; a retinol bought two years ago may be useless.
What to check
Open jars with no preservatives and no clear period-after-opening date.
A good routine is cleanser + moisturiser + sunscreen. Add actives only after those three are locked in.
