How to read ingredient labels on cosmetics
Here are a few key things to keep in mind when taking a peek at those ingredient lists.
Decoding common terminology
Understanding beauty terms helps you filter marketing fluff from facts and take charge of your routine. Words like active, dermatologically tested, or hypoallergenic often appear, but what do they mean?
- Active ingredients are those that directly target concerns such as brightening, exfoliation, or hydration.
- Dermatologically tested means it’s been tested on skin, but doesn’t guarantee it suits everyone.
- Fragrance-free vs. unscented: fragrance-free means no added scent chemicals; unscented may include masking agents to hide a smell. That fragrance distinction is especially important when identifying ingredients that can trigger irritation.
Regulatory standards and labeling guidelines
In South Africa, cosmetics should include a full INCI list (International Nomenclature of Cosmetic Ingredients). This standardised naming system improves transparency and makes it easier to check ingredients against reputable safety references.
Tip: Look for a complete INCI name list on packaging, not just marketing terms like “natural” or “organic.” Even “natural” formulas can include irritating ingredients if they’re poorly preserved.
Order of ingredients: what it means
Ingredients appear in descending order by concentration. The first few ingredients usually make up most of the formula—so they matter most for performance (and for potential irritation).
- If glycerin or hyaluronic acid sits near the top, you’re likely looking at a hydrating formula.
- If alcohol denat or strong solvents lead the list, it may feel drying—especially for dry or reactive skin.
- Scan for potential irritants early in the list to spot “red flags” fast.
Decoding common ingredients and what they do
Let’s explore essential skincare ingredients every skincare enthusiast should recognise, so you can shop smarter and build a routine that supports your skin.
Moisturisers: Glycerin, Hyaluronic Acid, Squalane
Hydration is the foundation of a healthy-looking glow. These ingredients help attract and hold water, and support the skin’s comfort.
- Glycerin — a powerful humectant that draws water into the skin.
- Hyaluronic acid — holds up to 1000x its weight in water; great for dehydrated skin.
- Squalane — mimics skin’s natural oils, balancing moisture without clogging pores.
Acids: AHAs, BHAs, Salicylic Acid
Chemical exfoliants are game-changers—when used correctly. The key is matching the acid type to your skin’s needs and keeping frequency sensible.
- AHAs (glycolic, lactic) — resurface dull, textured skin; often suit normal to dry types.
- BHAs (salicylic acid) — oil-soluble, effective for acne-prone or congested skin.
- Less is more: overuse can weaken your barrier—start slowly and build only if comfortable.
Antioxidants: Vitamin C, Green Tea, Niacinamide
Antioxidants help neutralise free radicals, support the barrier, and boost glow—making them excellent “daily defense” ingredients.
- Vitamin C — brightens and supports firmer-looking skin.
- Green tea extract — soothes and helps defend against inflammation.
- Niacinamide — helps regulate oil and refine the look of texture.
Preservatives + fragrance: what’s “safe”?
Preservatives prevent microbial growth (which protects your skin). Fragrance can be a common irritation trigger—especially for sensitive skin.
- Phenoxyethanol — generally used at low levels (often under 1%).
- Parabens — controversial online, but widely used and effective when regulated.
- Fragrance (parfum) — may hide many compounds; if you’re reactive, choose fragrance-free rather than “unscented.”
Bottom line: “Preservative-free” can sound appealing, but it also increases contamination risk. Look for balance and evidence—not hype.
Tips for spotting red flags
Skincare can be expensive, so it helps to know what to watch for before you spend.
- Overloaded ingredient lists: More isn’t always better. Complex formulas can raise the chance of reactions.
- Drying alcohols near the top: High levels of alcohol denat can compromise the barrier for dry or reactive skin.
- Hidden fragrance: “Parfum,” “fragrance,” or loads of essential oils can trigger redness or itching in sensitive skin.
Pro tip: If your skin is easily irritated, look for shorter formulas, clear disclosure, and “fragrance-free” (not just “unscented”).
