Most of the skincare industry is expensive packaging and clever marketing. A small number of ingredients have genuine, peer-reviewed evidence behind them. These are the ones worth spending money on — and the products that deliver them properly.

Paula's Choice 2% BHA Liquid Exfoliant
ExfoliationSalicylic acid is oil-soluble, which means it can penetrate pores where water-based ingredients can't reach. This is the mechanism that makes BHA genuinely effective for blackheads and congestion rather than just marketing language. Paula's Choice delivers it at the right pH for it to actually work, which many cheaper alternatives don't. One of the most consistently well-reviewed skincare products across dermatology communities.
Worth it because
- Right pH for salicylic acid to function
- Fragrance-free, minimal irritants
- Consistent results across skin types
The catch
- Takes 4–6 weeks to see noticeable results
- Premium price for what is essentially one active ingredient
The Ordinary Retinol 0.5% in Squalane
Anti-ageingRetinoids are the most evidence-backed ingredient in skincare for influencing the appearance of fine lines, skin texture and uneven tone. The Ordinary delivers a meaningful 0.5% concentration in a squalane base that buffers irritation — making it a practical starting point before moving to higher concentrations. The price-to-actives ratio is hard to argue with.
Worth it because
- Retinol is one of the best-evidenced skincare actives
- Squalane base reduces irritation
- Exceptional value for the concentration delivered
The catch
- Requires sun protection during use
- Initial purging period of 2–4 weeks is common
La Roche-Posay 10% Pure Vitamin C Serum
BrighteningVitamin C as L-ascorbic acid is the form with the strongest evidence for brightening and antioxidant protection — but it's also the most unstable. La Roche-Posay encapsulates it to slow oxidation, which is why it outperforms cheaper vitamin C serums that start degrading in weeks. 10% is an effective concentration without the irritation that higher percentages cause in most skin types.
Worth it because
- Encapsulated for stability — doesn't oxidise quickly
- Dermatologist-recommended brand with strong safety profile
- Effective concentration without over-irritating
The catch
- Still needs to be stored away from light and heat
- Pricier than unencapsulated alternatives
