“Brands see single-ingredient products as an opportunity to offer more targeted solutions, increase consumer engagement, and build loyalty,” explains Dr Queiroz. “They are easier to market, as the benefit of the product is simple and clear, and consumers can mix and match products to create personalised routines. This approach also allows brands to introduce innovations more quickly by focusing on one ingredient per product.”
Dr Deo notes that multi-active formulas demand extensive compatibility testing, ingredient compromises to maintain stability, and often lower active concentrations. Single-ingredient formulations, by contrast, are more stable, easier to scale, and less prone to degradation.
“Current trends also demonstrate that modern consumers value transparency, ingredient knowledge, and control over their routine, which single-ingredient products align well with,” she states.
When to choose conventional all-in-one skincare
Experts say conventional all-in-one formulas are convenient and practical for beginners, those who prefer a simple skincare routine, or are simply short on time or consistency. They’re especially useful for sensitive skin, offering multiple benefits in a single product without layering too many actives. Such formulas are also ideal when the skin barrier is compromised — inflamed, sensitised, or post-procedure — where fewer steps and barrier-supportive blends help the skin recover.
Single-ingredient routines, by contrast, require a deeper understanding of your skin and patience with trial and error. If you’d rather skip the experimentation, all-in-one formulas remain the safer, more forgiving choice.
The expert’s guide to building a single-ingredient skincare routine
Step 1: identify your primary concern
Focus on one concern at a time. For acne, the experts recommend salicylic acid or benzoyl peroxide. For pigmentation, look at azelaic acid or tranexamic acid. For ageing, retinol or peptides work well. For sensitivity, panthenol or centella are ideal. Once that is clear, look for products with clinically proven concentrations of active ingredients.
“Some molecules have multiple roles; for example, salicylic acid not only helps with oiliness and reducing blackheads but also contributes to skin brightening, and glycolic acid has similar dual effects,” says Dr Queiroz. “With proper assessment, it is possible to choose products in a way that, even using a single ingredient, the treatment is optimised and tailored for each individual.”
Step 2: start with lower concentrations
“Titrate slowly instead of jumping to the strongest,” warns Dr Deo. Begin with mild formulations, especially when choosing acids and retinoids. Increase strength gradually to build tolerance and avoid irritation.
Step 3: check formulation quality
Look for a proper pH, especially for acids and retinol encapsulations. Include supporting ingredients in your routine to reduce irritation. “Consider formulation stability, as some ingredients like vitamin C or retinol require specific packaging, and compatibility with your existing routine to avoid irritation,” advises Dr Queiroz.
Step 4: layer with intention
The rule of thumb? One active per routine. Space strong actives between AM and PM and always introduce new actives one at a time.
Step 5: support with basics
Always support your single-ingredient products with a gentle cleanser, a barrier-repair moisturiser, and a daily sunscreen.
Expert’s Note: It is very important to consult with a dermatologist because certain skin conditions can impact not only the results but also increase the risk of hypersensitivity.
