If your bathroom shelf is groaning under the weight of serums, acids, peptides, retinoids, moisturisers and masks, you’re not alone.
When did skincare become so complicated? Between 10-step routines, skin cycling, conflicting advice about which actives can be combined and TikTok debates about how long you should wait between layers, even the most committed beauty lover can be left wondering whether they’re doing any of it correctly.
News flash: the problem may not be the products you’ve bought. It may simply be how you’re using them. This has become part of the broader philosophy behind Skin Renewal’s recently launched doctor-developed skincare range - you don’t necessarily need to spend more on skincare; you need to spend more wisely and understand how to get the most from what you're using.
The Order Matters
The basic rule of layering is surprisingly simple: generally, move from the lightest texture to the heaviest. After cleansing, corrective or active serums should generally come first, followed by hydrating serums, moisturiser or barrier-repair products and, in the morning, sunscreen.
There is science behind the sequence. Lightweight products penetrate the skin more easily, while active ingredients such as retinoids, vitamin C, niacinamide, peptides and azelaic acid need good contact with the skin. Richer creams come later because they help create a protective layer and seal everything in. Put that heavier layer on too early, and you may reduce the efficacy and the penetration of the actives.
No, You Don't Need to Wait 20 Minutes
The idea that skincare products need long intervals to ‘sink in’ is a myth. “For most products, there is no need to wait 10, 20 or 30 minutes between layers,” says Skin Renewal’s co-founder and medical director Dr Maureen Allem. “Once a product has been spread evenly and is no longer wet on the surface, you can generally move on to the next step – and that’s usually somewhere between 30 seconds and two minutes.”
A little extra time - around one to two minutes - can be useful after applying a highly active product, such as a retinoid, before following with ceramides or a barrier-repair product. There are other small tweaks that can help too - hydrating ingredients like hyaluronic acid and peptide serums can be applied to slightly damp skin. Skin Renewal’s MD Hydrating Peptide Complex, for example, is designed to boost hydration and works particularly well this way, especially when added as a “buffer” before a retinoid active.
More Doesn’t Mean Better
Perhaps the bigger layering mistake is assuming that if one active is good, three must be better. Retinoids combined aggressively with strong exfoliating acids can compromise the skin barrier. Piling glycolic, salicylic and lactic acids into the same routine is not necessarily going to fast-track results. “The issue is often not incompatibility, but irritation,” explains Dr Maureen. “More activity does not necessarily mean better results.”
Skin Renewal advocates what it calls a combination-therapy philosophy: products chosen to address different pathways while supporting one another rather than overwhelming the skin. A retinoid, for example, can be combined with ceramides as a final layer to support the barrier and improve tolerability. Antioxidants paired with sunscreen help protect against oxidative and UV damage. For pigmentation-prone skin, azelaic acid can be combined with targeted brightening peptides.
The aim isn’t to encourage you to spend more on skincare, but to spend more wisely - investing in hardworking multifunctional products that earn their place in your routine, while leaving room in your skincare budget for the in-clinic treatments that products alone can’t replicate.
Spend Smarter, Not More
The good skincare fundamentals remain consistent and non-negotiable: cleanse, treat appropriately, hydrate, support the barrier and protect the skin from the sun. Corrective products such as retinoids and exfoliating acids can then be adjusted according to tolerance. “The healthiest skin is not the most aggressively treated skin,” says Dr Maureen, “hydration, barrier support and gradual correction will always outperform irritation and over-exfoliation.”
She continues: “Great skincare is not about owning more products. It is about understanding how to use the right products, in the right order, with consistency.” This philosophy is central to why Skin Renewal waited 21 years before launching its own skincare range. Developed after more than two decades of treating skin in clinic, the multifunctional formulations have been designed to work alongside the technologies and treatments used by Skin Renewal’s doctors and therapists.
