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 belong together and TikTok debates about how long you should wait between layers, even committed beauty lovers might wonder whether they’re doing any of it correctly.
The problem might not be the products you’ve bought. It might be how you’re using them.
This thinking forms part of the 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 the products you already use.
The order of your skincare products matters
The basic rule of skincare layering is surprisingly simple. Generally, work 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.
During your morning routine, sunscreen comes last.
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.
Apply the heavier layer too early and you may reduce the efficacy and penetration of your actives.
You don’t need to wait 20 minutes between products
If you’ve been standing in the bathroom waiting 20 minutes between skincare steps, there is some good news.
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.
Hydrating ingredients such as hyaluronic acid and peptide serums can also be applied to slightly damp skin.
Skin Renewal’s MD Hydrating Peptide Complex, for example, is designed to increase hydration and works particularly well this way, especially when added as a “buffer” before a retinoid active.
More skincare doesn’t mean better results
Another common layering mistake is assuming that if one active is good, three must be better.
Aggressively combining retinoids with strong exfoliating acids can compromise the skin barrier. Adding glycolic, salicylic and lactic acids to the same routine will not necessarily deliver faster results.
“The issue is often not incompatibility, but irritation,” explains Dr Maureen. “More activity does not necessarily mean better results.”
Skin Renewal advocates a combination-therapy philosophy, where products address different pathways while supporting one another rather than overwhelming the skin.
A retinoid, for example, can be paired with ceramides as a final layer to support the skin barrier and improve tolerability.
Antioxidants paired with sunscreen help protect against oxidative and UV damage, while pigmentation-prone skin can benefit from azelaic acid combined with targeted brightening peptides.
Spend smarter on your skincare routine
The fundamentals of a good skincare routine remain consistent: cleanse, treat appropriately, hydrate, support the skin barrier and protect your 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 adds: “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.
The goal is to spend wisely on hardworking products that earn their place in your routine while leaving room in your skincare budget for in-clinic treatments that products alone cannot replicate.
