Before recommending any home care product, Dr Rachna Sharma believes you deserve to truly understand what's in it, the science behind it, and whether it's genuinely right for your skin right now.
There's no pressure, no sales consultation. Just honest, expert guidance from a medically qualified practitioner who will tell you the truth about what your skin actually needs.
"The products I recommend for home are an extension of the treatment plan I build with you in clinic, not an upsell. If it won't genuinely help your skin, I won't recommend it."
Dr Rachna Sharma, Cosmetier
Toskani Med is a bioregenerative aesthetic medicine brand dedicated to advanced skin regeneration technology, with polynucleotides at the core of their innovation. LUMICEN Boost Serum was developed to bring the benefits of polynucleotide (PDRN) Complex, long used in medical-aesthetic treatments, into an intensive formula for home use.
We love and trust LUMICEN Boost Serum here at Cosmetier because it’s a genuine polynucleotide treatment you can use on its own at home, or alongside your in-clinic treatments.
In a clinical study of 30 volunteers over 15 days, 95% felt their skin was visibly regenerated and repaired, with measurable improvements in hydration, elasticity and firmness, results directly attributed to the polynucleotide complex at the heart of the formula.
At the heart of LUMICEN Boost Serum is polynucleotide (PDRN) Complex at 3% concentration, the maximum available in a home care serum, combining low and medium molecular weight polynucleotides to maximise results. This is paired with Hyaluronic Acid 4D, four types of hyaluronic acid working together to hydrate every layer of the skin and support its natural elasticity alongside the polynucleotide complex.
In clinical testing*, volunteers using this polynucleotide serum for 15 days saw improvements of up to 29% in firmness, 75% in elasticity and 77% in hydration, alongside visible reductions in erythema and improved skin texture, all attributed to the regenerative action of the polynucleotides.
