Crepey skin, dullness and loss of firmness: evidence-supported treatment options for improving skin quality

Thursday, 09 July 2026 by Dr Alek Nikolic

Crepey skin, dullness and loss of firmness result from declining collagen, elastin and hyaluronic acid in the dermis. Evidence-supported treatments include skin boosters for deep hydration, microneedling with Dermapen 4 to stimulate collagen remodelling, and bio-remodelling injectables. A careful skin assessment guides which combination is appropriate for your skin.

Polynucleotide injections: what the current evidence actually shows and the questions to ask before trying a trending treatment

Polynucleotide injections are injectable treatments derived from purified DNA fragments that work by stimulating tissue repair and supporting the skin's natural regenerative processes. Clinical evidence suggests improvements in skin quality, hydration, and elasticity, though research is still maturing. Suitability depends on individual skin assessment rather than trend alone.

Regenerative Aesthetics Explained: Which Collagen-Stimulating Treatments Are Evidence-Based and Which Are Still Unproven

Thursday, 09 July 2026 by Dr Alek Nikolic

Regenerative aesthetics refers to treatments that stimulate the skin's own collagen and elastin production rather than simply filling or relaxing tissue. Evidence-based options include polynucleotides, hyaluronic acid skin boosters, calcium hydroxylapatite biostimulators, and medical-grade microneedling. Several newer modalities, including certain exosome therapies and growth factor serums, currently lack sufficient clinical data to support routine use.
