Sodium DNA is combined with hyaluronic acid, soluble proteoglycan and mannitol to support hydration, skin conditioning and a smoother, more supple-looking complexion.

For clients looking beyond a temporary glow

COS PN is designed for treatment plans that focus on the appearance of skin quality over a personalised course of care. Texture, fine lines and reduced suppleness are considered together, alongside hydration and barrier condition.

With polynucleotides at the centre of the formula, PN gives practitioners a focused option for clients seeking a smoother, more supple-looking complexion.

Polynucleotides at the centre

Sodium DNA defines COS PN’s position within the collection and its focus on skin conditioning and visible skin quality.

Complementary hydration

Hyaluronic acid and soluble proteoglycan support moisture, suppleness and a smoother skin feel.

A considered supporting base

Mannitol and the phosphate buffer system contribute antioxidant and stabilising functions within the formula.

Choose PN for texture and skin quality

Consider PN when fine lines, reduced elasticity and uneven-looking texture are the main priorities, including texture left after fully healed blemishes.

PN or RE?

PN centres on a polynucleotide formula for skin renewal and quality. RE adds copper peptide, niacinamide and adenosine within a broader restorative formula focused on fine lines, firmness and resilience.

PN or ECM?

PN suits a general focus on skin quality and early ageing concerns. ECM is the more specifically firmness-focused option when visible laxity and crepey-looking texture dominate.

Choose by the client’s main skin goals. Each COS ampoule has a distinct focus within a personalised professional treatment plan.

COS CR | Radiance

Hydration, glow and vitality. Choose when dehydration and a dull, tired-looking complexion are the main priorities.

COS EXO | Regenerating

Calming support and comfort. Consider for stable, suitable skin where visible redness and sensitivity history influence the treatment plan.

COS PN | Repairing

Skin renewal and quality. Consider when fine lines, uneven-looking texture and reduced elasticity are the main concerns.

COS BR | Brightening

Visible pigmentation and uneven tone. Choose when dark spots and a more even-looking complexion are the priority.

COS ECM | Structural

Visible firmness and suppleness. Consider when loss of elasticity and crepey-looking texture dominate.

COS RE | Restorative

Copper-peptide-led restorative care. Consider when hydration, fine lines, loss of firmness and reduced resilience appear together.

This guide supports product selection. It does not replace a consultation, contraindication check or assessment of suitability for microneedling.

From professional treatment to a daily skincare ritual

Support a COS PN treatment plan with consistent care between appointments. Prioritise appropriate post-treatment products, then help clients establish a daily ritual that maintains hydration, barrier comfort and sun protection.
