PHDP5 (Intranasal Spray)
Proprietary topical peptide complex (skin-renewal spray) · Intranasal spray
PHDP5 is presented as a peptide complex in a spray format positioned around skin-cell renewal and antioxidant-oriented signalling. Peer-reviewed human evidence supporting a cosmetic or dermatological benefit is very limited, and its mechanisms in skin remain largely uncharacterised. Any renewal, hydration or wrinkle endpoints should be regarded as unproven.
Studied use areas
- Skin renewal and cell-turnover signalling (studied concept)
- Antioxidant and oxidative-stress-defence endpoints
- Hydration and barrier-comfort endpoints
- Fine-line and texture endpoints (investigational)
Safety & status
- Very limited published safety data; not an approved dermatological treatment
- Spray application — avoid contact with eyes and mucous membranes unless directed
- Requires physician assessment before use
⚕ Clinical note: This is educational information only and not medical advice. PHDP5 is investigational for skin use with very limited evidence; any use must be assessed and supervised by a treating physician, who determines suitability on an individual basis.
