YOUTHFUL Quattro Peptide Face & Eye Serum vs SkinMedica Retinol Complex 0.5

Buy the YOUTHFUL Quattro Peptide if you want a gentle peptide serum you can use twice a day on face, eyes, neck and décolleté, including if your skin is sensitive or retinol has irritated you before. Buy the SkinMedica Retinol Complex if you already tolerate retinoids and want a stronger collagen and cell-turnover treatment for texture and coarse wrinkles. The YOUTHFUL is the easier daily product and covers more areas; the SkinMedica does more for texture but needs a slow start, twice-weekly use and daily SPF.

• Choose the YOUTHFUL Quattro Peptide if you want a hydrating peptide serum for face and eyes that suits sensitive skin and can be used morning and night.
• Choose the SkinMedica Retinol Complex if your skin is already used to retinol and you want a stronger treatment for texture, tone and coarse wrinkles.
