- Evening routine (most common approach):
- Evening: Peptide serum + Retinol + Moisturizer
- Why: Retinol degrades with sun exposure; evening maximizes effectiveness
- Peptides can amplify retinol's overnight repair
- Separate AM/PM (alternative approach):
- Morning: Peptide serum + Vitamin C + SPF
- Evening: Retinol + Moisturizer
- Why: Spreads actives across day; reduces evening product layering
- Which is better: Personal preference. Both work. Evening application together is more convenient; separate timing may reduce any theoretical interference.
