- Can I use both serums on the same day?
- Yes. Use the day serum in the morning and the night serum in the evening. Do not layer retinol with the day serum's acids in one application.
- Is this set suitable for sensitive skin?
- The formulas are fragrance-free and non-comedogenic, and many sensitive-skin users tolerate them. Start the night serum twice a week and increase slowly.
- Do I need sunscreen with this set?
- Yes. Retinol makes skin more sun-sensitive, so use a broad-spectrum sunscreen every morning.
- How does it compare with a single anti-aging serum?
- It covers more ground: hydration and barrier support by day, retinol and exfoliation by night. A single serum is simpler but usually targets fewer concerns.
- Can I use it with other acids or vitamin C?
- Be cautious. The night serum already contains salicylic acid, so adding strong acids or daily vitamin C raises irritation risk. Introduce one product at a time.
- What is in the box?
- One day serum and one night serum in bottles. No cleanser or moisturizer is included.
- Where is the La Roche-Posay Anti-Aging Serum Set cheapest?
- At La Roche Posay, for $129.97, as of our latest check.
