Is this serum good for sensitive skin?

It is formulated for sensitive skin and avoids the stronger acids and retinoids that often cause irritation. Niacinamide can still sting some very reactive skin, so patch test first and start every other day.

Can I use it with retinol?

Yes. Apply this hydrating serum first, then retinol, to buffer dryness. If your skin is new to retinol, alternate nights rather than layering both every day.

How does it compare with a plain hyaluronic acid serum?

It adds niacinamide for tone and barrier support, so it does more than pure hyaluronic acid. It still will not match a retinol or peptide serum for firmness.

When should I apply it?

Morning and evening on clean, slightly damp skin, before moisturizer. In the morning, follow with sunscreen.

What is in the bottle?

One 1 fl oz bottle of serum. No applicator or extra products are included.

Is it enough on its own for anti-aging?

No. It hydrates and supports the barrier, which softens the look of lines, but pair it with sunscreen and a proven active such as retinol for real anti-aging.
