Frequently asked questions

What's the difference between retinol and retinal?
Both are retinoids; retinal (retinaldehyde) converts to active form faster, so it can work quicker — but may also feel stronger. Start low and slow with either.
How do you start using retinol?
Begin 1–2 nights a week, apply a pea-sized amount to dry skin, moisturize well, and always wear sunscreen the next day. Build up as tolerated.
