- you would rather it just work, without depending on the product being at the right pH
Choose Vitamin C (LAA) if
- dark spots, dullness or an uneven tone are what you want to work on
- your skin is sensitive or reacts easily
- you are pregnant, since Retinol should be avoided and Vitamin C (LAA) is at least one to raise with your doctor
The honest bottom line: Both earn their place. Vitamin C (LAA) is the kinder pick if your skin reacts easily, otherwise it comes down to preference.
Pregnancy: Retinol should be avoided in pregnancy, and Vitamin C (LAA) is one to check with your doctor first.
Can you use them together?
Use with careUse these with care.
Pure vitamin C and retinoids prefer different pH levels, so layered together they can be a little less effective and more irritating. Vitamin C in the morning is a convention, not a measured rule; the retinoid in the evening is what the labels say.
Do this: Keep vitamin C for mornings and the retinoid for evenings.

How to introduce Retinol and Vitamin C (LAA)
- Patch test each one first: a coin-sized amount on your inner forearm for two or three days, watching for redness or stinging.
- Split them across the day: Vitamin C (LAA) in the morning, Retinol at night, rather than layered in the same routine.
- Start the retinoid at once or twice a week and increase gradually, giving your skin time to settle between steps.
- If skin turns tight, flaky, red or starts to sting, drop back a step and let your barrier recover for a few days before pushing on again.
There is room for both here, as long as you build up gently and let your skin set the pace.
For your skin type If your skin is sensitive or reactive, take this pair slowly: Retinol is the higher-irritation ingredient here, and using actives close together magnifies that.
