Theory of Vitamin C and Vitamin A

Recently, the skincare theory of using vitamin c in the morning skincare routine and vitamin a/ retinol in the evening routine. They are the most trendy skincare combination to achieve anti-ageing and youthful complexion.

Why C in the morning and A in the evening?

The evidence behind the theory is that vitamin c has powerful antioxidant properties. Hence it’s best to add to your morning skincare routine to protect and defend your skin against the free radicals, pollutants and UV rays that cause damage to your skin and result in pigmentations, fine lines, and wrinkles.

Vitamin A/ retinol is a significant ingredient to maintain a youthful complexion. It reduces fine lines and wrinkles by increasing the production of collagen. As we age, collagen production declines by 1.5% per year. Therefore, our skin will start to age, and the signs of lines and wrinkles will appear on our skin. Retinol will assist with collagen production and, to maximise the benefits of its purpose, it’s best to use it in the evening.

Who is it suitable for?

This combination is suitable for those who are seeking for bright, clear, and youthful complexion. Try this combination if you are still having trouble with skin conditions, like acne marks, pigmentations, or even skin tone, and reduce the wrinkles on your complexion.

However, if you have sensitive skin, you need to start with a gentle vitamin c and retinol. This combination causes our skin to become sensitive to sunlight, and wearing sunscreen during the day is strongly recommended to avoid flaky skin and sensitivity with our skin.


This combination of vitamin c and retinol is worth trying if you seek to correct dull skin, uneven skin tone, hyperpigmentations, and wrinkles. But be cautious if you also suffer from having sensitive skin, as it may increase skin sensitivity to daylight. You need to wear sunscreen during the day to prevent skin inflammation and reduce sensitivity to sunlight.
