Amino acids and retinol can be used together to create a powerful skin care regimen. Amino acids are the building blocks of proteins, and they can help to improve skin hydration, reduce wrinkles, and promote healthy skin cell turnover. Retinol is a form of Vitamin A that is highly effective for reducing the appearance of wrinkles, acne, and other skin imperfections. When used together, these two ingredients can help to improve the overall health and appearance of the skin.

What can you not mix with retinol?

It is generally not recommended to mix retinol with other active ingredients such as alpha hydroxy acids, benzoyl peroxide, and salicylic acid as this can lead to irritation and dryness. These ingredients can also make retinol less effective. It is also not recommended to mix retinol with vitamin C, as the combination can cause skin sensitivity.

Can I use amino acids with tretinoin?

Yes, you can use amino acids with tretinoin, however, certain combinations may cause irritation. It is recommended to use an oil-free cleanser, such as Cetaphil or Cerave, when using tretinoin. Additionally, it is best to use a separate moisturizer and sunscreen, rather than a combination product. Amino acids can be beneficial in helping to reduce the appearance of wrinkles, but they should be used with caution when combined with tretinoin.
