Retinoid cream is a skincare product that contains a derivative of vitamin A, which is added to promote skin renewal, brighten skin tone, reduce acne, and boost collagen production. Here are some details about retinoid cream:

Ingredients or materials:

• Retinol is a potent form of synthetic vitamin A.
• Retinol can appear in an ingredients list as retinyl acetate, retinyl palmitate, or tretinoin.

Positive effects:

• Retinoid cream can help smooth fine lines and wrinkles, shrink pores, clear up acne, and even out skin tone.
• Retinoid cream can boost cell turnover, remove superficial dead skin, flatten the top layers of cells, and leave skin looking smoother, more luminous, and even-toned.

Negative effects:

• The more concentrated the product, the more negative side effects it may have. Prescription retinoids are more active and can irritate the skin sooner.
• Retinoid ingredients may speed the development of skin tumors and lesions on sun-exposed skin.
• Daily skin application of vitamin A creams may contribute to excessive vitamin A intake for pregnant women and other populations.

Its important to note that retinoid cream can cause skin irritation, redness, and flaking, especially when first starting to use it. It's recommended to start with a lower concentration and gradually increase over time.
