Retinol

Everything about Retinol Korean Skincare

Retinol , also known as vitamin A, is one of the most representative fat-soluble vitamins and has long been used in skin care. This time, we want to give people a simple introduction to retinol, which we've heard a lot about but still find difficult to understand.

How retinol works

Improvement of wrinkles and skin elasticity

Prolonged exposure to ultraviolet rays can lead to a decrease in collagen, elastin, and hyaluronic acid, which are essential elements that form the skin. Retinol can plump up skin that becomes hollow and improve elasticity and wrinkles by promoting the synthesis of these depleted components in the skin.

Improving skin texture by exfoliating.

Premature aging slows the rate of new keratin cell formation, which also slows the shedding of dead keratin cells by increasing the skin's turnover time. Retinol can remove dead skin cells and improve skin texture by promoting the formation of new keratin cells and normalizing the turnover time.

Improvement of imperfections

Increased sebum production in the pore leads to skin problems such as acne, and retinol can not only improve skin problems but also improve hyperpigmentation caused by skin problems by reducing sebum to suppress sebum cell proliferation.

Skin reactions and caution for use

Retinol use can cause skin reactions that are not easily observed with other ingredients. Depending on skin type, skin reactions such as stinging, burning, peeling, and redness may occur. These skin reactions are symptoms that can occur when retinol is working effectively on the skin. This is not a common phenomenon for all skin types and may disappear after a sufficient adjustment period. It is recommended to pay extra attention to the condition of your skin while using retinol. However, in the case of pregnant and lactating women, it can cause adverse effects on the fetus, so avoid using it during this period.

Tips for Adjusting to Retinol

It's important to use a product with a high concentration of retinol and to go through a guided adaptation process. During the adaptation period, you may experience temporary skin reactions such as tingling, redness, flaking, etc., or no reaction may occur. Even if there's no reaction during initial use, it's recommended to use it according to the instructions initially, as you may experience an adaptation reaction later. If the reaction to retinol persists after the adaptation period, it's best to gradually increase the amount and cycle of use, taking your skin's condition into account, rather than increasing it all at once. If your skin is prone to reactions, it may be helpful to first use "The 6 Peptide Skin Booster Serum" or "The Hyaluronic 3 Serum" before using COSRX retinol.

Retinol is an unstable ingredient to ultraviolet rays, therefore it is recommended to use it at night and wear sunscreen during the day while using it.
