Using emulsion paint on canvas is not ideal for several reasons, primarily related to its composition and intended application. Emulsion paints, typically used for interior and exterior wall painting, are water-based and consist of tiny droplets of oil suspended in water. This makes them perfect for large surfaces where durability and ease of application are important. However, when considering their use on canvas for artistic purposes, several factors come into play. Firstly, emulsion paints lack the flexibility required for canvas art. Canvas can stretch and flex, especially over time, which might cause emulsion paint to crack and peel. Secondly, these paints are not formulated to adhere properly to the smooth surface of canvas, leading to poor adhesion. Thirdly, they don't offer the same color vibrancy and depth that acrylics or oils do, which are specifically designed for canvas. If you're set on using emulsion paint for a specific effect, consider priming your canvas with a suitable primer first to improve adhesion. You could also mix in some flexible additives to reduce cracking. For best results, however, it's recommended to use artist-grade materials like acrylic or oil paints, which are specifically designed for canvas and offer better performance in terms of adhesion, flexibility, and longevity.

Polymerases, critical enzymes in the process of DNA replication and RNA transcription, attach to the 3’ end of the nucleotide chain. They catalyze the sequential addition of nucleotide triphosphates (dNTPs for DNA polymerases or NTPs for RNA polymerases) to the growing chain by forming a phosphodiester bond between the 3’ hydroxyl group of the last nucleotide on the strand and the 5’ phosphate group of the incoming nucleotide. This directionality (adding nucleotides to the 3’ end) is vital for the fidelity and regulation of genetic information transfer. The requirement for a primer with a free 3’-OH group on which to initiate synthesis reflects the enzyme's inherent specificity and ensures accurate DNA replication and RNA transcription.

To use COSRX BHA Skin Returning Emulsion effectively, start by cleansing your face thoroughly. After cleansing, apply a toner to balance your skin's pH. Take a reasonable amount of the emulsion and gently spread it over your face and neck, focusing on areas prone to breakouts or excessive oiliness. Use your fingertips to tap the product into your skin lightly, ensuring better absorption. It’s best used in your nighttime routine because BHAs can make your skin more sensitive to sunlight. However, if you apply it during the day, follow up with a broad-spectrum sunscreen to protect your skin. Given its BHA content, introduce it gradually into your regimen to see how your skin reacts, starting with 2-3 times a week and adjusting as necessary. The COSRX BHA Skin Returning Emulsion is designed to exfoliate, prevent blemishes, and maintain your skin's moisture balance.
