CPB is a bit of a no-brainer when it comes to the essence. Whether it is the brightening essence that focuses on whitening and lightening spots, or the grenade essence that claims to be the skin serum, it is not very outstanding in terms of efficacy, but fortunately, it is very comfortable to use, and it is suitable for users who have a loose budget and pursue skin feel.
 
In terms of whitening formula, the Brightening Intensive Brightening Serum follows the classic formula of Shiseido's group, tranexamic acid, with 4MSK, both of which are commonly used whitening ingredients. As a protease inhibitor, tranexamic acid has a certain inhibitory effect on melanin enhancing factor groups, which is conducive to controlling the enlargement of dark spots. 4MSK, on the other hand, has shown a defensive effect against blackness deposition in vitro tests and is often used to improve pigmentation. In addition, the serum is supplemented with two whitening agents, 3-O-ethyl ascorbic acid and olea europaea leaf extract. Compared to niacinamide, this set of whitening ingredients in the translucent serum is milder, if you are not uncomfortable with niacinamide, you can try this serum. However, due to factors such as content, the effect of the brightening essence in lightening pigmentation and acne scars is not very significant, and the effect cycle is long.
 
In terms of user experience, the Luminous Serum is very comfortable. The addition of a variety of moisturizers and a high content of alcohol make the essence moisturizing and maintaining a refreshing skin feel. In addition to alcohol, the serum contains acids and antibacterial and anti-inflammatory agents, which is quite suitable for acne skin, but it is irritating and not recommended for users with sensitive skin. The essence is a white emulsion, light in texture, easy to spread, and has a subtle rose scent. With the silica in the formula, the essence appears matte after being applied to the face, smooth and non-sticky, suitable for oily skin.
 
If you don't have dark spots and acne scars and are looking for a comprehensive skincare product, you may want to try the essence of the skin, also known as the grenade serum. In the formula, more than 10 kinds of moisturizers such as butylene glycol and glycerin are the mainstay, and anti-inflammatory ingredients such as allantoin and hydrolyzed shellfish hard protein are used to achieve a soothing effect. In addition, deformed ethanol, citric acid and other substances can help remove old keratin and promote the absorption of subsequent products to a certain extent. The grenade essence also feels good on the skin, with a transparent watery texture with high fluidity, dry and light, and will not rub mud when layered with other skin care products. If the skin is in good condition, it only needs to moisturize and soothe and use it directly as a serum. If you are faced with problems such as dryness and wrinkles, you can also superimpose more targeted products. The price of the grenade essence is 2180 yuan for 40 ml, which is in the ranks of expensive essences, and the skin care effect is relatively basic and the cost performance is slightly lower.
