French drugstores are blooming everywhere, and La Roche-Posay also uses "cosmeceutical" as its signboard, which is not actually medicinal, but pays attention to the simplicity of the formula, advocating mildness and non-allergization. La Roche-Posay's soothing conditioning mist is made from thermal water, which is simple and non-allergenic, but it also lacks obvious skin care benefits. La Roche-Posay water has a higher bicarbonate ion content than Avène spray, which is more comfortable and smooth on the face, but the spray droplets are relatively large and not as delicate as Avène.

The soothing conditioning spray is often referred to as the white spray, a pure hot spring water formula that is refreshing and cool on the face, and can instantly cool the face in summer. However, if it is left to dry freely, it will feel tight and dry, which is also a common problem of hot spring water spray. The Gentle Astringent Spray comes in a blue package and is often referred to as the Blue Spray. Blue spray has made another change to pure hot spring water spray, adding salt and zinc sulfate on the basis of white spray, which is different from moisturizing, and proposes the concept of oil control and convergence. In the early days, zinc sulfate was often used as an astringent in cosmetics, but there was no astringent effect. Therefore, there is not much difference between the two in terms of efficacy, but the texture of the blue spray is relatively less refreshing than the white spray.

La Roche-Posay began as a medical laboratory for dermatology, and later developed daily care products. In 1989, La Roche-Posay was integrated into L'Oréal, which is stronger than Avène in accordance with European pharmaceutical GMP standards. La Roche-Posay's spray specification is the same as Avène's 50/150/300ml design, the price of the soothing conditioning spray is 25-135 yuan, which is more cost-effective, and the price of the mild astringent spray is about 38-200 yuan.
