1. Adjust according to the skin condition and needs: decide whether to replace the essence according to the current skin condition and needs of individuals. If the currently used essence cannot meet the needs of the skin (such as skin changes during the season change, specific skin problems, etc.), it is recommended to replace it with a more suitable essence product.
2. Insist on using to observe the effect: After selecting a essence and starting to use it, it is recommended to use it for at least a period of time (such as one month) to fully observe its effect. Skin improvement is a gradual process, and frequent product changes may not be conducive to evaluating the effectiveness.
3. Avoid excessive stimulation: If the skin is particularly sensitive to certain essence or has adverse reactions (such as redness, swelling, itching, etc.), it should be stopped immediately and replaced. At the same time, it is not recommended to change the essence of different brands or efficacy frequently to avoid unnecessary burden and irritation to the skin. When replacing, gentle and non irritating products should also be selected, and attention should be paid to observing skin reactions.
