1, you must use it after lotion: Generally speaking, whitening essence is the third step in the whitening process, which is the step after cleansing and lotion. Never use it after lotion or cream. In that case, the essence of the essence can only be absorbed by lotion or cream, and its efficacy is greatly reduced.
2, the dosage does not need to be much: essence is generally a concentrated ingredient, and the dosage does not need to be much. If you use too much, it will easily cause skin allergies, which is also a waste. Generally, the size of two or three soybeans is enough. If the skin is particularly dry or old, you can add a little more.
3. Massage slightly after use: Apply whitening essence to your face, and a little massage will promote the absorption of ingredients more effectively.
4. Don't use it for a long time: Even if you really want to whiten, it's best not to use whitening essence for a long time. After long-term use, the response of cells is no longer sensitive and the effect is not obvious. It will be better to take a break before using it.
