Physiologically, a woman's skin begins to decline gradually after the age of 25. At your present age, you can properly do skin care 2-3 times a month, depending on your current skin condition, whether to whiten or moisturize. Remember to choose a beauty salon with perfect formal procedures. Secondly, the choice of beauty products is as important as the beauty skills of beauticians. The product is not suitable for your skin. If the technique is too light and ineffective, it will be counterproductive if it is too heavy. Beauty salons generally do not recruit beauticians with bad skin, which will affect their reputation. I suggest you choose a set of skin care products suitable for your skin, with high cost performance and good reputation, and persist in beauty and skin care.
