On the appropriate proportion of glycolic acid to be used
For ordinary people to use glycolic acid, the appropriate proportion must be reviewed. If the proportion is improper, it may damage the skin or fail to obtain its effect.

For beginners, the skin is delicate and intolerant to irritation, and a low proportion should be selected. The ratio of glycolic acid is about 2% - 5%, which is relatively stable. This ratio is mild, which can gradually activate the metabolic work of the skin, rejuvenate its luster, and cause less discomfort. Like a spring breeze, it brushes the skin gently and moisturizes slowly.

If the skin has already adapted and wants better results, it can gradually increase its ratio. However, it should not be rushed, and it should be increased to between 8% - 12%. At this time, the effect of glycolic acid is slightly stronger, which can further renew the keratin of the skin, remove light spots, and make the skin smooth and delicate, like a carved jade tool, more radiant.

However, the skin conditions are different, and those who have sensitive and weak qualities should not rashly use a high ratio over time. Always keep a low ratio to protect the skin. When using it, you must check the skin's response. If there is redness, swelling, or tingling, stop using it immediately and seek medical treatment.

In general, the use of glycolic acid should be based on the tolerance of the skin, step by step, and carefully select its ratio to obtain the effect of skin care without the worry of skin damage.
