The alternating use of fruit acid and retinol

is good for skin care. Those who know the nature of the skin and understand the effects of various products can apply the technique properly. Fruit acid (Glycolic Acid) and retinol (Retinol) are both good agents for skin care, but their properties are special, so they need to be used alternately.

Fruit acid is derived from natural fruits and vegetables, with warm and rejuvenating properties. It can loosen the connection between keratinocytes, make old waste keratin shed, and the skin can be reborn, showing a delicate and smooth state. And it can promote skin metabolism, brighten skin tone, reduce pigmentation, and make the skin radiant.

Retinol is a derivative of vitamin A, which is effective in skin anti-aging. It can stimulate collagen production, enhance skin elasticity, reduce wrinkle formation, and tighten skin contours. It also helps to regulate keratin metabolism and improve pores.

However, both are irritating. If used in combination, the skin may be intolerant, causing redness, swelling, tingling, and desquamation. Therefore, it is appropriate to use them alternately.

When using for the first time, you can start with fruit acid. Choose low-concentration fruit acid products, such as 2% - 5% concentration, 1-2 times a week. After cleansing at night, apply evenly to the face to avoid the skin around the eyes. After the skin adapts, there is no adverse reaction, and it can be gradually increased to 3-4 times a week.

Use fruit acid at intervals of 2-3 days, and you can change to retinol. Start with low-concentration products, such as 0.1% - 0.3% concentration, and use at night. Apply a small amount to the face first, observe for 3-5 days. If the skin tolerates it, then apply evenly. After adaptation, you can gradually increase the concentration or frequency of use.

During alternate use, you need to take care of the skin. Sunscreen must be used during the day. Both causal acids and retinol can make the skin more sensitive to ultraviolet rays. If not properly protected, it is easy to cause pigmentation. And the skin should be kept hydrated, and moisturizing products should be used in a timely manner to relieve possible dryness.

In general, the use of fruit acid and retinol alternately, such as tuning and playing the piano, grasping the proportions, can play the music of skin rejuvenation and achieve the best skin care.
