The higher the concentration of mandelic acid, fruit acid and salicylic acid, the better? Will skin become brittle and thin if I use the wrong skin rejuvenating products?
What is the difference between mandelic acid, fruit acid and salicylic acid? The higher the concentration, the better?
“Acid” products such as fruit acid, mandelic acid, and salicylic acid are very popular. Is it suitable for everyone to use acidic skin care products for skin rejuvenation? Dr. Lan Zhengzhe, director of the dermatology department of Chung Ho Memorial Hospital of Kaohsiung Medical University, reminds that excessive use of acid products may penetrate into the deep layers of the skin and cause long-term damage to the skin.
Dr. Lan Zhengzhe explained that acids can be roughly divided into two types: “hydrophilic” and “lipophilic”. Hydrophilic ingredients, such as fruit acids, have smaller molecular weights, better penetration, and a stronger tingling sensation when applied to the face. Lipophilic products such as mandelic acid and salicylic acid can generally penetrate the shallow layers of the skin and have relatively low irritation.
Dr. Lan Zhengzhe said that regardless of the acid concentration, it may penetrate the skin as long as it is wiped. Therefore, acidic ingredients are usually used for inter-office treatments and are not recommended for regular daily maintenance. If your skin metabolism is good but you overuse skin peeling products, your skin may become inflamed or fragile.
What should I pay attention to before and after skin rejuvenation? Be sure to wear sunscreen when your stratum corneum becomes thinner
Which groups of people use acids? Dr. Lan Zhengzhe pointed out that if young people have severe acne and dark spots, they can be improved clinically with acid treatment. Especially for acids with higher concentrations, it is recommended to be evaluated by a dermatologist before use.
Dr. Lan Zhengzhe said that acids with low concentrations generally have a relatively limited “skin rejuvenation” effect. If your skin is healthy, just pay attention to cleansing, moisturizing, and proper sun protection. If the skin problem is prone to flaking or dullness, it will be recommended to moisturize the skin first. Once the skin appears red, swollen, inflamed and other symptoms, you should receive professional dermatological treatment instead of intensive maintenance.
Dr. Lan Zhengzhe reminds that usually after acid treatment, the skin will become fragile and lose a lot of water, so be sure to moisturize and protect yourself from the sun. In particular, the “cuticle” after skin rejuvenation will become thinner, and the function of isolating ultraviolet rays will be weakened. If it is directly exposed to sunlight, it is easy for ultraviolet rays to damage the deeper layers of the skin.
Excessive use of acids will weaken the skin’s “barrier” function, making it easier for external forces to penetrate deeper into the skin, making the skin prone to inflammation, sensitivity and irritation. After the skin surface is weakened, it takes a long time to recover.
Hormones and biological clock affect skin condition. Eat antioxidant foods to prevent free radicals.
Skin conditions caused by working shifts or staying up late are a problem for many people. Dr. Lan Zhengzhe said that skin conditions are indeed related to factors such as biological clocks and hormones. The treatment will be tailored to the patient’s symptoms, such as acne and dull skin. The correct way to deal with skin problems is through immediate and correct use of medication and improvement of eating habits.
If your skin is in poor condition for a long time, you should still pay attention to a balanced diet and adequate hydration. Dr. Lan Zhengzhe said that daily intake of foods with antioxidant properties, such as broccoli, spinach, carrots, kiwis, red peppers, etc., can help reduce free radical damage to the body and is also beneficial to skin health.
