Now, the important thing to remember is, glycolic acid comes in various concentrations. It is OK to use 1-2% containing glycolic acid face wash or ointments daily. The creams have a higher glycolic acid content (10% and above) and must only be used once or twice a week to avoid skin irritation.
You don't necessarily have to skip glycolic acid just because you tend to get dark spots, but to be safe and minimize irritation, you should stick with low concentrations (think 5 to 10%), according to Dr. Ciraldo. And again, using it just one or two times a week can also keep skin calmer, Dr. Marcus adds.
Dosing. Glycolic acid has most often been applied to the skin by adults in lotions and creams containing glycolic acid 10% to 15% once or twice daily for up to 4 months.
'Repeated use might end up damaging the collagen -- the deeper layers of skin -- giving rise to thickening, paleness and shininess (imagine Hollywood actors who've had too much facial work done). '
Using glycolic acid can benefit the skin, but overdoing it can lead to unwanted consequences. Excessive use can cause irritation, redness, itching, and burning sensations, leaving your skin feeling dry and sensitive.
Superficial peels, such as glycolic acid or lactic acid peels, typically provide results that last for several weeks to a few months.
Can I use glycolic acid everyday? Short answer: yes, Glycolic Acid can benefit your skin, but the key is finding the right strength that your skin can tolerate. As dermatologist Dr. Bottiglione explains, irritation or redness may occur initially, but there is no need to worry as permanent scars are uncommon.
Glycolic acid can cause irritation and redness if you have sensitive skin or overuse the product. Since glycolic acid can make your skin sensitive to the sun, remember to wear sunscreen and consider using glycolic acid at night.
Be patient with the process: Your skin may feel a bit rough after your first few treatments. This is normal and just means that the glycolic acid is working. Unless your skin is irritated, keep using your glycolic acid product. You should slowly start to see smoother, more healthy skin.
Underarm deodorants work by either inhibiting the growth of these bacteria, or by halting perspiration altogether. Acids such as glycolic and salicylic work as effective natural deodorants. Their low pH makes it impossible for odor-causing bacteria to survive on your skin, leaving you feeling fresh and confident.
Skin purging is said to last 4-6 weeks, however, everyone's skin is different (2). This is only temporary and will eventually subside as your skin adjusts to the new treatment. In the meantime, it is important to cleanse gently and avoid picking at your skin, as this can cause further irritation.
6. Always moisturize after use. Glycolic acid exfoliates and hydrates the skin, but it can irritate or dry out sensitive skin. Always follow your glycolic acid application with an additional light moisturizer to reduce the effects of dryness and irritation on the skin.
Glycolic acid is easy to use because there are so many ways to incorporate it into your skin care routine. As a rule of thumb, use one glycolic acid product at a time to avoid irritation, and incorporate it into your evening routine, since it makes skin more sensitive to sunlight.
“Those with darker skin tones, need to be cautious with glycolic acid,” warns Dr Buldeo. “It can cause a paradoxical darkening of the skin by stimulating melanocytes,” These are the melanin-producing cells in your skin's deepest layer so this can lead to hyperpigmentation in black skin.
What NOT to mix with Glycolic Acid. Retinol, other AHAs/BHAs, Vitamin C: Using these ingredients alongside Glycolic Acid in the same routine could irritate the skin. However, alternating them between your morning and evening skincare routine means that you can enjoy the benefits without the risk of damaging your skin.
Clinically speaking, retinol lacks the penetrative strength of Retin-A and glycolic acid, as it remains inactive and fails to reach beyond the superficial layer of the skin. Conversely, glycolic acid has the ability to deeply penetrate the skin, breaking down the "glue" that holds together dead and dull skin cells.
One to two months, dark uneven skin tone leaves. One to six months, new collagen and elastin removes wrinkles, skin is firm, and you're looking younger! Small scar reduction, some acne scars are barely noticeable.
Neutralisation is required to terminate the action of gly- colic acid peels and can be achieved using water, sodium bicarbonate, sodium hydroxide or ammonium salt solu- tions.
(1) Because glycolic acid has no end point, allowing the acid to travel deeper than intended if left on the skin too long, it requires neutralization to end the peeling process. Due to its small molecular size, glycolic acid also has the ability to absorb quickly and can cause the skin to peel unevenly.
Glycolic acid and niacinamide.
Indeed, niacinamide used with AHA's like glycolic acid and lactic acid has no effect and can even cause redness. Since niacinamide has a pH of about 5-7, it can actually increase the lower pH of glycolic acid, which is about 3-4, and negate its properties.
Glycolic acid side effects
Common side effects reported after the use of glycolic acid peels include reddening; a stinging sensation or sensation of pulling of facial skin; mild burning; and temporary post-inflammatory dark spots.
Using glycolic acid and vitamin C together can have a massive, positive effect on your skin — if done in the right way. Applying your glycolic acid product first to clear the skin, followed by your vitamin C product, means that both products can be as effective as possible.
Everyday usage is acceptable while using a rinse-off product, like a cleanser with glycolic acid. But, while using a leave-on glycolic acid product (such as a serum, gel, cream, mask, or peel), one should only apply it one to three times per week.
To double down on anti-aging benefits, pair glycolic acid with either lactic acid or malic acid, both of which unblock pores so that exfoliation is more effective.
As such, when using skincare products such as glycolic acid, it is advisable to maintain a suitable sun-protection routine, such as applying a broad-spectrum sunscreen. A person will also need to avoid tanning beds.
