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. The creams with a concentration above 15% may need to be kept only for a few minutes and then wiped off.
For many people, using glycolic acid 2-3 times a week is sufficient to achieve benefits without significant side effects. If you want to use it daily, consider starting with a lower concentration and gradually increasing usage as your skin builds tolerance.
Concentrations between 5-10% of glycolic acid are considered most effective for exfoliation on a regular basis. There are also more intense, rinse-off glycolic acid peels featuring higher concentrations of AHAs, which you can use at home on an occasional basis, about once a week, to improve the look of deeper wrinkles.
Glycolic acid can remove the very top layer of skin cells without the need for scrubbing, which can cause irritation. It is also useful in treatments for acne, hyperpigmentation, and the visible signs of aging.
The ideal percentage of glycolic acid for at-home use would be 8% to 25% percent, with 25% being what I call the “high normal.” With higher concentrations, formulations matter! It is important to note that home use AHA creams, lotions and serums are buffered, compared to AHA peels with lower pH.
Glycolic Acid, especially in high-strength solutions, can irritate the skin. If you have sensitive skin, a low-strength glycolic acid treatment can be added to your skincare routine. However, you should introduce them gradually, utilizing them just once or twice a week.
“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.
To clear blackheads, glycolic acid can take 3-4 weeks to take effect for clearer, congestion-free skin. This is because it takes time and repeated use for glycolic acid to break down pore-blocking dead skin cells and debris for clearer skin that doesn't have any congestion.
To achieve smoother, healthier, and more radiant skin, start by removing your makeup and then cleanse your face. Also, ensure your skin is properly dried: applying on wet skin will be less effective and less well-tolerated, as the presence of water makes the acid more irritating.
By penetrating the pore, chemical exfoliants such as glycolic acid are able to smooth texture and clear up any ingrown hairs or razor burn on your underarms. It's also a useful way to unclog congested sweat glands that can come from using antiperspirant deodorants.
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.
Dr Zamani says: “Overusing glycolic acid can leave the skin red, dry and more sensitive to the sun. This can cause premature ageing, thinning of the skin and heightened risk of pigmentation.”
Glycolic acid can be used on the face and let it absorbed into the skin by leaving it on all night. Rinse off with water the next day.
For at-home products, glycolic acid is safe for topical use in concentrations of up to 10%, and up to 70% for in-clinic services performed by a dermatologist or health care professional.
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.
Signs that glycolic acid is working include smoother skin texture, fewer breakouts, and a more even skin tone. Some people may also notice a light tingling sensation on application, which is normal.
Common side effects of Glycolic Acid include dry skin, erythema (skin redness), burning sensation, itching, skin irritation, and skin rash. Glycolic Acid can make the skin more sensitive in the sunlight, hence always use sunscreen and protective clothing before you step outdoors.
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.
It Can Reduce Breakage
Many people experience hair breakage, making it difficult to grow the hair thick and long. Glycolic acid can nourish and hydrate the hair, which, in turn, prevents tangling, making it easier to style the hair without it breaking off.
It is important to identify the appropriate concentration of glycolic acid for your specific skin concerns. Lower concentrations, typically under 4%-5% like the Facial Enhancement Cream, provide gentle exfoliation and may be used once or twice daily.
Glycolic acid is highly effective in reducing dark spots and treating hyperpigmentation. It works by promoting the shedding of pigmented cells and encouraging the growth of new, evenly pigmented skin cells. This process helps to lighten dark spots and improve the uniformity of the skin's tone.
In conclusion, a glycolic acid concentration of 7% to 17% is generally considered effective and safe for improving skin texture and reducing the appearance of fine lines and wrinkles.
Reality: Glycolic acid can help to reduce the appearance of fine lines and wrinkles, but you may need a stronger concentration of glycolic such as the Ultra Anti-Aging Cream to be effective for deep wrinkles. Myth 4: Glycolic acid can cause sun sensitivity.
Hyaluronic Acid is one of the best hydrating ingredients, as it can hold up to 1,000 times its own mass in hydration. Therefore, if you're using Glycolic Acid, we highly recommend following up with a Hyaluronic Acid treatment. This will help undo the drying side effects and restore balance within the skin.
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.
