So, while BHAs (like AHAs) have benefits for all skin types—hydrating, diminishing the look of lines and wrinkles, visibly improving skin's firmness, texture, and tone—its multi-tasking, standout properties make it ideal for those with normal to oily, bumpy or congested skin that may be showing signs of aging.
AHA is also good for dry skin. It's made up of molecules that love water, and it helps improve the skin's moisture content. Beta Hydroxy Acid (BHA) is best for acne-prone skin and those with deeper skin concerns since BHA penetrates further into the skin. While AHAs love water, BHAs love oil.
Markowitz warns that AHAs and BHAs are strong humectants that have a peeling effect and can cause the skin to dry out if overused. For this reason, they should be used when you want your skin to glow a few times a week as opposed to every day.
They're both chemical exfoliants that help remove dead skin cells from the top layer of your skin. Some say AHAs and BHAs have anti-aging effects, like smoothing fine lines and improving the texture of skin.
You don't need to wait for the BHA or AHA to absorb or dry; you can apply any other product in your routine - moisturiser, serum, eye cream, or sunscreen - immediately afterwards.
"Moisturizing after applying AHA and BHA is extremely important so as to limit irritation. Look for ceramides, petrolatum, hyaluronic acid, and glycerin to hydrate and soothe skin," says Dr. Marchbein.
BHAs are thought to self-neutralize after about 20 minutes, so most skincare experts advise letting it fully dry for at least 15 minutes before continuing with your regular skincare routine (i.e. essences, serums, moisturizers, spot treatments).
"Do not overuse an alpha-hydroxy-acid product," confirms Bolder. “Once every other day is plenty, unless you are on a programme with an expert that says otherwise.” However, it is often safe to use BHA daily.
When it comes to reducing large pores, a leave-on exfoliant with Salicylic Acid (a BHA i.e. beta hydroxy acid) is your best friend.
Because BHA is oil-soluble, it exfoliates not only on the surface of skin, but also inside the pore lining. That kind of exfoliation can trigger a mass exodus of inflammatory substances and oil that, under certain conditions, can create more breakouts.
It can also be used if you suffer from Keratosis Pilaris, especially in combination with a water-soluble body wash. Sensitive skin: BHA has soothing properties that are ideal for sensitive, red skin, whatever your skin type.
If you struggle with dry skin, topical application of niacinamide has been shown to boost the hydrating ability of moisturisers so the skin's surface can better resist the moisture loss that leads to recurrent dry, tight, flaky skin.
Yes, it is safe to use niacinamide and BHA together. Both formulas are effective yet gentle and contain additional calming and restoring antioxidants. Some people with extra-sensitive skin may find that alternating them by using one in the morning and one at night works best.
Acid exfoliants, such as AHAs, can remove rough or flaky skin without causing irritation. As a result, they can reduce the appearance of dry skin, blemishes, and keratosis pilaris.
Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are chemical exfoliants that can totally transform your skin game. While AHA helps renew the skin's surface, BHA gets deeper into the pores to remove dead cells and excess sebum. Alpha hydroxy, beta hydroxy and Vitamin C are all acidic ingredients.
sun exposure, especially if you don't wear sunscreen. genes (if your parents have oily skin and large nose pores, you will likely have the same) hormone fluctuations, such as during menstruation or puberty. alcohol or caffeine consumption (these can dry out your skin and lead to increased sebum production)
It may take 5-14 days to see results (source) Don't give up! My reactive skin had zero irritations and redness. I was extremely relieved as most acne products were too strong for me. Just avoid eczema spots or any other sensitive areas on your face.
Niacinamide reduces inflammation , which may help ease redness from eczema, acne, and other inflammatory skin conditions. Minimizes pore appearance. Keeping skin smooth and moisturized may have a secondary benefit — a natural reduction in pore size over time.
You don't need to wait for your BHA or AHA to absorb or dry; you can apply any other product in your routine—moisturizer, serum, eye cream, or sunscreen—immediately afterward.
Generally speaking, dermatologists say purging should be over within four to six weeks of starting a new skin care regimen. If your purge lasts longer than six weeks, consult your dermatologist.
Can you use BHA and vitamin C together? Yes, you can, but only if you use each ingredient properly in your routine.
You'll want to use your BHA product first, not only because BHAs are lower in pH but also because they are oil soluble and AHAs are not.
Can I moisturise after salicylic acid? Absolutely, if anything I strongly suggest moisturising after using salicylic acid. Not only will this soothe and calm the skin after applying the potent BHA to your skin.
It's possible to use Niacinamide and BHA apart. First, apply BHA, wait at least 30 minutes, then Niacinamide. That should give it appropriate time so both products can work at their intended pH level. When layering skincare products, always go from lowest to highest pH.
