AHAs and BHAs are types of hydroxy acids. You can find both acids in a variety of:
The purpose of both AHAs and BHAs is to exfoliate the skin. Depending on the concentration, a related product may remove dead skin cells from the surface of the skin, or it may remove the whole outermost layer.
Still, neither type of hydroxy acid is “better” than the other. Both are highly effective methods of deep exfoliation. The differences lie in their uses.
AHA stands for alpha hydroxy acid. BHA stands for beta hydroxy acid.
AHAs are water -soluble acids made from sugary fruits. They help peel away the surface of your skin so that new, more evenly pigmented skin cells may generate and take their place. After use, you’ll likely notice that your skin is smoother to the touch.
On the other hand, BHAs are oil-soluble. Unlike AHAs, BHAs can get deeper into the pores to remove dead skin cells and excess sebum.
Although AHAs are often marketed as safe for all skin types, you’ll want to take care if you have extremely dry and sensitive skin. You may need to gradually work up to daily use to avoid irritating your skin.
BHAs, on the other hand, are primarily used for acne and sun damage. These products go deep into your hair follicles to dry out excess oils and dead skin cells to unclog your pores. Because of these effects, BHAs are most suitable for combination to oily skin. Lower concentrations may be used to help calm sensitive skin. You may also have more success with BHAs if you wanted to reduce rosacea-related redness.
All AHAs yield significant exfoliation. Still, the effects and uses can slightly vary between types of acids. Your selected AHA should have a maximum concentration between 10 and 15 percent. Apply new products every other day until your skin gets used to them. This will also reduce the risk of side effects, such as irritation.
No matter which AHA you choose, the strong exfoliating effects make your skin more sensitive to the sun. Wear sunscreen every morning to prevent burns, age spots, and increased skin cancer risks.
Lactic acid is another common AHA. Unlike other AHAs made from fruits, lactic acid is made from lactose in milk. It’s also known for its significant exfoliation and anti-aging effects.
Tartaric is another type of AHA. It’s made from grape extracts, and may help alleviate signs of sun damage and acne.
Citric acid is made from citrus fruit extracts. Its main purpose is to neutralize the skin’s pH levels and to even out rough patches of skin. Citric acid makes a good serum or toner used before applying a moisturizer. It may even help work with sunscreen to provide maximum UV protection.
Malic acid is a type of AHA-BHA crossover. It’s made from apple acids.
Mandelic acid contains larger molecules derived from almond extracts. It can be combined with other AHAs to increase exfoliation. Used alone, the acid may improve texture and pore size.
Salicylic acid is the most common BHA. Concentrations can range between 0.5 and 5 percent, depending on the product at hand. It’s a well known as an acne treatment, but it can also help calm down general redness and inflammation.
Citric acid while primarily classified as an AHA, some formulations of citric acid are BHAs, too. Rather than even out your skin’s pH levels, this type of citric acid is primarily used to dry out excess sebum and clean out dead skin cells deep in your pores.
Don’t mix face acids
- Don’t use salicylic acid with any other acid at the same time. Extreme skin irritation may occur when mixed.
- Avoid salicylic acid with products that contain niacinamide.
- Don’t use glycolic acid or lactic acid in combination with ascorbic acid (vitamin C). This will cause the ascorbic acid’s benefit to disappear even before it begins to work.
- Avoid using AHAs with retinol.
AHAs and BHAs, if these actives are used at too high of a concentration or too frequently, they can irritate your skin and compromise the skin barrier.
Dermatologists don't — and can't — argue there. In my opinion, [retinoids'] benefits are more about the skin's appearance," says Dr. Katta. "The compounds in retinoids can help boost collagen, but they're not necessary for healthy skin. The most important factor in maintaining healthy skin is about protection and promotion." Research shows that although retinoids thicken the skin overall, they thin the skin barrier, the built-in protective layer that guards against invading pathogens and environmental aggressors and locks in moisture.
How Does Retinyl Palmitate Form Vitamin A?
The different retinoids have slightly different functions and benefits. All the retinoids are converted into retinoic acid in the body. Retinoic acid is the main ingredient that has a direct biological effect on the skin. Retinoic acid is a metabolite of vitamin A and is responsible for most of the benefits to the body and skin.
Retinoic acid is available as a prescription treatment known as tretinoin or Retin – A. Tretinoin can cause skin irritation including excessive peeling, redness, and photosensitivity which limits its use.
EWG's Skin Deep Cosmetics Database, which rates ingredients based on toxicity. Retinol can rank anywhere from six to nine out of 10, making it a "high concern" ingredient. For reference, lead and formaldehyde — two undisputed toxicants — earn 10s.
The overall product or ingredient score in Skin Deep is calculated from information drawn from the nearly 60 integrated toxicity, regulatory and study availability databases," Leiba explains. "Retinols get a high score in Skin Deep because government testing has shown that, on sun-exposed skin, these chemicals can increase the risk of skin lesions and other skin damage."
Again, there is no definitive evidence that topical retinoids lead to cancer or reproductive toxicity, but the evidence we do have is pretty much on par with that of parabens. (Read: Not agreed upon by professionals, requires more research.) So what's the difference between potentially-toxic parabens — largely shunned by both indie brands and drugstore giants as a precaution — and potentially-toxic retinoids?
The Best Alternatives to Retinol for Your Skin
Sunscreen is essential for protecting our skin from the sun’s harmful UVA and UVB rays. However, the claims made from some of these natural ingredients are proved to not be as effective as we thought.
UVA and UVB Rays
UVA and UVB are the two types of ultraviolet radiation that come from the sun. UVA rays penetrate deep into the skin, causing long-term damage such as wrinkles and age spots. UVB rays affect the surface of the skin, causing short-term damage such as sunburns. Both types of rays can lead to skin cancer.
The efficacy of natural ingredients- Zinc Oxide
Zinc oxide is one of the most common ingredients used in sunscreens. Even though zinc oxide is a chemical, sunscreens that contain zinc oxide are often referred to as natural, or physical. This means that the ingredient does not penetrate the skin but rather block the sun by sitting on top of skin.
Surprisingly, not all sunscreen ingredients protect against both UVA and UVB rays. Zinc oxide, however, does. “It’s a photostable, broad-spectrum sunscreen, so it has one of the broadest UVA coverages of all the sunscreen ingredients.
“Zinc oxide can be ‘micronized,’ meaning it’s processed into very small particles, so small that the preparation appears clear when applied on the skin.” Non-micronized formulations, she explains, are often less cosmetically elegant and are more opaque or white. So, if you’ve ever applied a sunscreen that left a white, powdery cast on your body, it most likely contained zinc oxide as a key ingredient.
Carrot seed oil
Carrot seed oil does have health benefits, but protection from the sun is not one of them. Carrot seed oil has an SPF of 38 but it does block the harmful UVA and UVB rays, and should not be used on it's own as a sunscreen.
Red raspberry seed oil
Red raspberry seed oil is a natural sunscreen with an SPF of around 28 to 50. However, it has not been proven to be effective against UVA rays. Because raspberry seed oil doesn’t offer UVA protection — which is responsible for 95 percent of UV rays — raspberry seed oil alone isn’t recommended as a sunscreen. Given its other beneficial characteristics, however, it can be used as a healing agent for other skin conditions.
Almond oil does have SPF, but it’s not very high. The SPF of almond oil is only 2 to 6. This means that you would need to apply a lot of almond oil to your skin to get the desired level of protection. Almond oil is also not water-resistant, so it’s not a good choice for activities like swimming or sweating.
Coconut oil has an SPF of around 4 to 6. The Mayo Clinic also mentions that coconut oil only blocks 20 percent of the sun’s ultraviolet rays compared to sunscreen’s 97 percent.
It’s imperative that a sunscreen provides either UV-absorbing or UV-blocking protection to be effective. There is not one scientific study proving coconut oil, or any other natural oil for that matter, provided any adequate UV-absorbing or UV-blocking protection. But as far as zinc oxide (the main ingredient for sun protection in these DIY recipes), mixing active cosmetics isn’t as simple as adding the recommended amount.
Shea butter has an SPF of around 6, also not enough protection against harmful UVA rays. However, shea butter is known for its high concentrations of fatty acids and vitamins, an ideal cosmetic ingredient for softening skin. Shea butter also has anti-inflammatory and healing properties.
There are many natural ingredients that can be effective for sunscreen. Some of the most popular include zinc oxide, titanium dioxide, and avobenzone. Each of these ingredients has its own unique set of benefits and drawbacks, so it is important to choose the one that is best suited for your needs. Zinc oxide is a physical barrier against the sun's rays, making it a good option for those with sensitive skin. It is also effective at blocking both UVA and UVB radiation. Titanium dioxide is another physical blocker that is less likely to cause irritation. It is not as effective as zinc oxide at blocking UVA radiation, but it is better at blocking UVB radiation. Avobenzone is a chemical blocker that protects against UVA and UVB radiation. However, it can be unstable in sunlight and can cause skin irritation. Ultimately, the best natural sunscreen ingredient will depend on your individual needs and preferences.

People with dry skin are aware of how difficult it is to manage such skin types. Moisturizers and other facial creams can help but relying on just that will not cut it. Flaky and rough-to- the-touch textured skin can be uncomfortable and difficult to manage, below are three things you can do to help with dry skin:
- Re-evaluate Your Routine.
Applying lotion daily is likely already part of your routine, but lotion is not the only product that matters in terms of moisture. For healthy, glowy skin, you will want to make sure that your entire regime is right for your skin type starting from the cleanser. Avoid ingredients like alcohol, or salicylic acid as it will dry out your skin. Follow with a toner and serum, they will help your moisturizer absorb into the skin. Aiona Alive offers a 4 Step Step For All Skin, suitable for dry skin to make things easier.
- Load Up On Water
Our skin is the largest organ and like all other organs, it needs water to function. Many report a healthier glow to their skin when they are fully hydrated. Though some may argue that drinking lots of water will not solve all of your dry skin problems, it can’t hurt. Besides, there are tons of other reasons for health to do so including flushing toxins from your body.
- DIY Mask
Looking to try a recipe you can make yourself? We hear a spoonful of olive oil, honey, rose water and an egg mixed together can help. Olive oil has been used as a natural moisturizer for decades by Mediterranean women who are known for having beautiful skin.
1. Protect yourself from the sun
This one sounds like a no-brainer but a shocking 90 percent of skin aging is due to the sun. Protect yourself with SPF 30 sunscreen for the face and body. Re-applying often is the key to full protection from ultraviolet (UV) radiation, which is a known human carcinogen. Don’t forget about your lips— pick up a natural lip balm with SPF if you don’t already own one.
2. Wash your face every night
Now that we are taking full advantage of the outdoors because of the warm weather, it is especially important to cleanse the day off your face. By now we know that sleeping with your makeup on is bad for your skin, but new experiments show that it can actually age the look of your skin as well. Wash the sweat, bacteria, and makeup off your face and go to bed with a clean face for fresh and healthy skin. Pro-tip: change your pillowcases often to ensure you are not resting your cheeks on built-up bacteria.
3. Drink LOTS of water
Your skin looks best when it’s fully hydrated— otherwise, skin can appear dull, and wrinkles could be more prominent. Although it is always important to load up on water, the risk of dehydration increases during the summer season. It’s best to always keep a bottle of water on hand to avoid these things that can happen to your body when dehydrated.
4. Exfoliate the dead skin away
Scrub the sunscreen and smell of adventure off your skin with an exfoliant. Once a week is enough— like with the skin on your face, you don’t want to overdo it. Top off your skin with our Elixir Mask for Body for guaranteed soft skin.
