Can retinol and niacinamide be used together? What are the benefits of using retinol and niacinamide together?

Retinol is a complete vitamin A molecule, and it and niacinamide are both skin care ingredients. The first person to propose whether retinol and niacinamide can be used together was a WeChat account celebrity. So, can these two be used together? Let's take a look.

Niacinamide and retinol can be used together to double the effect.

The combined use of "retinol" and "niacinamide" will have better effects than using them alone, but the irritation will increase and the allergy rate will rise. Before using this combination, you should first determine whether your skin can withstand it. People with sensitive and fragile skin should not join in the fun, it is really not suitable. Even for skin with strong tolerance, it is only recommended to use them in combination at certain stages, and it is not recommended to use them in this combination for a long time.

Retinol itself can also achieve the effect of whitening by improving pigmentation and accelerating skin metabolism. So in fact, retinol and niacinamide can both be regarded as "all-round tonic" ingredients that take into account both anti-aging and whitening, but they have different focuses.

The anti-aging effect of 0.25% prototype retinoic acid has always been the gold standard for anti-aging. Laboratory tests of new anti-aging products all use it as a control group, and it has not changed for many years. If you can tolerate it, retinol products are still the best anti-wrinkle choice.

Because vitamin A products have multi-faceted and multi-level effects on anti-aging, from preventing wrinkles, slowing down wrinkle formation, to improving existing wrinkles, it is effective at all three levels of anti-aging. However, retinol products have an inevitable side effect, which is that they can easily cause adverse reactions such as redness, dryness, and scaling of the skin.

P.S. So! If you can handle it, try retinol. If you can’t handle it, don’t just take it because it sounds so good. Anti-aging products such as peptides are also good.

Speaking of retinol concentration, let me add that retinol can work starting from a concentration of 0.1%. The most suitable concentration for daily continuous use is around 0.25-0.3%, which is effective without being too strong. Higher concentrations can have better effects, and 1.0% and even 1.5% are common, but the side effects are also very large. It is not suitable for long-term use and can be used as a strong care in a certain stage. In this environment, a laboratory has discovered the benefits of using niacinamide and retinol together---niacinamide can greatly reduce the side effects of retinol on the skin, which is equivalent to giving the skin a shot of "tranquilizer" after using retinol. (It seems that the soothing effect of niacinamide is not only for retinol, but also for irritation such as surfactants and solvents.)

It was also found that when the two are used in combination, a synergistic effect can be achieved. Whether you want anti-aging or whitening, you can get a 1+1>2 effect. Moreover, the stable pH values ​​of the two ingredients are around 6. Combined use will not weaken or inactivate the effect of either party.

To sum up in one sentence, the advantage of the combination of niacinamide + retinol is that the two work synergistically to amplify the effects of anti-aging, whitening, etc., while reducing the adverse reactions caused by "strong drugs", exchanging less sacrifice for greater gains!

Retinol is actually vitamin A, also known as A alcohol. In addition to its medicinal effects of treating night blindness, inhibiting tumor growth, and enhancing immunity, it also has beauty and skin care effects, such as preventing hair loss, anti-aging, removing wrinkles, fading spots, and removing acne.

1. When applied topically, retinol has many impressive anti-aging benefits.

2. If used early, it helps increase the elasticity of the skin and promotes collagen production. This can promote a soft foundation for the skin, so as we age, efforts have been made to develop ways to prevent fine lines and wrinkles, making them more difficult to form.

3. For mature skin, retinol can help increase collagen and stimulate cell renewal, thereby shedding the dead skin layer that causes fine lines and dry skin. With repeated use, retinol can also reduce dark spots and improve skin texture.

Retinol cannot be used during the day because retinol is a fat-soluble vitamin that is stable to heat, acid, and alkali, but ultraviolet rays during the day can promote its oxidative destruction, which can then cause people to tan.
