Retinols come in various forms, with some being synthetic and others non-chemical. Synthetic versions are usually derived from animals, while natural ones are plant-based. If you are a vegan, look for natural versions. Natural retinols do not contain animal components, and are therefore more environmentally friendly.
Tretinoin is stronger-harder-faster than retinol
Retinol is an important nutrient, but tretinoin is much more potent and can produce visible changes on the skin much faster. It can be used to treat acne, lighten hyperpigmentation, and reduce wrinkles and fine lines. However, it is far harsher on the skin than retinol, so people with sensitive skin should avoid it. It is also twenty times stronger than retinol.
The difference in the effectiveness of retinol and tretinoin depends on the formulation used. Some formulations use less potent retinoids, such as retinyl palmitate, which requires many more conversions before becoming active retinoic acid. Also, some of these OTC retinol products are not FDA-regulated, so it's not easy to know the strength of tretinoin.
The only difference between Tretinoin vs retinol lies in the formulation. While retinol is available over-the-counter, tretinoin can only be purchased through a dermatologist's prescription.
It stimulates “turnover” in the skin
Retinoids are substances that increase cell turnover in the skin. This is important because it helps the skin shed dead cells more quickly, which opens up pores and releases trapped bacteria and irritants. It also helps regulate the skin's natural oil production, which can prevent breakouts. It's also been studied for its effects on visible aging.
If you want to use tretinoin to treat acne, it's best to start with a lower concentration (0.01% or less) and increase the concentration gradually as your skin adapts to the treatment. Typically, tretinoin is applied as a thin layer on the face at night. A pea-sized amount is adequate for an entire face; don't use too much or you'll end up with a greasy face. Applying a water-based moisturizer afterward can reduce the drying effect of the medicine.
It increases skin's sensitivity to the sun
Tretinoin can make your skin more sensitive to ultraviolet light and sunlight. As a result, you should limit your exposure to the sun while using tretinoin. It's also a good idea to wear protective clothing and use sunscreen whenever you're outside.
Tretinoin works by speeding up the skin cell turnover cycle. New skin cells form in the deeper layers of the epidermis and migrate to the surface, while old skin cells harden and die. This process replaces the old cells with new ones. As we age, this process slows down.
Tretinoin creams and lotions are available in a variety of strengths, but you should consult your healthcare provider before beginning a new dosage. A doctor will recommend starting with a low concentration and increasing the dose over time. Generally, tretinoin lotion is applied to the skin in the morning or evening and should be applied in thin, even layers.
It stimulates collagen
Research has suggested that topical tretinoin may improve the appearance of fine lines and wrinkles that are associated with sun damage. It works by increasing collagen synthesis, and decreasing the activity of collagenase, the enzyme responsible for the breakdown of mature collagen. The research team hypothesizes that this process is the cause of clinical improvement in photodamaged skin.
Photodamaged skin often has deep wrinkles and a rough texture. Around 90 percent of skin aging is caused by UV exposure. Smoking also accelerates the process. However, tretinoin can help your skin produce new cells faster, allowing them to replace the old ones in less time.
The molecule has long been used as an anti-aging topical cream. It has been effective in treating photodamaged skin and is one of the most researched topical products in the market. There are many benefits of using tretinoin, including the fact that it is safe to use at high concentrations.
