In the 1960s, researchers at the University of Pennsylvania developed a new form of vitamin A known as Retin-A, which is also known as Tretinoin. It was among the most successful patents ever made available, and it completely changed how topical skin care was applied. It is still very useful today.
It is beneficial to have knowledge of the effects that ageing has on the skin in order to fully understand how Retin-A works. The keratinocytes of the epidermis, which are the most superficial cells, have a tendency to become more absorbent and remain in place for a longer period of time. This results in the appearance of skin that is drier and rougher. Because the epidermal cells closer to the base of the epidermis do not replicate as quickly, the average life span of these cells in the outer layer is way longer, and this is reflected in their appearance. As a result of this, the pigmentation might become blotchy and rough.
Retin-A Use To Treat Acne
Retin-A is a topical medication that is only available with a doctor’s prescription. It is applied to the surface of the face in very small amounts, avoiding the eyelids, the corners of the nose, and the lips. Because it works at the cellular level, it may take several months before the full effect can be seen. The visible signs of the ageing process that appear on the skin can be considered as being reversed by using Retin-A in many different ways.
The first thing that happens when you begin using Retin-A is that the top layer of keratinocytes begins to peel off. This results in the skin becoming younger, smoother, and more evenly pigmented. The next effect that can be seen is that the epidermal cells begin to replicate at a faster rate, which ultimately results in the skin appearing and feeling softer, more robust, and healthier. The final step is that the collagen components in the dermis will eventually thicken and organise, which will result in a reduced presence of fine lines and wrinkles over time.
Acne and other precancerous conditions, such as actinic keratoses, can be treated with the help of Retin-A, which also helps improve the skin’s cosmetic appearance.
In What Ways Can Retin-A Be Applied As A Cosmetic Treatment?
A period of progressively rising dosage is typically incorporated into treatment plans. After a period of several weeks during which the topical product is applied sparingly two to three times per week, the recurrence of applications is gradually increased until a nightly routine is achieved. The concentration of the medication can be increased gradually over time. The method of delivery, either a cream or a gel, is selected according to whether the skin is naturally dry or oily.
Skin that is rough, itchy, and burning is a common adverse reaction, and it typically results from more intense application in the early phase of exposure. This issue can typically be resolved by slowing down the medication for a few days and then returning to it with a more steady rise in dosage. It is not a good idea to treat sensitive areas such as the corners of the nose, the eyelids, the lips, or the corners of the lips. After receiving Retin-A treatments, patients should stay out of the sun as much as possible. Avoiding use during pregnancy is another important safety measure to take.
In order to speed up the healing process and assist in the prevention of scarring and dyspigmentation, pre-treatment with Retin-A is immensely beneficial prior to undergoing a moderate to a deep chemical peel, laser treatments, dermabrasion, or facelift. There is no doubt that the addition of Retin-A to a beauty routine is useful.
