Things you shouldn't do after the treatment of Botulinum Toxin A (BTA)

Botulinum toxin A (BTA) has gained more recognition in the field of cosmetic, aesthetic and anti-aging medicine in recent years. The appeal of BTA is undeniable in a society that places great emphasis on personal appearance. Even so, many are hesitant to take the first step because of niggling fears and negative perceptions. I had a patient asking me this after a BTA injection, “Doctor, can I go for jogging later?” And this was my answer, “It’s not advisable to jog immediately but there is no reason why you cannot do so by tomorrow.” I notice many patients harbor various concerns regarding BTA treatment and most are curious about the dos and don’ts after the treatment. I shall try to elaborate on that as well as provide the rationale behind them.

Ladies love their facial spas and massages. And there is absolutely nothing wrong with indulging in this form of self-pampering activity. However, it is best to schedule your appointments at least 48 hours after BTA treatment. This is to prevent diffusion of the BTA into adjacent muscles, which may result in unwanted effects such as drooping of eyelids.

Strenuous exercise or activities should be avoided at least a day after the treatment.  During the procedure, as a needle is inserted into the skin, it may nick a small capillary or vein. This minor bleeding is easily arrested with gentle compression without leaving any trace of bruising. Be that as it may, if you exert yourself, your heart rate will increase and more blood will be pumped to the face. The increase in blood flow to the already injured capillary or vein may cause it to re-bleed and increase the risk of bruising.

The same theory applies to alcohol intake, which should be avoided for at least 24 hours after treatment. Alcohol causes dilatation of the capillaries and veins. As previously explained, the injured capillary or vein tends to bleed again and the risk of bruising is increased.

Patient should make a concerted effort to avoid sauna or exposure to heat immediately after BTA. After BTA injection, you may experience redness and swelling at the site of injection. Under normal circumstances, these effects will gradually fade away without any treatment. However, the redness and swelling may persist and take longer duration to subside when exposed to heat.

Swimming is also not advisable right after BTA treatment. There will be minute puncture wounds over the face where BTA was injected. The number of puncture wounds is dependent on the extent of treatment. There is an increased risk of infection when these wounds come into contact with water from the swimming pool, which most often than not, are not very hygienic.

Lastly, avoid consuming blood-thinning supplements such as ginseng, ginko bilboa, vitamin E, fish oil and etc. These supplements may increase the risk of bruising. This may not be feasible for those suffering from heart-related conditions and are on long-term aspirin or warfarin. Considering the pros and cons of withholding the medication, it is far better to continue taking your medication and endure temporary aesthetic inconvenience than risk succumbing to your disease.

Choosing the right sunscreen for your skin


How does sun’s ray actually damage our skin?

Sun produces 3 types of ultraviolet (UV) rays:

·         UVA (320 – 400nm wave length)
·         UVB (290 – 320nm wave length)
·         UVC (200 – 290nm wave length)

UVA
Penetrates deeper into the skin
Major contributor to skin damage, which leads to aging

UVB
Penetrates outer layer of the skin
Major contributor to sunburn

UVC
Almost completely absorbed by ozone layer
Does not affect the skin

What does SPF means?


SPF stands for Sun Protection Factor and refers to the theoretical amount of time you can stay in the sun without getting sunburned. For example, an SPF of 30 would allow you to stay in the sun 30 times longer than you could without sunscreen protection.

SPF
Product category
2 – 15
Minimal sun protection product
15 – 30
Moderate sun protection product
>30
High sun protection product
30 - 100
Limited gain. No extra sun protection.

What are the differences between physical sunscreen and chemical sunscreen?
Basically sunscreen that provides board spectrum UVA protection can be divided into 2 types: physical sunscreen and chemical sunscreen.

Physical sunscreen
Chemical sunscreen
Protect the skin by deflecting the sun’s rays.
Protect the skin by absorbing the sun’s rays & transform it to harmless long wave radiation.
Physical agents:
Zinc oxide paste
Micronized zinc oxide
Titanium dioxide
Absorber agents:
Avobenzone(Parsol 1789)
Amino benzoic acid
Ecamsule(Mexoryl)
Thick & opaque.
Colourless & odourless.
Should be applied 30 minutes before sun exposure.
Should be applied 30 minutes before sun exposure.
Comedogenicity: Titanium dioxide can be problematic for some people.
Comedogenicity: More irritation, some cause contact dermatitis.
Best to avoid those sunscreen that has PABA 5% as their ingredient.


A broad spectrum UVB sunscreen must have below mentioned ingredients:
-Salicylates (Octisalate, Homosalate)
-Cinnamates (Octyl methoxycinnamate)



FDA proposed a regulation on sunscreens on Dec 17, 2012, which stated that:

- Manufacturers cannot identify their products as “sunblocks”.

- Manufacturers cannot make claims that sunscreens are “waterproof” or “sweatproof”.

- Manufacturers cannot claim protection immediately on application (for example, “instant protection”) or protection for more than two hours.

- Sunscreen products that are not broad spectrum or that are broad spectrum with SPF values from 2 to 14 will be labeled with a warning that reads: “Skin Cancer/Skin Aging Alert:  Spending time in the sun increases your risk of skin cancer and early skin aging. This product has been shown only to help prevent sunburn, not skin cancer or early skin aging.” 

- Water resistance claims on the product's front label must state how much time a user can expect to get the declared SPF level of protection while swimming or sweating, based on standard testing. Only two time durations will be permitted on labels: 40 minutes or 80 minutes.
