Can Coffee and Alcohol Dehydrate Your Skin?


We all need our morning cup of joe 

Medically speaking, caffeine does not dehydrate you. However, caffeine does have effects on reducing the hydration levels of your skin. As our diet and body are deeply connected with each other, the substances we consume have the power to nourish or deprive our body of nutrients.

While coffee, alcohol and soft drinks are often not the best beverages for our skin, they may still be enjoyed once in a while. Water may not be everyone’s first choice of drink, but it is the most beneficial substance for our skin’s health and appearance. Maintaining hydration levels of the skin require a regular and consistent routine, along with healthy lifestyle changes.

Many people need a cup of coffee to jumpstart their morning. One great benefit of coffee is that it contains high amounts of caffeine increase your energy levels. However, caffeine also has diuretic effects which have a direct effect on skin hydration. [1]

Research suggests that acute ingestion of caffeine in large doses (at least 250-300 mg, equivalent to the amount found in 2-3 cups of coffee or 5-8 cups of tea) results in a short-term stimulation of urine output in people deprived of caffeine for a period of days or weeks. [2]

Excessive amounts of caffeine dehydrate the skin heavily. Dehydrated skin may result in severe dryness, excessive oiliness, inflammation and premature ageing. While many experts and skincare gurus are split on whether caffeine is the root cause of acne breakouts and dehydrated skin, It is not medically proven. 

Reddish skin due to Alcohol Dehydration

What about Alcohol?

Alcohol is more damaging to the skin. Consuming alcohol excessively may result in severe inflammatory effects in the body, especially the skin. The inflammation may cause redness, dryness, puffiness and inflammatory acne-like papules and pustules. According to medical research, alcohol has also been linked to skin diseases such as psoriasis and eczema.

Alcohol also enlarges one’s pores and may even block the natural flow of oil, which exacerbates the likelihood of acne breakouts. Elastin and collagen production is also heavily compromised, which causes the skin to lose its integrity and make it more prone to wrinkling and sagging.

Finally, alcohol dehydrates the skin [3], often resulting in the skin appearing duller and less plump. Without proper hydration or nutrients, wrinkles and fine lines will be more permanent and decrease the cell turnover of the skin. This makes it harder for the skin to regenerate and increases the chances of premature ageing.

Drinking water regularly results in deep hydration which enables the cells to function better as the skin cells are able to renew themselves at a quicker rate. Water also flushes toxins from the body, thus keeping the skin clear of acne breakouts.

That being said, this does not mean that you would have to cut off coffee and alcohol completely. Moderation is key! It is also important to keep your skin hydrated by drinking sufficient amounts of water and having a proper skincare routine. 

Another additional option would be various treatments to replenish skin hydration. At Cambridge Medical, we have a variety of treatments to serve the needs of every patient regardless of skin concern or skin types. For skin hydration purposes, one could consider PFHL Skin Hydrator, Aquashine Skinbooster and PDRN Healer treatments.

PFHL Skin Hydrator

PFHL Skin Hydrator has been coined as the “Time Reversing Injection”. PFHL Skin Hydrator has become increasingly known over the years for its effect on sagging skin. 

It is a bio-remodelling “injectable moisturiser” that results in skin laxity and targets signs of ageing. This is achieved through the bio-stimulation of collagen, elastin and fats, which are lost during the process of ageing. Other benefits of PFHL Skin Hydrator include deep skin hydration and increases volume which even outs fine lines and wrinkles which also smoothens skin texture. This boosts collagen and elastin levels.

Some benefits of PFHL Skin Hydrator include:

  • Deep hydration for skin
  • Firms, tightens and lifts the skin
  • Bio-stimulates elastin, 4 types of collagen and hydration in the 3 main skin layers
  • Smoothens out fine lines and wrinkles
  • Boosts collagen and elastin
  • Reduced risk of lumpiness due to the lack of BDDE
  • Combination of both high-molecular and low-molecular HA
  • Contains one of the highest concentrations of HA (64mg/2ml)
  • Boosts tissue repair process which is ideal for patients with severe acne scarring

The injection delivers sufficient hydration through the use of hyaluronic acid which stimulates elastin and collagen naturally without dramatically altering the facial line.

Treatment is usually administered for at least 2 sessions, 4 weeks apart. Results are usually observed after 2 sessions. 

Aquashine Skinbooster Treatment

Known as 水光针, the Aquashine Skinbooster treatment involves a series of deeply hydrating microinjections that aid in the rejuvenation of the skin. During this treatment process, hyaluronic acid is infused into the skin as it helps to retain moisture and fullness. Through the gentle smoothening out of the skin via internal means, a radiant and natural-looking complexion is achieved.

As it is a naturally occurring substance, there are hardly any major side effects to incorporating hyaluronic acid into skincare treatments.

With the use of microinjections, the skin is deeply hydrated in the treatment areas, which improve firmness, elasticity and smoothness. According to medical experts’ observations and studies, these effects have proven to be subtle and natural-looking as the stimulation process progresses regularly with consistent follow-ups of the procedure.

Aquashine skin booster treatment

Some benefits of the Aquashine Skinbooster treatment include:

  • Subtle and gradual skin plumping
  • Smoothening and softening of neck lines
  • Improved skin texture and radiance Individual results may vary according to existing conditions)
  • Minimal downtime and minimal discomfort

PDRN Skin Healer

Popularly known as 婴儿针 (baby skin injections), the PDRN Healer treatment is specially formulated to treat ageing skin better while stimulating the growth of new collagen.

PDRN Healer’s technology works by re-activating the skin’s natural healing ability. By boosting the skin’s natural healing process, its collagen structure is restored and skin elasticity is increased. PDRN Skin Healer also contains a high amount of Polynucleotides (PN), which is a more concentrated type of PDRN. PN also contains anti-inflammatory and tissue repair-stimulating agents as well as DNA Polymers.

Compared to current aesthetic or beauty treatments, which focus solely on troubled areas such as ageing skin, PDRN Skin Healer protects and repairs the skin barrier without the need for injectables or thread lifts. With this new technology, PDRN Healer is entitled to a whole new change of skin repair concept; Skin is healed and repaired while ageing problems are corrected simultaneously.

Some benefits of PDRN Healer include:

  • Anti-ageing benefits
  • Excellent skin regeneration effects
  • Improved skin texture
  • Regulates sebum secretion and improves skin hydration levels
  • Proven for safety with no adverse reactions
  • Quick visible results

PDRN Healer is very safe as its components are biocompatible with our body. After just a month of regular and consistent treatment, about 15% of patients reported a huge improvement in skin hydration and about 22% of patients recognised improvements in terms of skin elasticity.

Post-treatment, regular patients may expect to observe progressive improvements with the final results showing up between 4 to 6 weeks.
