In an interview with HT lifestyle, Dr. at Elementis Healthcare in New Delhi. Chandni Jain Gupta, MBBS, MD, Dermatologist and Beauty Physician shared a detailed guide with us, including all the necessary things from skin type match to skincare routine.
He explained, “Aha, BHA, and PHA are chemical exfolnts. They are types of acid used in skincare to remove dead skin cells, improve skin texture and promote a bright color.”
In addition, he shared a comprehensive guide on each chemical exfoliate and who is best suited for:
Various chemical exfolnts
1. Aha (alpha hydroxy acid)
- Source: Derved with fruits, milk and sugar.
- Solubility: Water soluble, so they work on the surface of the skin.
- best for: Dry, dull, or sun-stricken skin.
common types:
- Glycolic acid (from sugarcane): The most powerful, depth enters.
- Lactic acid (from milk): Gentler, hydrating as well.
- Mandelic acid (from almonds): It is good for light, sensitive skin.
benefits:
- Smooth the rough texture.
- Reduces pigmentation.
- Improves hydration by increasing natural moisturizing factors.
Precautions: Increases the sun’s sensitivity, so always use sunscreen.
2. BHA (beta hydroxy acid)
- Solubility: Soluble in oil, so they enter the pores.
- best for: Oily, acne-prone, or filled skin.
- The most common type: salicylic acid.
benefits:
- Unlogue reduces pores and blackheads and whiteheads.
- Anti -inflammatory and antibacterial properties.
- Helps control additional sebum (oil).
- Precautions: Can dry, slowly start and moisturize.
3. PHA (Polyhydroxy Acid)
- Ahas of the next generation with a large molecular structure.
- Solubility: Water soluble, but gentle and slow penetration.
- best for: For sensitive skin, rosacea, or those new exfolnts.
common types:
- Gluconolactone
- Lactobionic acid
benefits:
- Exfoliate gently without irritation.
- Provides hydration and antioxidant protection.
- Strengthens skin barrier.
Precautions: At least there is a possibility of irritation, but still starts slowly.
How to know that you need chemical or physical exfolient?
Dr. Chandni Jain clarified and said, “Instead of physical exfolnts (scrub with beads or granules), it is often recommended to use chemical exfolients (AHA, BHA, PHA) as they are more effective, safe and gentlers in a long time.”
Therefore, in other words, physical exfoliates contain textures and gritty particles that remove physically dead skin cells, while chemical exfolnts use acids such as AHA, BHA, and PHA to slowly dissolve dead skin cells.
Here are the reasons that he shared to use chemical exfolnts rather than physical people:
1. Gentler on skin obstruction
- Physical exfoliants can make micro-tier in the skin, especially if they use rough particles such as walnut shells or apricot pits.
- Chemical exfoliants work without manual friction by dissolving the bond between dead skin cells.
2. More controlled exfoliation
- Chemical exfoliants exfoliate equally.
- Physical discoloration depending on pressure and technology can be uneven.
3. Better for sensitive skin
- PHA or low concentrations of AHA/BHA such as chemical options are safe for rosacea, acne or hyperpigmentation.
- Physical scrubs can provoke or spoil these conditions.
4. Tarks specific concerns
- Bhaa enters the pores to treat acne and blackheads, while Aha fade the dark spots and smooth the fine lines.
- Physical exfoliants cannot reach the pores or effectively stimulate cellular turnover.
5. Skin supports eneval
- Chemical exfoliants can stimulate collagen production and help with long -term skin texture and tone.
When to use chemical exfoliants?
If you are confused on whether you should use scrub or chemical exfolnts such as AHA, BHA as physical exfolients; Skin condition here Dr. There are moonlight shares that can help you identify when you should use chemical exfoliates:
- Acne, uneven texture, dull, or pigmentation.
- Sensitive skin or conditions like rosacea or eczema.
- You are on retinoids or other activities that already dilute the skin slightly.
- You want frequent, long -term results with low probability of irritation.
When should you use physical exfoliants?
Skin condition here Dr. Moonlight has been shared, which makes you safe to use physical exfoliates for you:
- You have non-sensitive, flexible skin.
- You are using a very soft scrub (for example, with soft jojoba beads.)
- You want to exfoliate your body skin (for example, elbow, knee, or heels).
Matching chemical exfolient for your skin type
Dr. Chandy shared this guide to use chemical exfoliates, which is for best results based on your skin type:
1. Dry skin
- Best: AHA (especially lactic acid or mandelic acid.) Ahas exfoliate the surface of dead cells and promote hydration.
- Lactic acid is moisturizing and gentle.
- Mandelic acid is even more unhappy and good for sensitive, dry skin.
benefits: Smooth texture, increased moisture, bright tone.
2. Acne
Best: Bha (salicylic acid)
Oil soluble: Enter the pores, dissolve the sebum and dead skin. It is anti -inflammatory and antibacterial.
benefits: Cleans blackheads, reduces brakeouts, and controls oil.
3. combination skin
Best: Aha + bha combo
- Ahas exfoliates dry, flaky areas.
- Bhaa works in Oily Zone (T-Zone).
Many products now add both (eg, glycolic + salicylic acid).
benefits: Balanced exfoliation for mixed skin types.
4. Sensitive skin
Best: PHA (eg, gluconolactone or lactobionic acid)
- Large molecules mean slow, gentler penetration.
- Hydrating and antioxidant-rich.
- Suitable for skin with rosacea or eczema.
benefits: Smooth, without irritation, supports repair of obstruction.
5. Mature
Best: Glycolic acid (AHA)
- It has the smallest molecule and deep penetration.
- Collagen stimulates production.
- Shines and smooth the fine lines.
benefits: Radiation boost over time, even tone, strong skin.
